Is merging PDFs free?

Yes. Merging happens in your browser, with no credits and no account required.

Are my PDFs uploaded to a server?

No. The files are joined locally on your device and never leave it.

Can I change the order of files before merging?

Yes. Use the move up and move down buttons to arrange the files, then merge.

Why does a file fail to open?

A damaged or password-protected PDF cannot be merged. Remove it from the list or remove the password first.

Do I need an account to use it?

No. This tool is free for everyone and works without signing in.

How it works

Merge PDF files online free - no sign up, no registration and no file size limits. Combine scanned chapters into a single book, a month of invoices into one file, or a contract with all its annexes in the order you set.

Drop up to 20 PDF files onto the page, or click to browse for them. A fully encrypted PDF has to be unlocked first - use the Unlock PDF tool, then come back.
Check the numbered list: it is the exact order the pages will follow in the result. The arrows next to each file move it up or down, and the cross removes a file you added by mistake.
Add more files at any time - the order you already set stays as it is. Twenty files is the limit, and the drop area goes away once you reach it.
Press “Merge PDFs” and download the combined document.
