What this tool does

It applies one blur to the entire picture using the browser's built-in blur filter, which works like a Gaussian blur. The slider sets the radius in pixels, from 0 (no change) to 100. The default is 10.

It does not blur only part of an image. To keep a subject sharp and blur what is behind it, use Blur Background.

Uses

  • Background images behind text on slides, banners and websites, where a blurred photo keeps the colour and mood without competing with the text.
  • Placeholders shown while the real image loads.
  • Hiding content before sharing a screenshot or photo, such as a screen full of personal details.

Blur and privacy

A light blur on text or a face can sometimes be partially reversed or still read, especially for large, high-contrast text such as number plates. When hiding sensitive information, use a strong blur or, better, crop the sensitive area out with the Crop tool. Also remember that the original file, if shared alongside, still contains everything.

Output

Download as JPG, PNG or WebP at the original size. A blur draws in empty space from outside the frame, so the tool places the unblurred image underneath to keep the edges solid; at high values the outermost pixels can look a little sharper than the rest. Crop a few pixels off if that shows.

Where the processing happens

The blur is applied in your browser. The image is not uploaded and no model is downloaded.

Questions about this tool

I need to hide personal details in a screenshot. Is a blur enough?

Use a strong blur. A light blur on large, clear text can sometimes still be read. If the details are sensitive, cropping that part out with the Crop tool is the safest choice.

How do I make a soft background picture for a slide or banner?

Open the photo and raise the blur until the details are gone but the colours and mood remain. Then download it and put your text on top in your slide or design app.

Can I blur only part of the image?

No. This tool blurs the whole picture evenly. To keep a person or object sharp and blur what is behind it, use Blur Background.

Why do the very edges look slightly sharper at high blur values?

A blur pulls in empty space from outside the picture. To stop the edges fading out, the tool keeps the sharp image underneath, so the outermost pixels can look a little sharper. Crop a few pixels off if you notice it.
