About Blur Image

Screenshots and photos leak information: faces of bystanders, license plates, email addresses, account numbers in a corner of the frame. Blurring the sensitive region lets you share the image while protecting what shouldn't be public.

Apply blur to selected regions or the whole image, with adjustable strength. For genuinely sensitive data, blur hard — modern tools can sometimes reconstruct lightly blurred text, so when in doubt, increase the strength until nothing is guessable.

How to use Blur Image

1
Load the image
Open the screenshot or photo containing sensitive content.
2
Select the region
Drag over faces, plates, or text you need to hide — or blur the entire image.
3
Set the strength
Increase until the content is truly unreadable, not just fuzzy.
4
Export
Download the redacted copy safe for sharing; your original stays untouched.

Tips for better results

✓Lightly blurred text can sometimes be reconstructed — use maximum strength on account numbers and IDs.
✓Blur before uploading anywhere, not after; copies of the sharp original may persist.
✓Check reflections and backgrounds — screens, mirrors, and windows often leak the thing you meant to hide.

Frequently Asked Questions

What is the difference between Gaussian and Pixelate blur? +

Gaussian blur creates a smooth, soft blur effect — good for background blurring. Pixelate creates a blocky mosaic effect, which is better for hiding faces, license plates, text, or any private information.

Can I blur just part of an image? +

Yes. Switch to Area Blur mode, then click and drag on the image to draw rectangles over the areas you want to blur.

Will the original image quality be preserved outside blur areas? +

Yes. Only the selected areas are blurred. The rest of the image remains at full original quality.

What image formats are supported? +

JPG, PNG, WebP, and BMP are all supported. The output is always saved as a PNG.

Are my images sent to a server? +

No. All blurring happens entirely in your browser using the HTML5 Canvas API.
