Merged on your device — never uploaded

Merge PDF Files

Combine contracts, scans and reports into a single PDF — in the order you choose. Unlike typical "free PDF sites", your documents are merged on your device and never uploaded.

How it works

  1. Add your PDFsDrop several files at once or add them one by one — they stay in your browser's memory.
  2. Arrange the orderMove files up and down until the order is right.
  3. Merge and downloadOne click produces a single PDF with all pages in your chosen order.

Why merging PDFs locally matters

Think about what people merge: signed contracts, scanned passports and IDs, medical results, invoices, court documents. Now think about the standard "free PDF merger" workflow — uploading exactly those files to an unknown company's server and trusting a "we delete your files" promise you can't verify.

This tool removes the trust question entirely. The merging happens inside your browser using an open-source PDF engine: pages are copied from your source files into a new document right in memory, and the result is saved back to your device. No upload, no queue, no size games — a 100 MB scan pack merges as fast as your computer allows.

All pages keep their original quality and dimensions — nothing is re-compressed or rasterized. Mixed page sizes (A4 + letter + scans) are preserved as-is.

Frequently asked questions

Is there a limit on file count or size?
No artificial limits — merge as many PDFs as your device's memory allows. Hundreds of pages are no problem on a normal laptop.
Are password-protected PDFs supported?
Files that require a password to open cannot be merged — remove the password first. Files with only editing restrictions usually merge fine.
Does it keep quality?
Yes — pages are copied, not re-rendered. Text stays selectable, images keep their original resolution.
