PDF Merge

Combine several PDFs into one document without uploading anything. Add the files, drag them into the order you want using the arrow buttons, and merge.

How to use the PDF Merge

  1. Add two or more PDFs.
  2. Reorder or remove files.
  3. Click Merge and download.

How it works

The merge happens locally using a PDF library in your browser, so confidential documents stay on your device. Password-protected PDFs cannot be merged until unlocked.

Good to know

Files up to 50 MB each are supported; very large files depend on your device memory.

Frequently asked questions

The file may be encrypted or corrupted.
