Upload a PDF file and split it into multiple documents
PDF splitting is the process of dividing a single PDF (Portable Document Format) file into multiple, smaller PDF documents. This process extracts specific pages or page ranges from the original PDF and creates new PDF files containing only the selected pages. According to MDN Web Docs, PDFs are complex document formats that can contain text, images, vector graphics, fonts, and interactive elements, all of which are preserved during splitting.
Splitting PDF files is essential for several reasons: extracting specific pages or sections from large documents, dividing large files into smaller, more manageable documents, organizing content by topic or chapter, creating separate documents for different purposes, simplifying document sharing and distribution, and reducing file sizes for easier handling. PDF splitting is particularly valuable for extracting pages from reports, separating chapters from books, dividing presentations into sections, and organizing large document collections.
Our PDF splitter uses pdf-lib, a powerful JavaScript library, to split your PDF files entirely in your browser. This client-side processing ensures your PDF files remain completely private and secure. All splitting happens locally, so your documents never leave your device or get uploaded to any server.
A single large PDF file can be difficult to manage, share, and navigate. All content is in one file, making it hard to extract specific sections or share individual parts.

Extract only the pages you need from large PDF documents. Perfect for creating focused documents, extracting specific sections, or removing unnecessary pages. Enter page ranges or individual page numbers to get exactly what you need.
Split large PDF files into smaller, more manageable documents. This makes it easier to share, organize, and work with specific sections. Perfect for dividing reports, books, presentations, or any large document into logical parts.
Choose from three split modes: extract specific pages by range, split every N pages, or split into individual pages. This flexibility allows you to split PDFs exactly how you need them for your specific use case.
All PDF splitting happens entirely in your browser using client-side JavaScript. Your PDF files never leave your device, aren't uploaded to any server, and aren't stored anywhere. This ensures complete privacy and security for sensitive documents.
Client-side processing means instant splitting without waiting for file uploads or server processing. Split PDF files in seconds, even for large documents. No internet connection required after the initial page load.
Split PDFs maintain the original quality of the source file. No compression or quality loss occurs during splitting. All text, images, graphics, and formatting from the original PDF are preserved in the split documents.
Companies like Adobe and iLovePDF offer PDF splitting services, but they require file uploads to their servers. Our client-side approach ensures your documents remain completely private, making it ideal for sensitive business documents, legal files, medical records, and confidential materials.
Our PDF splitter uses pdf-lib, a powerful JavaScript library, to split your PDF files directly in your browser. Here's how the splitting process works:
Upload your PDF file. The tool loads the PDF and displays the total number of pages. You can then choose your split mode.
Select your split mode: extract specific pages by range, split every N pages, or split into individual pages. Enter the required parameters for your chosen mode.
Click Split PDF to process your file. The tool creates the split PDF files based on your selected mode. Once complete, download individual files or all files at once.
To get the best results when splitting PDF files, follow these best practices:
PDF splitting serves a wide variety of professional and personal needs. Understanding these use cases can help you determine when splitting is the right solution:
Extract individual chapters or sections from large PDF books, reports, or documents. This is essential for creating focused reading materials, sharing specific sections, or organizing content by topic.
Split PDFs allow you to work with specific chapters without loading the entire document, making it easier to study, share, or reference particular sections.
Extract and share only the relevant pages from a large PDF document. Instead of sending the entire file, extract the specific pages that recipients need, reducing file size and improving communication efficiency.
This is particularly useful for sharing specific sections of reports, proposals, or documents where only certain pages are relevant to the recipient.
Divide large PDF documents into smaller, more manageable files. This makes it easier to organize, navigate, and work with specific sections. Perfect for breaking down comprehensive reports, manuals, or documentation.
Split documents are easier to manage in file systems, faster to open and process, and more convenient for collaborative work where different team members need different sections.
Extract pages from multiple PDFs to create custom collections. Combine specific pages from different documents to create focused reference materials, study guides, or custom documentation.
This use case is valuable for students creating study materials, researchers compiling references, or professionals building custom documentation from multiple sources.
Extract only the pages you need, effectively removing unnecessary pages from a document. This is valuable for cleaning up documents, removing blank pages, or creating streamlined versions of large files.
Split PDFs allow you to create cleaner, more focused documents by excluding pages that aren't needed for your specific purpose.
Extract specific pages from research papers, textbooks, or academic documents for citations, references, or study materials. This is essential for academic research, note-taking, and creating focused study resources.
Split PDFs enable students and researchers to work with specific sections of academic materials without managing entire large documents.
Upload your PDF file using the upload button or drag and drop it into the designated area. Choose your split mode: extract specific pages by range (e.g., '1-3,5,7-9'), split every N pages, or split into individual pages. Click Split PDF to process your file. Once splitting is complete, download your split PDF files.
