常见问题
It strips author info, creation and modification dates, software details, comments, annotations, form field data, JavaScript, embedded files, and other hidden content. Everything you can see on the page stays, while the invisible metadata and scripts are cleaned out.
No. The process preserves all visible content, text, images, and formatting exactly as they appear. Only hidden and potentially sensitive data is removed, so the cleaned PDF looks identical while carrying none of the underlying metadata.
Hidden metadata can leak your name, the software you used, edit history, or embedded scripts to anyone who opens the file. Sanitizing prevents that information leakage, which matters when publishing documents or submitting them to third parties.
Yes. Beyond metadata, the tool removes embedded JavaScript, attached files, and other potentially unsafe content, making the resulting PDF cleaner and safer to distribute, not just stripped of authorship details.
Completely. All cleaning happens locally in your browser, so your document never leaves your device. That's especially fitting for a privacy tool, since your file isn't uploaded anywhere while its hidden data is being removed.
