How to merge PDF files
Step 1
Drop two or more PDF files into the box above — order them with the arrows.
Step 2
Click Merge PDFs. The files are combined by code running in your browser tab.
Step 3
Download the merged PDF. Nothing was uploaded, and nothing is stored.
Your file never leaves your browser
Everything this tool does happens in your browser tab. The PDF is opened, processed, and rebuilt by code running on your own device — it is never uploaded, so there is no server copy, no retention policy to read, and nothing to breach. Close the tab and it is gone.
Frequently asked questions
Is this PDF merger really free?
Yes — completely. No account, no watermark, no page limits, no trial countdown. The merge runs as code in your browser tab, so it costs us almost nothing to offer, and we make our money on our paid bank-statement converter instead.
Do my PDF files get uploaded to a server?
No. Your PDFs are read, combined, and written back out by JavaScript running in this tab. The only network traffic is this page's own code and an anonymous count of how often the tool gets used — never a byte of your files, which we could not read if we wanted to.
Can I change the order of the merged files?
Yes. Each file in the list has up and down arrows — put them in the order you want before you click Merge. The merged PDF follows that order exactly, and you can reshuffle and merge again as many times as you like.
Is there a limit on file size or number of files?
There is no limit on how many PDFs you add. Each individual file has to be under 100 MB, which is a guard against the browser tab running out of memory. Very large merges are limited by your device's memory, not by us.
Why does my password-protected PDF fail?
An encrypted PDF cannot be read without its password, and this tool never asks you for one. Open the file in your usual PDF reader, remove the protection or save an unprotected copy, then merge that. You get a clear error rather than a silent failure.
