You give
Two or more PDF files (up to 100 MB each)
You get
One PDF containing every page of every file, in your order
Good to know
Works best with files under 100 MB (the upload cap); very large files depend on your device's memory. Bookmarks (outlines) and fillable form fields from the source files are not carried over; page content, links on pages and page sizes are. Password-protected or permission-locked PDFs can't be edited: make an unlocked copy first (open it with the password and use Print → Save as PDF).
Privacy

FAQ

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

No fixed limit. Each file can be up to 100 MB; the practical ceiling is your device's memory, so dozens of typical documents merge without trouble.

Will merging reduce the quality of my PDFs?

No. Pages are copied as-is — text stays selectable and images keep their original resolution. Nothing is re-rendered.

Are my files uploaded to a server?

No. Merging happens in your browser with JavaScript, so the documents never leave your computer or phone.
