Frequently Asked Questions
How do I securely blur faces or license plates in a photo?
Upload your photo to our Blur Image tool, select the specific area you want to obscure using the brush or box tool, and apply the blur. Download the safe image instantly.
Is it safe to blur highly sensitive documents online?
Yes, it is 100% safe. Our tool uses HTML5 Canvas to process the image locally in your browser. Your unblurred original photo is never uploaded to the internet.
Can I blur the entire background of an image?
Yes, you can adjust the brush size to cover large areas, allowing you to manually blur out the entire background to focus on the subject.
What is the difference between Gaussian Blur and Pixelation?
Gaussian Blur creates a smooth, out-of-focus smudge effect, while Pixelation turns the area into large, blocky squares. Both effectively hide sensitive data.
Can the blur be reversed or removed later?
No. Once you apply the blur and download the new JPG/PNG file, the original pixels are permanently destroyed in that copy. It cannot be 'unblurred' by forensics.
Does blurring a part of the image reduce the file size?
It can actually decrease the file size slightly, as blurred areas contain less intricate detail and color variation, which compresses more easily in JPG format.
Can I use this tool on my iPhone or Android device?
Yes, the tool is fully touch-responsive, allowing you to use your finger to paint blurs over faces or text directly on your mobile browser.
Is there a limit to how many photos I can blur?
No, the tool is completely free with no usage limits and no account registration required.
