Join PDF Files Into One Document
Package several PDF files into a single attachment for email, submission, or filing.
Application packets, tender submissions, and internal reports often need to arrive as one file even though they're produced by several people or systems. This tool joins any number of separate PDF files — cover letters, spreadsheets exported as PDF, signed forms — into a single document ready to attach and send.
Upload each file, put them in the order the reader should see them using the up and down arrows, then generate the joined PDF. Because the whole process runs locally in your browser instead of on a remote server, there's no wait for an upload and no third party ever handling your paperwork.
It's a good fit for HR packets, vendor submission bundles, and any workflow where a recipient expects "one attachment, not five." If the joined file ends up too large for an email attachment, our Compress PDF tool can shrink it afterward.
Frequently asked questions
Does joining files preserve the original page order within each PDF?
Yes. Each source file's internal page order is kept exactly as-is; you only control the order of the files relative to each other.
Can I join more than a couple of files at once?
Yes, there's no fixed limit on the number of files you can join in one go.
Will the joined file be too large to email?
It depends on your source files' sizes, since joining doesn't compress anything. If the result is too large, try our Compress PDF tool afterward.
Do I need to sign up or install anything?
No. There's no account, no browser extension, and no software to install — it runs directly on this page.
