Turning scanner output into a usable archival PDF

Document scanners broadly produce two kinds of output: native multi-page PDF (modern office MFPs and ADF scanners) and image-per-page folders (older flatbed scanners, phone scanning apps in image mode, document camera setups). FixTools handles the second case by combining the folder of images into a single PDF. The output mirrors what the modern MFP would have produced directly, freeing you from the manual stitching step.

The conversion process is straightforward but requires attention to order and page size. Order should match the scan order, which is usually preserved by sequential filenames (scan001, scan002, ...) that sort alphabetically. Page size should match the physical paper: A4 for European, UK, Asian, and Australian standards; US Letter for North American documents. Matching the page size ensures the PDF prints at 1:1 scale, which matters for legal and archival use.

FixTools embeds each scan into the PDF using the best filter for the source format. JPG scans pass through with DCTDecode (lossless to the PDF, lossy because the JPG was lossy to start with). PNG scans use FlateDecode (fully lossless). TIFF scans, common in archival contexts, are parsed by the built-in TIFF decoder and embedded with the appropriate filter (FlateDecode for color, CCITTFaxDecode for bilevel). Multi-page TIFFs contribute their pages in order automatically.

For sensitive scans (legal, medical, financial), the in-browser conversion provides a privacy advantage over server-side scanner-to-PDF services. The scan data never leaves your device, which is verifiable in browser developer tools and important for compliance contexts that restrict third-party processing of sensitive content. Combined with full-disk encryption on the local machine, the workflow is end-to-end secure for high-sensitivity archival work.

How to use this tool

💡

Drop your scanner output images onto FixTools. The tool produces a multi-page PDF matched to standard paper sizes.

How It Works

Step-by-step guide to scan to pdf converter:

  1. 1

    Scan each page to image

    Use your scanner to save each page as an image (JPG, PNG, or TIFF). 300 DPI is the standard archival resolution. Save to a single folder for easy batching.

  2. 2

    Open FixTools

    Navigate to the FixTools Image to PDF page. The converter supports every scanner output format.

  3. 3

    Drop the scan folder

    Select all scan files and drag onto the upload zone. The tool sorts alphabetically by filename and shows per-page thumbnails.

  4. 4

    Set paper size and convert

    Choose A4 or US Letter to match the physical paper. Click Convert. The multi-page PDF downloads to your records folder.

Real-world examples

Common situations where this approach makes a real difference:

Office consolidating scan folder backlog

An admin assistant inherits a backlog of scan folders from a flatbed-only era of the practice. FixTools batches each folder into one PDF over a single afternoon, replacing 200 scan folders with 200 tidy PDFs in the document management system.

Lawyer combining client-supplied scan pages

A client sends a solicitor 30 page images of a contract they scanned on their home printer. FixTools combines them into one PDF on the solicitor's machine in under a minute, with no client data passing through a third-party server.

Accountant assembling receipt scans for tax

An accountant scans paper receipts from a client at year-end, producing 80 JPG files. FixTools combines them into one categorised PDF per expense type, the PDFs go into the client's tax file, and the originals are archived.

Researcher archiving printed records from a library

A researcher prints and scans archival library material into JPG pages. FixTools combines the page images into research-PDF artefacts per record, archived to the researcher's reference manager.

Pro tips

Get better results with these expert suggestions:

1

Use ADF scanners for automatic page ordering

An ADF (automatic document feeder) names pages in scan order, eliminating manual reordering. If your scanner has one, prefer it over flatbed for multi-page documents.

2

Scan at 300 DPI for archival quality

300 DPI matches the typical print resolution and provides enough detail for OCR. 150 DPI is too low for printing; 600 DPI is overkill except for fine-print documents.

3

Bilevel scan for text documents to save space

For text-only documents, set the scanner to bilevel (1-bit black and white) mode and save as TIFF with CCITT compression. FixTools preserves the CCITT compression in the PDF, producing tiny file sizes (30 KB per A4 page) appropriate for archival text.

4

OCR the PDF after conversion if you need search

FixTools does not add OCR. For searchable PDFs, run the output through an OCR tool such as Adobe Acrobat Pro recognise text, Apple Preview Live Text, or a dedicated OCR service.

FAQ

Frequently asked questions

JPG, PNG, TIFF (single and multi-page), and BMP. The tool detects each format from its magic bytes and applies the right decoder. Mixed formats in one batch are supported.
You choose the page size: A4, US Letter, Legal, or fit-to-image. Match the physical paper for accurate 1:1 reproduction when printed. Fit-to-image sizes each page to its source image individually.
No, not from raw scans. PDF contains the scan pixel data, not text. For search, run OCR after conversion. FixTools focuses on the assembly step.
No. The conversion runs in your browser locally. Scans never leave your device. Important for sensitive scans like legal or medical records.
Practical limit is browser memory. Documents up to roughly 100 pages at 300 DPI convert reliably on typical laptops. Above that, split and merge.
Yes. Each TIFF page contributes one PDF page in the original order. A 20-page TIFF becomes a 20-page PDF in one conversion step.
Yes. Bilevel TIFF with CCITT Group 4 compression produces extremely small file sizes for text documents (30 KB per A4 page). FixTools preserves the CCITT compression in the PDF.
