Blur or Pixelate an Image online, free
Sometimes you need to share an image but hide part of it — a face, a home address, a bank detail or a number plate. This free tool pixelates any region you choose, right in your browser. Draw a box over the sensitive area, set how strong the effect should be, and apply. Because nothing is uploaded, sensitive images never leave your device — which matters most for exactly this kind of redaction.
How to blur an image
- Upload your image, or drag and drop it onto the editor.
- The Blur tool is ready — drag the box over the area you want to hide.
- Adjust the strength slider for a lighter or heavier effect.
- Click Apply to pixelate that area.
- Choose a format and click Download.
Frequently asked questions
Can I blur more than one area?
Yes. Apply the effect to one area, then click New box and repeat for the next area as many times as you need.
Can the blur be reversed by someone else?
Pixelation replaces the underlying pixels, so a strong setting is not simply undoable. For sensitive data, use a high strength.
Is my image uploaded anywhere?
No. Everything happens locally in your browser — ideal when the image contains private information.
