Questions about Merge PDF
Quick answers about privacy, limits and results. Need more help? Contact us.
Is there a limit on how many PDFs I can merge?
There is no fixed file count. The practical limit is your device memory, so dozens of normal documents merge without trouble.
Will bookmarks and links survive?
Page content, images and text are kept exactly. Document-level bookmarks from the source files are not carried over.
Are my files uploaded to your server?
No. This tool runs entirely in your browser, so your files never leave your device.
Is it free?
Yes. Every browser tool is free to use without sign-up or watermarks.
