Frequently Asked Questions

Why not promise full sanitization?

PDFs can contain hidden objects, attachments, scripts, layers, and incremental updates. This browser tool targets standard metadata and simple action entries, then flags markers that may need deeper review.

Will visible text or images change?

No. The tool saves the existing PDF content while changing metadata fields. Use Redact PDF when visible content must be permanently covered.

Should I sanitize before external sharing?

Yes for routine office sharing. For regulated, legal, or highly confidential files, also review the document with your required compliance tools.
