About this tool
Combines multiple PDF files into one, in whatever order you choose, entirely in your browser using pdf-lib — your files are never uploaded to a server, unlike most free "merge PDF" tools online.
Frequently asked questions
Does merging preserve the original formatting and images?
Yes — pages are copied as complete, self-contained objects rather than re-rendered, so text, images, fonts, and layout come through exactly as they were in the source files.
Can I merge password-protected PDFs?
Not currently — an encrypted PDF can't be read without its password, and this tool doesn't have a way to enter one. Remove the password from the file first using whatever tool originally protected it.
