Sanitize PDF
Strip malicious JavaScript and embedded files from a PDF to make it safe to share. Server-side security cleaning — free.
What is Sanitize PDF?
Sanitizing a PDF removes potentially dangerous content — embedded JavaScript, action triggers, and embedded files — that could execute when the document is opened, while keeping the visible text, images, and layout completely intact. This is the standard security step before opening a PDF from an untrusted source or sharing one widely, because a malicious PDF can carry code that runs in certain viewers. NewKitApp performs this cleaning server-side using a hardened engine that strips the risky objects without altering what you actually see on the page. The result is a functionally identical PDF that's far safer to distribute.
How to Use Sanitize PDF
- Drag your PDF onto the dropzone, or click to choose a file.
- Click Sanitize. JavaScript and embedded files are stripped from the document.
- Download the cleaned PDF — it will look identical but carry no active code.
- The download link expires in about 10 minutes and the file is deleted after processing.
Examples
Safe-to-share form
Input: PDF downloaded from an unfamiliar site
Output: Same-looking PDF with JavaScript and embedded files removed
Cleaned attachment
Input: PDF with auto-run scripts
Output: Inert PDF safe to email and archive
Common Mistakes
- Confusing sanitizing with password removal — they're different; sanitize strips code, unlock removes passwords.
- Expecting the visible content to change — sanitization is invisible by design.
- Forgetting that a sanitized PDF can still be password-protected if it was before.
Why Use This Tool
- Removes the active content that makes untrusted PDFs risky.
- Your visible document stays exactly the same.
- Server-side cleaning is more thorough than browser-based alternatives.
- Free and private — files are deleted right after processing.
