Blur Image

Apply a blur to whole images or sensitive spots for softer backgrounds and lighter redaction.

Blur softens detail instead of replacing it with mosaic blocks. Creators use it for background defocus effects; privacy-minded users use it to obscure documents and faces in screenshots.

Heavy Gaussian-style blur is harder to read but not always harder to reverse than a strong mosaic. For secrets, prefer cropping out the region or combining blur with mosaic. Always keep unshared originals separate.

After redaction, compressors can shrink the export for chat apps. Color-picker helps pull brand colors from the unblurred areas of a design.

How to use

Upload your image — Choose the photo or screenshot to edit.
Decide full-frame vs region — Blur everything for an artistic soft look, or paint only sensitive zones.
Adjust blur radius — Increase until text or faces are unreadable when privacy is the goal.
Preview carefully — Check edges of the blurred mask for leftover readable pixels.
Download the result — Export the blurred derivative for posts, tickets, or mockups.

Use cases

Background soft focus — Make a subject stand out in a quick social crop.
Document redaction — Obscure account numbers on receipts before sending to a vendor.
UI mock storytelling — Hide unfinished screen areas while sharing a concept.

Tips

For legal-grade redaction, remove pixels (crop/black box) rather than relying on light blur.
Zoom to 100% before declaring text unreadable.
Artistic blur on portraits still needs consent when faces remain identifiable.
Pair with mosaic-image when you want a clearer “censored” signal.

FAQ

Is blur enough for secrets?

Not always. Use strong settings or remove the content entirely for highly sensitive data.

Does editing stay in the browser?

Yes—processing is designed to be local to your session.

Can I undo after download?

Keep the original file. The download is a baked-in derivative.

Whole image only?

Region tools may be available depending on the UI—use them for selective privacy blurs.

Quality loss elsewhere?

Unblurred regions should remain intact aside from re-encoding on export.
