Mask Document Online
The safest approach for "mask document online" is to run one consistent process every time you post.
What needs to be hidden
For mask document online, 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.
Step-by-step workflow
- Upload the image 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.
Recommended blur and masking settings
- 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.
- For listing photos, verify thumbnails and mobile crops before publishing.
- Make the mask slightly larger than the object so cropped versions stay safe.
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
Example scenario
In a typical "mask document online" task, the first pass handles the visible target and the second pass checks reflections and crops.

Last-mile quality review
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.
- Review reflective surfaces, including windows, paint, and mirrors.
- Keep one checklist for all team members so quality remains consistent.
- Check thumbnail and compressed preview versions, not just the full file.
