What is PDF Sanitizer?
PDF Sanitizer removes potentially harmful or unnecessary elements from a PDF — metadata, annotations, JavaScript, embedded files, links, structure trees, and mark info — in a single pass. It offers three severity levels: Standard, Deep, and Maximum, each removing progressively more elements.
The tool uses pdf-lib to flatten forms, clear metadata, strip annotations, remove JavaScript actions, delete embedded files, and optionally remove links and structure trees. The result is a leaner, safer document suitable for archival or external sharing.
How to Use PDF Sanitizer
- Upload a PDF by dropping it onto the upload zone.
- Choose a sanitization level: Standard (recommended), Deep (removes links and structure), or Maximum (removes all removable elements).
- Click Sanitize. The tool processes every page, removing elements at your chosen level.
- Download the result as
sanitized.pdf.
Why Use PDF Sanitizer?
PDFs can contain hidden risks — JavaScript that executes on open, embedded files that carry malware, metadata that leaks author information, and annotations that reveal internal comments. Sanitizing a document before publishing, emailing, or archiving removes these risks in one step. It is standard practice in legal, healthcare, and government workflows where document integrity and safety are critical.
Privacy & Security
Your files never leave your browser. The sanitization happens entirely on your device. Nothing is uploaded to Racira's servers, no copies are stored in the cloud, and no file data is transmitted at any point.
Frequently Asked Questions
What does each level remove?
Standard: metadata, annotations, JavaScript, embedded files, and forms. Deep: everything in Standard plus links and structure trees. Maximum: everything in Deep plus mark info and any other removable metadata.
Does this affect the visual content?
No. Only metadata, annotations, and interactive elements are removed. Text, images, and vector graphics on the page content layer are preserved exactly.
