About the Merge PDF tool

100% private: This tool runs entirely inside your web browser. Your files are never uploaded to a server — they never leave your device. That makes it faster, and it means your documents stay completely confidential.

How to merge PDF files

Select two or more PDF files, drag them into the order you want, and click Merge. Tallywise stitches every page together into one clean PDF that you can download immediately.

Why merge PDFs?

Combining files is handy for assembling reports from multiple sources, joining scanned pages, or bundling invoices and receipts into a single document for sharing or archiving.

Frequently Asked Questions

Is there a limit on how many PDFs I can merge?

There is no fixed limit. Because the merge happens on your own device, the practical limit is your device's available memory. Dozens of typical documents merge without issue.

Are my files uploaded to a server?

No. The entire merge runs in your browser using JavaScript. Your files never leave your computer, which keeps them private and makes the tool fast.

Can I change the order of the files?

Yes. After adding your files you can drag them up or down to set the exact order the pages should appear in the merged document.
