How it works

Combine PDFs without sending the document to a processing server.

Choose two or more ordinary PDF files, set their order, then merge and verify the result in this browser. Complex PDF structures may be refused rather than silently simplified.

  1. Choose two or more PDF files.
  2. Put the files in the order you want.
  3. Merge and verify the output, then download the result.
Before you share

A little clarity
goes a long way.

Inspect common document properties before sending.
