Zero upload · Browser-local · No watermark

Merge PDFs into one.

Drop or pick several PDF files, arrange them in the order you want, and combine them into a single document — entirely in your browser. Nothing uploaded.

Why merge here

Private, ordered, and unlimited.

01

Nothing uploads

Your PDFs are combined in your browser via pdf-lib. Open the devtools Network tab to verify — zero outbound file requests. Ideal for confidential documents.

02

Reorder freely

Arrange documents before merging. Move any file up or down and the merged PDF follows your order exactly.

03

No file cap

Merge as many PDFs as your device can hold — no 2-file free limit and no daily quota like upload-based services.

Frequently Asked Questions

No. Merging runs entirely in your browser using pdf-lib. Open the Network tab in devtools while merging — zero outbound traffic. Your files never leave your device, which is ideal for contracts and other confidential documents.
Yes. The merged PDF follows the order shown in the list. Use the ↑ and ↓ buttons to rearrange, or remove any file, before you press Merge PDF.
There is no artificial paywall. You can merge up to 50 PDFs per run, bounded only by your device memory — not by a 2-file free cap like many upload-based tools.
Encrypted PDFs cannot be read without the password and are skipped with an error. Remove the password in your PDF viewer first, then merge.
No. Pages are copied byte-for-byte into the new document, so text stays selectable and images keep their original resolution. Merging never re-compresses your content.
