Merge PDF Files Into One
Combine reports, invoices, chapters, and scans into a single tidy PDF — in exactly the order you want.
Scattered documents waste everyone's time: five invoice PDFs here, three contract drafts there, a cover page that needs to go first. PDFClaws's Merge PDF tool stitches them all into one clean file in seconds.
Drag & drop your PDFs into the perfect order, preview each file, and merge with a click. There's no page limit and no file size cap — combine a 2-page letter with a 400-page manual if you like.
And because merging runs 100% locally, your documents are never uploaded. That makes PDFClaws ideal for combining confidential business files, legal bundles, and personal records.

FAQ
Merge PDF FAQ
Is there a limit to how many PDFs I can merge?
No. Merge two files or two hundred — PDFClaws has no page, count, or size limits because everything runs on your own hardware.
Will merging reduce the quality of my documents?
Never. Merging copies the original pages into the new file without re-encoding, so text, images, and vector graphics stay exactly as they were.
Can I control the order of pages in the merged PDF?
Yes. Files are merged in the order shown in the list — just drag them into place before clicking Merge.
Can I merge password-protected PDFs?
Unlock them first with the built-in Decrypt PDF tool (you'll need the password), then merge the unlocked copies.
