Image Blur

Blur an image or photo online in your browser with adjustable strength.

ToolsSoup's Image Blur is a free online tool that blurs photos and pictures right in your browser. Soften a busy background, hide a face, license plate, or sensitive text, or create a frosted-glass effect, then download the result in seconds — with no uploads, no watermarks, and no sign-up. Your images never leave your device.

What is an image blur tool?

An image blur tool smooths out the detail in a picture by averaging each pixel with its neighbours, producing a soft, out-of-focus look. The higher the blur strength, the more the fine detail disappears. People use blurring to anonymise faces and personal information, to draw attention to a sharp subject by softening the background, or simply for a stylistic frosted effect. This tool redraws your image onto a fresh canvas with a Gaussian blur applied and lets you download it as a new file at the same resolution.

How to blur an image online

Blurring an image with ToolsSoup takes just a few seconds:

  1. Click Choose an image and select the photo you want to blur.
  2. Drag the blur strength slider to set how soft you want the result, in pixels.
  3. Watch the live preview update so you can dial in the exact amount of blur.
  4. Choose an output format (PNG, JPEG, or WebP), click Blur image, and download the result.

Blur faces, text, and backgrounds

A light blur is great for softening a distracting background so the main subject stands out, while a strong blur fully obscures detail — ideal for hiding a face, a name, an address, a license plate, or any sensitive information before sharing a screenshot or photo. Because the blur is applied to the whole image, crop to the region you want to obscure first if you only need part of the picture hidden.

Frequently asked questions

Is this image blur tool free?

Yes. Every tool on ToolsSoup is completely free to use, with no account, sign-up, watermarks, or hidden limits.

Are my images uploaded to a server?

No. All blurring happens locally in your browser using the HTML canvas, so your images are never uploaded, stored, or seen by anyone but you.

Can I blur a face or sensitive text in a photo?

Yes. Increase the blur strength until the detail is no longer readable to anonymise a face, name, address, or license plate. The blur applies to the whole image, so crop to the area you want hidden first if you only need part of it obscured.

Can a blurred image be unblurred?

Once you download a strongly blurred image, the original detail is effectively gone — a heavy blur permanently discards information and cannot be reliably reversed, which is why it is useful for hiding sensitive content.

What image formats are supported?

You can load common formats such as JPG, PNG, and WebP, and export the blurred result as PNG, JPEG, or WebP.
