Everyday uses

Common uses.

Join separate PDFs — IDs, certificates, letters, forms — into one file for uploads that ask for a single combined document. Drag the files into the order you want, then download. They're merged on your device, never sent to a server.

What makes it different

Built for real needs.

🎯

Drag to reorder before merging

Arrange your PDFs in the exact order you want. First one loaded ≠ first in the output.

∞

No page or file cap

Merge as many PDFs as your device can handle. No 20-page-per-day limit.

📝

Text stays selectable

Merged PDF keeps every character copyable, not flattened to images.

🔒

100% in-browser

Your PDFs never leave your device — the merge happens locally in your browser.

Good to Know

Common questions.

How many PDFs can I merge?

As many as your browser memory can hold — typically dozens of normal-size PDFs without trouble.

Is this free and watermark-free?

Yes. No sign up, no watermark, and the merged PDF is exactly your originals stitched together.

Are my files uploaded?

No. The merge happens entirely in your browser using the open-source pdf-lib library. Files never leave your device.

Will bookmarks or links survive?

Pages, text and embedded images are preserved exactly. Some PDF metadata and bookmarks may not carry over from every PDF.
