Combine a Stack of Scanned Tax Receipts Into One PDF for Your Accountant

Every freelancer and small-business owner hits this wall: you download receipts from office supply stores, client invoices, and bank statements as individual PDFs, and now you need to send them to your accountant as one organized file. The process is tedious because most tools either require a monthly subscription, force you to upload sensitive financial documents to a server, or make you reorder pages one at a time. You don't need another SaaS bill, you need a fast, private way to stack those files into a single PDF.

Here's the shape of the solution: you open PDF Merge & Split in your browser, drag all your receipt PDFs into the merge window, reorder them by the date in the filename, click merge, and download a single file. No uploads, no account creation, no monthly fee. The whole thing takes about 90 seconds, even with 30 to 50 files.

Step by step

1. Gather your receipt PDFs into one folder on your computer. Make sure the filenames include the date, for example 2026-01-15-office-supplies.pdf. If they don't, rename them before you start, it saves time later.
2. Open PDF Merge & Split in your browser. The extension works locally, so no files leave your device.
3. Drag all your receipt PDFs from the folder into the merge window. You can select multiple files at once by holding Ctrl (Windows) or Command (Mac) while clicking.
4. Reorder the files chronologically by dragging them up or down in the list. If your filenames have dates, you can sort them quickly by looking at the names. This step ensures your accountant sees January receipts before February ones.
5. Optional: compress images before merging. If your scanned receipts are large (like 10 MB each from a high-res scanner), toggle the compression option to downscale images. This shrinks the final file size so it fits in an email attachment.
6. Optional: add a password to protect the output. If you're emailing the PDF, a password keeps the data secure even if the email is intercepted.
7. Click the merge button. The extension processes everything locally, your files never touch a server. This usually takes a few seconds, even with 50 files.
8. Name the output file something your accountant will recognize, like Q1-2026-receipts.pdf.
9. Download the merged PDF and save it to your desktop.
10. Email it to your accountant as an attachment. If you added a password, include it in a separate message or via a secure channel.

Why this works better than Smallpdf or Adobe Acrobat

The obvious alternative is Smallpdf, which costs about $9 per month for the merge feature, or Adobe Acrobat Pro at around $20 per month. Both require you to upload your files to their servers. For tax documents, which contain your Social Security number, business revenue, and personal address, uploading to a third party introduces unnecessary risk. PDF Merge & Split processes everything in your browser, so your receipts never leave your computer. You also avoid the monthly subscription. If you only merge receipts once per quarter, paying $108 per year for Smallpdf is wasteful. With the extension, you pay once (or use the free tier for smaller merges) and you're done.

If you have receipts with bookmarks (for example, a multi-page bank statement with section markers), PDF Merge & Split can also split by bookmark before merging. But for a straightforward stack of scanned receipts, the drag-and-drop merge is all you need. No learning curve, no hidden fees, and your data stays private.