Yes, our PDF splitter is 100% free to use. There's no registration required, no account needed, and no hidden fees. All PDF splitting happens in your browser, so your files never leave your device and remain completely private.
Our PDF splitter offers three split modes: Range mode allows you to extract specific pages or page ranges (e.g., '1-3,5,7-9'). Every N pages mode splits the PDF into multiple files, each containing N pages. Single page mode splits the PDF into individual pages, creating one file per page.
Yes! Use the Range mode to extract specific pages. Enter page numbers or ranges separated by commas (e.g., '1-3,5,7-9' to extract pages 1, 2, 3, 5, 7, 8, and 9). The tool will create a new PDF containing only the selected pages.
Absolutely. All PDF splitting happens entirely in your browser using client-side JavaScript. Your PDF files never leave your device, aren't sent to any server, and aren't stored anywhere. This ensures complete privacy and security for sensitive documents, business files, and personal information.

The built-in iOS Files app can preview, move, rename, and share PDF documents, but it has no built-in page splitting capability of any kind. Apple's Shortcuts app can perform some basic PDF operations programmatically, but building a split workflow in Shortcuts requires assembling multiple actions by hand and does not provide a visual page selector or thumbnail preview, which makes it impractical for anyone other than a dedicated automation hobbyist. Third-party PDF apps on the App Store, including PDF Expert, Adobe Acrobat Mobile, and PDF Viewer Pro, all offer page splitting features, but every one of those options requires either a paid subscription or a one-time in-app purchase to unlock the splitting functionality. PDF Expert charges 79.99 US dollars per year, Adobe Acrobat Mobile charges 9.99 US dollars per month for full editing access, and the others fall into a similar pricing band. For a user who needs to split a PDF once a month or even once a week, none of those subscriptions are remotely justified by the actual usage volume.
FixTools running inside Safari or Chrome on iPhone provides the same splitting functionality as the desktop version of the tool with absolutely no installation, no in-app purchase, and no account required. The iOS browser file picker integrates cleanly with the Files app, with iCloud Drive, with Dropbox, with Google Drive, and with any other storage provider that has been registered on the device through the standard iOS provider extension system. When you tap the upload area in FixTools, iOS presents the standard document picker view, giving you direct access to PDFs from any of those locations without having to copy the file into a working folder first. After the split finishes, each output file downloads via the browser and iOS offers to save it directly to Files in any folder you choose, or to open it in another app such as Mail, Slack, or Dropbox for immediate onward sharing.
Performance on iPhone depends meaningfully on the A-series chip generation and the amount of RAM available in your specific device model. An iPhone 14 or 15 with the A15 or A16 chip and 6 gigabytes of RAM handles PDFs up to about 80 megabytes without any noticeable processing delay. An iPhone 12 with the A14 chip and 4 gigabytes of RAM can manage files up to 50 megabytes comfortably in either Safari or Chrome. Older models such as iPhone X and iPhone 11 with 3 to 4 gigabytes of RAM may run slowly on files larger than 30 megabytes, particularly when those files contain many high-resolution scanned images. For anything over 60 megabytes on any iPhone, the fastest workflow is usually to split on a Mac or PC and then AirDrop or email the resulting parts back to the phone for distribution. Safari on iOS 16 and later generally outperforms Chrome on the same iPhone for memory-intensive browser tasks because of Safari's tighter integration with the WebKit memory allocator.
A specific iOS quirk worth knowing is how Safari handles the download itself. When the split completes, Safari triggers a download and presents an options sheet asking you what to do with the file. The default choice is often "View" which opens the file in Safari's built-in preview, but the choice you usually want is "Save to Files" so that the output PDF persists in a known location rather than only existing in Safari's ephemeral download cache. Tap the share icon at the bottom of the preview if you opened it accidentally, then choose "Save to Files" from the share sheet to recover the file properly. Once it is in Files, you can move it to iCloud Drive for sync with your other devices, attach it to a Mail message, or open it directly in any other PDF-aware app installed on your phone.
Open FixTools in your iPhone browser. Tap the upload button and select your PDF from the Files app or iCloud Drive. Choose your split options and download the result directly to your iPhone.
Step-by-step guide to split a pdf on iphone:
Open Safari or Chrome on your iPhone
Launch your preferred browser on iOS, either Safari or Chrome, and navigate to fixtools.io by typing the address into the URL bar at the top of the screen. The site loads quickly even on cellular connections because the splitter's JavaScript bundle is optimized for mobile delivery and cached aggressively by the iOS browser engine for repeat visits.
Open the PDF Splitter
Tap the PDF Splitter card from the tools menu on the FixTools homepage. The splitter loads in your mobile browser instantly with no app download required at any step. The interface is responsive and adapts to the narrower screen width of an iPhone, presenting larger touch targets for the upload button and the split options compared to the desktop layout.
