Compress and Password-Protect PDF

Shrink a PDF, then lock it with an AES-256 password, in one private browser workflow with a single download. No upload, no account.

Multi-step browser workflow

Shrink a PDF, then lock it with an AES-256 password, in one private browser workflow with a single download. PaperKit runs each step locally in the browser and passes the output to the next step.

Included steps

  1. Compress PDF — Shrink a PDF by re-encoding the photos and scans inside it at the quality you choose, or fit it under 100 KB, 500 KB or 1 MB, all in your browser.
  2. Protect PDF — Add a password to a PDF with AES-256 encryption, and optionally block printing or copying, entirely in your browser.
