Splitting a PDF into two is the simplest variant of a page range operation, but choosing the right split point still requires a moment of thought before you start. The most straightforward case is a midpoint split where a 40-page document becomes two equal 20-page files. This works well for annual reports where the first half covers the business narrative and the second half contains financial statements, or for training manuals where Part 1 covers theory and Part 2 covers practical exercises. To find the midpoint of any document, divide the total page count by 2 and use that as the split point. A 56-page document splits at page 28, producing a 28-page first file covering pages 1-28 and a 28-page second file covering pages 29-56. For odd totals, round down for Part 1 so that Part 2 carries the extra page rather than the other way around.
Not every two-part split falls neatly at the midpoint. A 120-page legal brief may need to split at page 85 to separate the argument section running across pages 1-85 from the exhibits packed into pages 86 through 120. A book PDF may split at the exact chapter boundary, which you find by checking the table of contents page numbers, rather than at the 50 percent mark of the file. For asymmetric splits, the key step is identifying the boundary page before uploading. Open the PDF in any viewer, scroll to the last page of the first section, note the page number shown in the viewer bar at the bottom or top of the window, and use that number as your split point in FixTools. Skipping this preview step is the single most common cause of having to re-run the split because the boundary landed one page off from where you intended.
A common confusion with two-part splits is whether the split page itself goes into the first file or the second file. FixTools includes the split page in the first file. If you split at page 20, the first output contains pages 1-20 and the second contains pages 21 to the end of the document. This is the standard behavior for page-range splitting across every major PDF tool, and it matches the mental model most users have when they say "split at page 20." If you want page 20 in the second file instead because it carries the heading or cover for the section you want to lead Part 2, set your split point to page 19. The first file becomes pages 1-19 and the second file becomes pages 20 to the end, which places the heading at the top of Part 2 where it reads naturally.
Two-part splitting also shines for collaborative review workflows where one person is responsible for the first half of a document and another for the second. By producing two physically distinct files, each reviewer can mark up their section in their preferred PDF tool without worrying about overwriting the other reviewer's annotations. When the review is complete, the two annotated halves can be merged back together using FixTools PDF Merger, which preserves all the annotations and form fields from both files in their original positions. This split-review-merge cycle is faster than serial review on a single shared file, and it scales naturally to any document where the natural division of labor falls along a single page boundary.
Upload your PDF and enter the page number where you want to split it. FixTools creates two files: pages 1 to N and pages N+1 to the end.
Step-by-step guide to split a pdf into two parts:
Upload your PDF
Open the PDF Splitter in your browser and upload the PDF you want to divide into two parts by either dragging it onto the upload area from your file manager or clicking the area to open the standard file picker. The file is parsed locally in your browser and the total page count appears once parsing completes, giving you the upper bound for your split point.
Set the split page
Enter the page number where the split should occur in the labelled input field. Pages 1 through that number become Part 1, and the remaining pages from the next page through the end of the document become Part 2. Pages are counted from 1 based on physical position in the file, not on printed page numbers visible in the document footer.
Split
Click the Split PDF button and FixTools generates both output files in a single pass through the source document. Processing typically completes in a few seconds for normal office documents and within twenty seconds for documents over one hundred pages. A progress indicator confirms the operation is running so you know the tool has accepted your input correctly.
Download both parts
Download each part separately to your device by clicking the two download links that appear after splitting finishes. The files are named with sequential suffixes so they sort correctly when placed side by side on disk. Rename them immediately to descriptive names that reflect their actual content before moving them into a project folder alongside other documents.
Common situations where this approach makes a real difference:
Annual report distributor
A chief financial officer needs to send the narrative section covering pages 1 through 32 of a 64-page annual report to the corporate communications team for proofreading, while the audited financial statements running from page 33 through page 64 go separately to the audit committee chair. He splits the 64-page PDF at page 32 in FixTools, producing two equal 32-page files in under fifteen seconds. Each team receives only the section relevant to their review, and neither output file exceeds 4 megabytes, which fits comfortably into any email attachment limit imposed by either recipient organization.
Training course administrator
A human resources administrator has a 90-page new-hire onboarding manual and needs to distribute Part 1 covering company policy on pages 1 through 45 before the first day of the new starter's employment, then Part 2 covering role-specific procedures on pages 46 through 90 after the first week of orientation. The midpoint split at page 45 takes one operation and produces two correctly bounded PDFs ready for the learning management system upload queue. Each file fits cleanly into one weekly module slot.
Legal paralegal
A litigation paralegal has a 110-page court filing where the substantive brief runs from page 1 through page 78 and the supporting appendices occupy pages 79 through 110. She needs the appendices filed separately with a different docket reference number because the local court rules require exhibits to be filed as their own document. Setting the split at page 78 in FixTools produces a 78-page brief file and a 32-page appendix file, both preserving all embedded text, stamp annotations, and electronic signatures from the original filing without any rasterization.
E-book self-publisher
A self-publisher has a 200-page PDF manuscript and wants to send the first 100 pages, which include the prologue through the end of Chapter 8, to a beta reader for early feedback before sharing the complete work. He splits the manuscript at page 100, producing a 100-page review copy in about eight seconds on his desktop. The second half of the book stays on his hard drive and out of circulation until he has incorporated the first reader's feedback, reducing the risk of an early draft of the ending leaking to the wider world.
Get better results with these expert suggestions:
Check your page viewer before choosing the split point
Open the PDF in Chrome by dragging it onto a new browser tab, or in Preview on macOS, and scroll carefully to the last page of the first section you want as Part 1. The page number shown in the viewer toolbar reflects the physical position in the file, which is exactly what FixTools uses for its range numbers. For documents containing Roman numeral front matter such as a title page and copyright page, the physical page number differs from the printed page number by the count of front matter pages, so always verify the actual position in the viewer rather than trusting the printed number in the document footer.
Splitting at page N puts page N in Part 1
FixTools includes the split page itself in the first output file rather than the second. A split entered at page 40 produces Part 1 covering pages 1 through 40 and Part 2 covering pages 41 through the end of the document. If the boundary page conceptually belongs to the second section, such as a chapter title page that opens the next major part of the document, set your split point to page 39 instead so that the chapter title opens Part 2 as its first page. This small adjustment makes the resulting files read more naturally when opened independently.
For equal halves, divide total page count by 2
To find the midpoint of any PDF for a balanced two-part split, check the total page count shown in your viewer's page counter as "X of Y", divide Y by 2, and use the result as your split page in FixTools. For odd total page counts, round down for the first half so the second half carries the spare page. A 55-page document splits at page 27, producing a 27-page Part 1 covering pages 1 through 27 and a 28-page Part 2 covering pages 28 through 55. This convention keeps the workflow predictable.
Compress each half independently if sizes differ widely
When a PDF has image-heavy pages concentrated in one section, the two output halves can differ significantly in file size even though they have similar page counts. If Part 1 ends up at 2 megabytes and Part 2 is 18 megabytes because of embedded photographs in the second half, run only Part 2 through the FixTools PDF Compressor. Compressing Part 1 would waste time for negligible savings, while Part 2 typically drops to 4 or 5 megabytes at medium compression quality with no visible loss in reading clarity at normal magnification levels.
