To merge PDFs, drop every file in, drag the thumbnails into the order you want, then click merge and download the combined document. Pages are copied across intact, so text stays selectable and images keep their original resolution. There is no file count limit and no watermark on the output.

Combine any number of PDFs into a single document. Drag the files into the order you want and download the merged result — no page limit, no watermark.
How to use Merge PDF Files
Select your PDFs — Drop in every PDF you want to combine. They appear as thumbnails in the order added.
Arrange the order — Drag the thumbnails until the sequence matches the document you want.
Merge and download — Click merge and save the combined PDF to your device.
Why use this tool
Drag to reorder — Arrange documents visually before merging instead of guessing at the final sequence.
No file count limit — Merge two documents or fifty; the only constraint is your device memory.
Bookmarks preserved — Existing page structure and text remain selectable and searchable in the merged file.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
We impose no limit. Very large merges — hundreds of megabytes — depend on how much memory your browser can allocate, which is generally several hundred megabytes.
Will merging reduce quality?
No. Pages are copied across intact, so text stays selectable and images keep their original resolution.
Can I merge password-protected PDFs?
Remove the password first with the Unlock PDF tool, then merge. Encrypted files cannot be read until they are decrypted.
Are my files uploaded to a server?
No. Every conversion runs inside your own browser using JavaScript and WebAssembly. Your files never leave your device, which means there is nothing for us to store, read, or leak.
