What the Image Blur Tool does

Apply a controlled blur to an image for privacy masking, backgrounds, or creative effects.

Soften an image or just part of it, for privacy masking, backgrounds, or effect.

Why the Image Blur Tool is useful

A blur can soften distracting areas or obscure sensitive visual details before sharing.

Blurring a face or license plate before sharing a photo is basic courtesy and often a legal need, and a full editor is more tool than the job needs.

Also known as: blur image, image blur, gaussian blur, free image blur tool, online image blur tool, image blur tool online free, image blur tool tool.

Selective blur leaves the rest of the photo untouched.

Real-life use cases

Privacy masking

Mask bystanders' faces in a street photo before posting it.

Tips for the best results

A light blur may not reliably conceal sensitive text; use opaque redaction for private information.
Blur slightly beyond the edges of what you are hiding; recognizable shapes peek out otherwise.

Conclusion

View the saved image at full size once, since light blur that looks safe when small can sometimes be reversed by zooming.
