What this removes
- Embedded JavaScript that could run when the PDF is opened
- Auto-open and auto-run actions
- Document-level file attachments
- Title, author, and other metadata
A PDF from an untrusted source can carry a hidden script or attachment you don't want. Sanitizing strips that content before you open or share the file further.
Your file is processed only in this browser tab — nothing is uploaded.
Private by design. Strip embedded JavaScript, file attachments, and other hidden content that could carry risk before you share a PDF. Your file is processed entirely in this browser tab using WebAssembly — it is never uploaded anywhere, so it stays yours even on a shared or offline computer.
Frequently asked questions

- Embedded JavaScript, auto-open or auto-run actions, document-level file attachments, and metadata like title and author.
- Why does this matter?
- A PDF from an untrusted source can carry a hidden script or attachment that runs or opens without your knowledge. Sanitizing strips it out before you share or open the file further.

- No. Everything runs locally in this browser tab — your file is never sent anywhere.
