What Sanitize PDF does
Free Sanitize PDF. Create a clean copy with metadata, JavaScript and other extras stripped for safer sharing. Runs 100% in your browser — no file uploads, no account required, no watermark added. Free and unlimited on PDFStudio Pro.
Sanitize PDF focuses on access control — passwords, permissions or unlocking files you are allowed to open.
How to use Sanitize PDF
- Upload the PDF.
- Click Sanitize.
- Download the clean PDF.
Practical examples
- Run Sanitize PDF when you need a quick result without installing desktop software.
- Use Sanitize PDF on a shared computer — nothing stays after you close the tab.
- Process a sanitize-related task privately in the browser and download only the output.
Tips for better results
- Prefer the original PDF when possible; re-saving multiple times can degrade image-heavy files.
- If a file fails, try a smaller range of pages or a single file first to isolate the issue.
- Keep a copy of the source file until you have checked the download.
Privacy and limits
PDFStudio Pro is built so core tools can run in your browser. That means the file you select is handled in the current tab whenever the tool supports local processing. Very large files depend on your device memory. After you download the result, close the tab if you do not want the data kept in memory.
