Blur an image with adjustable strength

For creators protecting information, calming a distracting background or preparing a sense of depth.

Blur your image at an adjustable strength and get a result that hides sensitive detail, quiets a busy background or softens harsh edges.

How to use

  1. Add a PNG, JPEG or WebP image that does not exceed 20 MB.
  2. Set the blur radius to the strength you want.
  3. Apply the process to produce the blurred version.
  4. Compare it with the original, then download the file if the look works.
  5. If the blur is not enough, increase the radius and run the process again from the original file.

Example

A creator wants to publish a screenshot without revealing a visible folder name. They upload the image, increase the blur radius until the text becomes unreadable, then check that the other elements still look presentable. They also confirm that the blur covers the whole sensitive area.

Limits and formats

Where processing happens

The blur is executed locally in the browser. Your image is not uploaded and stays on the device throughout the operation.

Frequently asked questions

What radius should I choose to hide text?

It depends on the text size and image resolution. Start with a moderate value, increase it gradually and zoom in on the sensitive area to confirm that it can no longer be read.

Can I blur only a face?

No, this tool applies blur to the entire image. To target a face or a license plate, use a zone masking tool with coordinates instead.

Does blur preserve PNG transparency?

Processing acts on visible pixels. Transparent areas may be preserved or changed depending on the browser rendering. Check the final file if transparency matters for your project.
