Frequently Asked Questions

How do I combine PDF files into one?

Add two or more PDFs, drag them into the order you want (or use the arrows), and click Merge PDFs. The combined file downloads immediately, with each document's pages in the order you chose.

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

There is no fixed limit on the number of files. Each file can be up to 100 MB, and the practical ceiling is your device's memory. Merging dozens of files is no problem on a typical laptop or phone.

Will the merged PDF lose quality?

No. Pages are copied as they are, without re-compressing images or re-rendering text, so the merged PDF looks exactly like the originals.

Can I merge password-protected PDFs?

Encrypted PDFs need to be unlocked first. Use our free Remove PDF Password tool (leave the password empty if the file opens without one but has restrictions), then add the unlocked file here.

Are my files uploaded?

No. Merging happens entirely in your browser, so your documents never leave your device.

Are bookmarks and form fields kept?

Page content, text, images and links on each page are kept. Bookmarks (the outline panel) and fillable form fields from the source files are not carried over into the merged document.