Upload your PDF from Files or iCloud
Tap the upload area at the centre of the splitter page to open the iOS standard document picker. From there select your PDF from the Files app local storage, from iCloud Drive, from Dropbox, Google Drive, or any other cloud provider registered on the device. iOS handles the file handoff transparently and the splitter receives the file in browser memory ready for processing.
Choose split options
Select how to split your PDF using the on-screen mode selector: by a custom page range with specific start and end pages, by every page becoming an individual file, or into equal-size parts at a fixed page interval. For most iPhone use cases, page range mode is the most common choice because the goal is usually to extract one specific section rather than burst the document into single pages.
Split and save
Tap Split PDF and the tool processes your document locally on the phone. When the operation finishes, tap the download link and choose Save to Files when iOS presents the share sheet. Place the output PDF in your preferred iCloud Drive folder or in On My iPhone storage so you can find it again, then share it via Mail, Messages, or any other app installed on the phone.
Common situations where this approach makes a real difference:
Remote worker on the go
A sales representative receives a 45-page commercial contract PDF via email on her iPhone while travelling between client meetings on the same day. She needs to forward only the pricing section on pages 18 through 22 to a colleague back at the office for a quick sanity check before her afternoon call. She opens FixTools in Safari, taps the email attachment to save it to Files first, selects the file from the splitter's file picker, enters the range 18-22 in the input field, and downloads the 5-page pricing PDF in under a minute. She attaches it to a new email and sends it without ever touching a computer or laptop during the trip.
Student
A graduate student has a 200-page textbook PDF saved in iCloud Drive and needs only Chapter 3, which runs from page 67 to page 94, for a seminar discussion happening that afternoon. He opens FixTools in Safari on his iPhone 15 Pro during the bus ride to campus, selects the file directly from iCloud through the document picker, enters the range, and saves the resulting 28-page chapter PDF back into the same iCloud Drive folder. The split takes about twelve seconds on the A17 chip, and by the time he arrives at the building he has the chapter file ready to read in Books or Preview.
Property manager
A property manager receives a 30-page residential lease agreement on her iPhone from the legal team and needs to send the tenant only the rules and regulations section on pages 14 through 22 ahead of the move-in inspection scheduled for the following morning. She uses FixTools in Safari on her iPhone 13 to extract those 9 specific pages into a focused PDF and then sends the extracted file to the tenant directly through Messages as an attachment. The whole operation, from opening the email to sending the trimmed file, takes less than two minutes from start to finish.
Healthcare professional
A nurse practitioner has a 60-page patient intake PDF bundle stored in her Files app folder for active patients and needs to extract a single patient's intake form on pages 41 through 44 to attach it to the corresponding electronic health record. Because she cannot upload patient data to external cloud services under HIPAA, FixTools' browser-based local processing is the right tool. The extraction in Safari takes about five seconds, and she saves the resulting 4-page PDF to Files for immediate upload to the EHR system through its own mobile interface.
Get better results with these expert suggestions:
Use Safari over Chrome on iPhone for large PDF files
Safari on iOS has tighter integration with the WebKit memory allocator and access to the full device RAM allocation for browser processes, while Chrome on iOS actually runs as a WebKit wrapper with slightly tighter memory limits imposed by App Store rules. For PDFs over 30 megabytes on any iPhone, Safari will typically process the file faster and is noticeably less likely to reload the page mid-operation due to memory pressure. Use Safari as the default for any non-trivial PDF splitting task on iPhone.
Save output to Files app, not just download
When the split completes and the download prompt appears in Safari, choose Save to Files from the share sheet rather than just opening the file directly in a viewer. Saving places the output PDF in your iCloud Drive or On My iPhone storage at a path you choose, where you can find it later. Files that are only opened from the browser download link without an explicit save action may not persist to a findable location and can be cleared by Safari when it manages cache storage automatically.
Access PDFs from email attachments directly
If the PDF you need to split arrived as an email attachment in Mail, tap and hold the attachment, then choose Save to Files from the menu that appears. Once it is in the Files app at a known path, open FixTools in Safari and access the file via the standard document picker. Trying to open the attachment directly in a browser sometimes creates a temporary copy at a path the browser cannot read back, leading to confusing upload failures that are hard to debug on a phone.
Close background apps before splitting files over 40MB on older iPhones
On iPhone 11 or earlier models with 3 to 4 gigabytes of RAM, background apps compete with Safari for the limited memory pool available to applications. Before uploading a PDF larger than 40 megabytes, double-press the Home button on Touch ID models or swipe up and pause on Face ID models to open the app switcher, then dismiss apps you do not currently need. This frees RAM for the browser processing and reduces the chance of Safari reloading the splitter page during the operation, which would force you to start over.
