How do I hide a document safely?

Draw a manual mask, increase padding so crops stay covered, and verify the result in the final share format.

Does this work on screenshots?

Yes. BlurFaces handles screenshots and photos, and manual rectangles are ideal for UI elements and documents.

Should I blur or fully redact sensitive details?

For public-facing posts, strong blur is usually enough. For compliance evidence or legal records, hard redaction may be safer.

Can I hide multiple details in one image?

Yes. Add as many manual masks as needed for screens, badges, addresses, receipts, or documents.

What needs to be hidden

For cover document before posting, the risk is usually not aesthetic. It is a specific identity signal such as a document, address, document, or screen that gives away more than the rest of the image should.

Operational sequence

Upload the photo to BlurFaces.
Draw a manual rectangle over the document or any other sensitive region.
Increase padding and blur until text and key shapes are no longer readable.
Export and review the exact crop or layout that will be shared publicly.

Settings that work best

Make the mask slightly larger than the object so cropped versions stay safe.
For screenshots, review notification previews and side panels, not just the center content.
If the detail contains dense text, raise blur strength until individual characters lose edge definition.
Check for the same detail appearing twice, such as a badge plus its reflection.

Where people usually miss leaks

Secondary screens in the background
Badges or documents on desks
Addresses, labels, and QR codes near the edge of the frame

Final checks before you publish

Most privacy misses happen in the final 10%: compressed previews, reflected details, or crop variants. Treat verification as part of the workflow, not an optional step.

Open the final photo in full-screen and confirm identifiers are unreadable.
Review reflective surfaces, including windows, paint, and mirrors.
Keep one checklist for all team members so quality remains consistent.
