Scanners that save one image per page — and phone cameras — leave a document scattered across image files. PDF Tool combines them into a single PDF in the right page order, free of charge.

Four simple steps

  1. 1

    Open Images to PDF and select all the scanned images.

  2. 2

    Check the thumbnails and arrange them in document order.

  3. 3

    Choose Fit to A4 for a uniform, submission-ready layout.

  4. 4

    Create the PDF and save it under the document's name.

Tips for the best result

  • Save scans as JPEG or PNG for reliable loading.
  • Pages with mixed orientations are auto-adjusted in A4 mode.
  • Verify the final page count if you are worried about missing pages.

Why digitize paper as PDFs

Contracts, warranties, and medical results kept on paper are slow to find and hard to share. Stored as one PDF per document, they become searchable by filename and instantly mailable.

A PDF also reads better later than a folder of images: the page order is fixed and the file behaves like a document.

Keeping pages in order

Scanning in page order saves rearranging, but mistakes are cheap to fix — drag the thumbnails into place instead of rescanning.

Some scanning apps break one document into several images automatically; selecting them in filename order keeps rearranging to a minimum.

If one batch contains several documents, create one PDF per document for easier long-term filing.

Safe for sensitive paperwork

Scanned paperwork usually carries personal or contractual details. PDF Tool builds the PDF inside your browser without uploading the images, so those details never leave your device.

Frequently asked questions

Can black-and-white and color scans be mixed?

Yes. Any loadable image joins the same PDF regardless of color.

What scan resolution should I use?

For text documents, 200-300 dpi balances readability and file size well.

Is the combined document stored anywhere?

No. Processing stays on your device and the service keeps no copy.
