How to Turn Receipts Into One PDF for Expense Claims

To turn receipts into a single PDF for an expense claim, photograph each receipt flat on a dark surface in good light, crop and brighten the photos if needed, then add them to an image-to-PDF tool in the order of your expense list and save one file. ToolMany's Image to PDF does this in your browser. If you also have e-receipts that are already PDFs, combine everything with Merge PDF. Name the file clearly and check it is under your expense system's upload limit.

Why one PDF helps

Expense systems and finance teams generally prefer one tidy file per claim:

• reviewers can check each line against its receipt without opening 15 attachments;
• nothing gets lost or attached to the wrong claim;
• the file can be archived with the claim for audits.

Some systems accept individual images, but even then, a single PDF is easier to email, store and resend.

Step 1: Photograph receipts the day you get them

Paper receipts, especially thermal till receipts, fade over time and with heat and light. A photo taken the same day is often the only readable copy a few months later.

For a good photo:

• Place the receipt on a dark, plain surface. White receipts on a dark table give clear edges, which makes cropping easy.
• Flatten it. Smooth out folds; weigh the corners down with coins if it curls.
• Use even light. Daylight from a window is ideal. Avoid your own shadow and the phone's flash, which can glare on glossy paper.
• Hold the phone directly above so the receipt is not trapezoid-shaped.
• Fill the frame, but leave a little margin around the edges.
• Long receipts: photograph in two overlapping halves if one shot makes the text too small, and keep both images in order.

Many phones have a document-scanning mode, in the notes, files or camera app, that crops and straightens automatically. It works well for receipts. See scanning documents with your phone for more tips.

Step 2: Make faint receipts readable

Faded thermal receipts often come out grey and low-contrast. Before building the PDF:

1. Open the photo in the Image Editor.
2. Increase contrast and slightly reduce brightness to darken the print.
3. Convert to greyscale if the colour adds nothing.
4. Crop away the table around the receipt.

Our guide to fixing dark or faded photos explains the sliders in more detail. Do not edit the content of a receipt in any way other than improving legibility; finance teams rely on receipts being genuine.

Step 3: Put them in the right order

Order the receipts the same way as the lines on your claim: usually by date, or by the order of the expense form. Renaming files with a number prefix (01_taxi.jpg, 02_hotel.jpg) keeps them in order in any file picker.

Step 4: Build the PDF

1. Open Image to PDF.
2. Add all the receipt photos. Pages follow the order in which the files are added, which is why the number prefixes from step 3 help: most file pickers sort by name.
3. If a photo is wrong or out of place, remove it from the list and add the correct one.
4. Choose a page size; A4 or Letter is usually best for printing and reviewing, while "original" keeps each photo's own shape.
5. Create and download the PDF, then open it and scroll through once to check every receipt is readable.

If you also have e-receipts or invoices already in PDF form (hotel folios, online orders, train tickets), combine them with your receipt PDF using Merge PDF. You can move files up and down to match your claim before merging.

Step 5: Check the file size

Phone photos are large. Fifteen receipts at 3–4 MB each can produce a PDF over 50 MB, too big for many systems and email.

• Compress the photos first with the Image Compressor. Receipts stay perfectly readable at a fraction of the size, because they are mostly plain text on white.
• Or resize them to about 1500 pixels on the long side before building the PDF.

Our guide to getting a PDF under an upload limit covers other options.

Step 6: Name and file it

A clear file name saves everyone time:

2026-10_Expenses_Ali-Hamza_Lahore-trip.pdf

Keep a copy until the claim is paid, and longer if your employer or tax rules require. Many organisations ask employees to keep originals for a set period; check your company policy.

A routine that works for frequent travellers

• Photograph every receipt immediately, before it goes into a wallet.
• Keep them in one phone album or folder per trip or per month.
• Write a quick note in the photo name or a notes file for anything unclear ("client dinner, 3 people").
• At the end of the trip or month, build the PDF in one sitting.

Ten minutes a month is much less painful than reconstructing a stack of crumpled receipts at the claim deadline.

When a receipt is missing

It happens. Most organisations have a process, often a signed declaration describing the expense, the date, the amount and why the receipt is missing. Some accept a bank or card statement line as supporting evidence. Ask your finance team rather than recreating a receipt yourself; a self-made receipt for your own expense claim is not acceptable proof.

Privacy

Receipts can show partial card numbers, addresses and what you bought. Send the claim only through your organisation's expense system or to the right finance contact. ToolMany's image and PDF tools work in your browser, so your receipts are not uploaded.
