Sanitize PDF Online Free: Strip Scripts & Links
Strip JavaScript, auto-run actions, embedded files, and external links from a PDF for safe sharing.
PDFs can carry active content: JavaScript that runs when the file opens, embedded file attachments, and links that point to external sites. Sanitize PDF strips these before you share a file with clients, upload it to a portal, or archive it. Form fields and their values are kept. Only the scripts attached to them are removed.
How to Use It
- Upload your PDF and wait for the local preview to load.
- Adjust the settings: Adjust the available settings and run the tool locally in your browser.
- Download the result: Download the processed file directly to your device.
Frequently Asked Questions
What exactly does sanitizing remove?
Document-open JavaScript, auto-run actions on the document and its pages, the document JavaScript name tree, embedded file attachments (including file-attachment annotations), external URI link annotations, and scripts attached to form fields. Visible page content, internal navigation links, and bookmarks are untouched.
Will my form fields or their values be affected?
No. The form-scripts option deletes only the validation, formatting, and calculation actions attached to fields. The fields themselves, their current values, and their appearance stay exactly as they are.
What happens if the PDF is already clean?
The tool still exports a re-saved copy. Zero removals is a valid result. It means the file contained no active content, and the download is a verified-clean copy you can share with confidence.
Is my PDF uploaded anywhere?
No. Sanitize PDF runs entirely in your browser using pdf-lib. For supported workflows, file contents are not uploaded for processing; site analytics and the assistant are separate.
