How to Combine Receipts Into One PDF | Expense Reports

When expense-report or tax-filing season comes around, sorting through the receipts piled up in your wallet and bag is a chore. If you photograph them with your phone and combine them into a PDF instead of keeping a stack of paper, finding, sending and storing them gets much easier. This article covers how to combine receipts into a PDF and how to organize them so you are not stuck later.

In short, scan the paper you have on hand one receipt at a time with “Scan” to make one PDF, and convert photos you have already taken in one go with “Create PDF from images.” Keeping separate files by month or purpose makes them easier to find later.

What Gets Easier When Receipts Are PDFs?

  • Submitting is easier: whether you attach a file to an expense report or email it to accounting, one PDF means doing it once
  • They are easier to find later: group them by month and you can quickly find “that business trip's receipts.” Run OCR and you can even search by store name or amount
  • You avoid loss and fading: the print on thermal-paper receipts tends to fade over time. Photograph them early and you keep a record while it is still legible
Whether a PDF of a receipt meets tax record-keeping requirements (such as Japan's Electronic Books Preservation Act) depends on the transaction and how it is stored. This article covers how to use the app and does not judge those requirements. If you need to be sure, check the National Tax Agency's guidance or ask a tax accountant or your company's accounting staff.

How Do I Combine the Receipts I Have Into One PDF?

  1. Open PDF Toolkit and tap “Scan” at the bottom right of the Library screen
  2. Lay each receipt flat on a table and photograph it with all four corners in view. You can keep adding pages after each shot
  3. Check the frame that was detected automatically, and drag the corners if it is off
  4. When you save, all the pages you shot are added to your library as one PDF
  5. Use “Rename” (the pencil icon) on the document screen to give it a name that shows the month or purpose

One scan can hold up to 30 pages. In a month with lots of receipts, scan them in several PDFs, such as first half and second half, then combine them with “Merge PDFs” under Tools (choose two or more PDFs to merge).

How Do I Make a PDF From Photos I Already Took?

If the receipts are already in your camera roll, “Create PDF from images” under Tools turns the photos you pick into one PDF. In this method, though, each photo becomes a page as it is, with no straightening or cropping. If many photos are shot at an angle, re-shooting with “Scan” gives a cleaner result.

How Can I Organize Them So They Are Easy to Find?

  • Split by month or purpose: give each file a name you will understand later, such as “2026-10_transport”
  • Make the text searchable: running “Make text searchable” (OCR) under Tools lets you search by store name or amount. Faded print and handwriting can be harder to recognize, though. See How to Search Words in a PDF on Android too
  • If the rule is one PDF per receipt: set “Pages per file” to 1 in “Split PDF” under Tools, and you get one PDF per page (“Split PDF 1,” “Split PDF 2,” and so on)
  • If the orientations are mixed up: fix one page at a time with “Rotate” in the page's ︙ menu

What Should I Check When I Submit or Share?

  • Check the recipient's rules first: match them on whether it should be one PDF or one per receipt, and on the file size limit
  • The free version adds a watermark when you share: PDFs you share or send carry a small “Created with PDF Toolkit” at the bottom of each page. If that matters for a document going outside your company, use “Export without watermark” (watching one video ad covers that PDF once) or the PRO version (one-time purchase)
  • When the file is large: “Compress PDF” under Tools can shrink it, but since it rebuilds pages as images, text can no longer be searched or copied and image quality drops. Check that the amounts are still readable afterward. See PDF Too Big to Send? Compress, Split or Extract Pages for details
  • Watch what is visible: a receipt can show a personal name or part of a card number. Check that nothing the recipient does not need is included before you send

Summary

Receipts can be combined into one PDF with just your phone: “Scan” for paper you have on hand, “Create PDF from images” for photos you already took. Name the files by month or purpose, and make them searchable with OCR when you need to, and expense reports and tax filing get easier to prepare for.

Frequently Asked Questions

Q. Should I make a separate PDF for each receipt?

A. It depends on the recipient's rules. To combine them, shoot them one after another with “Scan.” To separate them, run “Split PDF” under Tools on the combined PDF with “Pages per file” set to 1.

Q. What if my receipts end up in different orientations?

A. Open the document in the Library and choose “Rotate” from the ︙ menu of the page you want to fix. Each tap turns it 90 degrees clockwise and saves immediately.

Q. Can I search the text or amounts in a receipt PDF?

A. Run “Make text searchable” (OCR) under Tools and you can search by store name or amount. Faded print and handwriting can be harder to recognize.

Q. Can I photograph thermal-paper receipts clearly?

A. Shoot in a bright place at an angle that avoids glare, and they are easier to read. If the print has faded a lot, even a photo may not be legible, so it is best to photograph them early.

Q. Does keeping a PDF satisfy tax record-keeping requirements?

A. This article cannot judge that. The requirements depend on the transaction and how the record is stored, so check the National Tax Agency guidance or ask a tax accountant or your company accounting staff.
