Where your files are processed

Clear information about what happens to your document before you begin.

Local processing — the default

Merging, splitting, compressing, rotating, signing, converting, password work, and redaction run entirely inside your browser.

  • Your files are never uploaded, stored, or logged.
  • Cached tools continue working offline.
  • No account, watermark, or queue.

Cloud assisted — only with consent

A small number of features need a connection. They ask first and show exactly what will be shared.

  • AI tools send extracted text only after you opt in, never the raw PDF.
  • P2P sharing connects directly to a recipient you choose.
  • Network and account requirements are shown before you begin.
