Merge PDF

Combine PDFs into one file

Select two or more PDF files and merge them into a single document, in the order you chose. It's perfect for combining scanned pages, bundling reports, or stitching together chapters. The whole process runs in your browser using your own device's processing — your documents are never uploaded to any server, which matters for anything private.

How to use it

• Click "Choose PDF files" and select all the PDFs at once.
• They'll be merged in the order they appear in the list.
• Click "Merge PDFs" and the combined file downloads automatically.

FAQ

Is there a file-size or page limit?

There's no fixed limit, but because everything is processed in your browser's memory, very large files (hundreds of MB) may be slow on older devices. For typical documents it's fast.

Can it merge password-protected PDFs?

No — encrypted PDFs can't be merged until they're unlocked. You'll get an error if a selected file is protected.

Is the PDF merger free to use?

Yes, it's completely free with no sign-up, no watermark added to the output, and no daily limit on how many files you can merge.

Are my PDFs uploaded to a server?

No. The merge happens entirely in your browser using your device's own processing, so your documents never leave your computer. That makes it safe for confidential contracts, records, and scans.

How do I change the order of the merged files?

Files are combined in the order they appear in the list, which follows the order you selected them. To get a specific sequence, select the files in the order you want them, or pick them one at a time.

Does it work on mobile?

Yes. You can select PDFs and merge them on a phone or tablet, though very large files may process more slowly on mobile hardware than on a desktop.
