Merge PDF

Combine multiple PDFs into one document, entirely in your browser. Your files are never uploaded.

The interactive merge tool is arriving with the next site update. This page will hold it — until then, here is exactly how it will work.

How it will work

  1. Drop two or more PDF files onto the work area.
  2. Drag them into the order you want.
  3. Press Merge — the combined PDF is built on your device and saved as merged.pdf.

Merge PDF FAQ

Are my files uploaded anywhere?

No. Merging happens inside your browser tab. This page has no upload endpoint — you can confirm in DevTools → Network that no request carries your files.

Is there a file size or page limit?

The browser tools accept files up to 100 MB. Larger files get a clear message instead of a silent failure — the Android app handles bigger documents.

Does merging change my PDFs?

Your original files are never modified. The tool reads them, builds a new combined PDF, and leaves the originals exactly as they were.
