Image Blur Tool
Blur or pixelate a specific area of a photo — hide a face, license plate, or personal info before sharing it.
How to Blur Part of a Photo
- Click the upload area or drag in a JPG, PNG, or WebP image.
- Click and drag directly on the image to draw a rectangle over the area you want to hide.
- Choose Blur or Pixelate, and adjust the strength slider to your liking.
- Draw more regions if needed, remove any from the list, then click "Download Image" to save the result.
Frequently Asked Questions
What's the difference between Blur and Pixelate mode?
Blur applies a smooth Gaussian-style blur filter to the selected region, which softens details but can sometimes still be partially reversed with sharpening tools. Pixelate downsamples the region to a handful of large blocks and scales it back up with smoothing turned off, permanently destroying the fine detail - it's the blockier, more thorough option for hiding text or faces.
Can I blur more than one area in the same photo?
Yes - draw as many rectangular regions as you need by clicking and dragging on the image, and remove any of them individually from the region list before downloading.
Is the blurred or pixelated pixel data actually changed, or is it just a visual overlay?
The pixel data is genuinely changed. Blur mode redraws the image through a canvas blur filter clipped to your region, and pixelate mode downsamples that region to a tiny canvas and draws it back up with image smoothing disabled - both permanently alter the exported pixels rather than placing a shape on top.
How do I control how strong the effect is?
Use the strength slider - in Blur mode it sets the blur radius in pixels, and in Pixelate mode it sets the block size, so a higher value produces bigger, blockier squares.
Is my photo uploaded to blur or pixelate it?
No. Every effect is computed locally with the Canvas API in your browser tab - your photo never leaves your device.
