Your files never leave your device
This tool runs entirely in your browser. Nothing is uploaded to a server, so your documents and photos stay private. It is free, has no watermark and needs no sign-up.
Frequently asked questions
Is merging PDFs here really free?
Yes. There is no sign-up, no watermark and no limit on how often you use it.
Are my PDFs uploaded to a server?
No. The merge happens inside your browser, on your own phone or computer. The files never leave your device.
Can I change the order of the files?
Yes. Use the up and down buttons on a phone, or drag a file on a computer. The merged PDF follows the list from top to bottom.
Will merging lower the quality?
No. Pages are copied as they are, so text, images and layout stay the same.
What if one PDF is password-protected?
Protected PDFs cannot be read in the browser. Remove the password first with the app that created the file, then add it again.
Is there a maximum number of files or pages?
There is no fixed limit. The real limit is your device memory, so very large files may be slow on an older phone.
