Tools › PDF tools › PDF Merge
Combine multiple PDF files into a single PDF, in the order you choose. Your files are never uploaded — merging happens entirely in your browser.
Your PDFs are never sent to a server (merged in your browser)
How to use
- Choose the PDFs you want to merge (multiple allowed, and you can add more afterward).
- Use the ↑↓ buttons to set the merge order, and ✕ to remove files you don't need.
- Press "Merge and download" to save the combined PDF.
Pages are copied as-is
This tool copies each page from your PDFs directly into a new combined PDF, rather than re-rendering them as images. That means if the original text was selectable and searchable, it stays that way after merging.
Use it to combine invoices, quotes or contracts into a single submission, or to bundle scanned documents into one file. Password-protected PDFs may fail to load.
FAQ
Are my PDFs uploaded to a server?
No. Loading, merging and saving all happen entirely inside your browser.
How is the merge order decided?
Files merge in the order shown in the list, top to bottom. The initial order matches your selection order — use the ↑↓ buttons to rearrange as needed.
Can I merge password-protected PDFs?
Not currently. If a file fails to load, that will be shown — please remove the password first using another tool.
It says the file couldn't be loaded, but it isn't password-protected.
On Windows, files downloaded from the internet are sometimes automatically flagged as blocked (right-click the file → Properties, and you'll see a note like "This file came from another computer and might be blocked"). If so, checking "Unblock" in the Properties dialog and clicking OK often resolves it.
Is there a limit to how many files I can merge?
No hard limit, but more files and pages use more of your browser's memory. For very large merges, a PC is recommended.
