Blur Image Online Free
Hide faces, text or other sensitive details by selecting an area manually. Choose blur or pixelation and control the effect strength.
How to blur part of an image

- Drag over the area you want to hide and choose blur or pixelation.
- Apply the effect, review the image and export it.
Manual privacy control
You decide exactly which rectangular area is affected. Applied blur and pixelation become part of the working image and are included in the exported file.
Blur or pixelate?
Blur is useful when you want a softer visual treatment, while pixelation creates a blockier mask that can make details harder to read at a glance. Increase the strength until the sensitive detail is no longer recognizable at the size you plan to share.
Check sensitive information before sharing
Visual obscuring is not the same as cryptographic redaction. For highly sensitive text, account numbers or documents, use a strong effect, review the exported image at full size and avoid sharing the original file.
