NanoImage is a free image blurring tool that lets you blur images online — blur part of an image, hide faces, cover license plates, redact sensitive text, or apply a background blur effect. Everything runs in your browser with no server upload and no account required, so you can blur photos privately before sharing.
Common targets include faces, license plates, street addresses, usernames, chat screenshots, IDs, and other private details. Use the brush to blur only the regions you need while keeping the rest of the photo sharp. Adjust Gaussian blur, soft blur, or background blur strength until sensitive information is unreadable.
Protect identity in screenshots before posting on social media, redact personal information in legal or HR documents, hide confidential data in bug reports and support tickets, or blur backgrounds for a cleaner professional portrait. A browser-based image blur effect is faster than desktop software when you only need selective blur online — no install, no signup.
Blur softens details with a smooth image blurring effect; pixelate uses blocky mosaic for stronger anonymization. For hidden metadata (GPS, camera model), remove EXIF before publishing. Many users combine blur faces or blur license plates with EXIF removal for safer sharing.
For stronger anonymization, try our Pixelate Image tool. To remove hidden GPS and camera metadata before sharing, use Remove EXIF Data — both run locally in your browser like this blur tool.
Upload your photo, select the brush tool, paint over the area you want to blur, adjust blur strength, and click Download. You can blur any specific region, object, or person in your image.
