Questions & answers
How many PDFs can I merge at once?
There is no fixed limit. Dozens of files work fine; very large sets depend on your device memory.
Will bookmarks and links be kept?
Page content, text and images are kept exactly. Bookmarks from the separate files are not combined into the new outline.
Is Merge PDF free?
Yes. Every tool on this site is free to use, with no signup, no watermark and no daily limit.
Are my files uploaded to a server?
No. Your files are processed inside your own browser on your device. They are never uploaded, so nobody else can see them.
Is there a file size limit?
There is no fixed limit. Because processing happens on your device, very large files depend on your phone or computer memory. Most files up to a few hundred MB work fine.
Does it work with password-protected PDFs?
Yes. If a PDF needs a password to open, the tool asks for it and then works normally. The password never leaves your browser.
Does it work on mobile?
Yes. It works in Chrome, Safari, Edge and Firefox on Android, iPhone, Windows and Mac.
