Blur Image
Blur a whole image or a chosen area with adjustable intensity — JPG, PNG and WebP, in your browser.
Blur a whole photo or just a selected region — faces, license plates or any sensitive detail — with an adjustable slider. Everything runs in your browser on the Canvas API, so nothing is ever uploaded.

Privacy and security
Limitations
- Blurring is pixel-based and applies a fixed-radius gaussian blur — suitable for most redaction needs but not for legally mandated secure erasure.
- Works on JPG, PNG and WebP only.
- Max file size 20MB. Very large images are scaled down for the preview but processed at full resolution, so may take a moment.
- PNG transparency is preserved on output; JPG output fills transparent areas with white.

Frequently Asked Questions
Is it safe to blur sensitive photos here?
Yes — blurring runs entirely in your browser using the Canvas API. Your photo is never uploaded to any server, which is exactly what you want when redacting private details.
Can I blur just part of an image?
Yes. Choose 'Selected region', then drag the box over the face, license plate or detail you want hidden and pull its corner handles to fit. Only that area is blurred; the rest stays sharp.
How strong should the blur be for redaction?
Use a high intensity (20px or more) when something must stay unreadable — faces, plates, documents. A light blur still leaves shapes readable, so preview at full size before sharing.
Which formats can I blur?
JPG/JPEG, PNG and WebP files up to 20MB. The result downloads in the same format as the original.
Do I need to install anything?
No — everything runs in your browser. Drop in an image, pick whole-photo or region blur, adjust the slider and download.
