π«οΈ Blur Image
Blur a whole photo or drag a box over faces, plates, and text. Adjustable strength.
Blur Photos for Privacy or Style
Blurring is the quickest way to hide sensitive details in a photo: faces of bystanders, license plates, house numbers, computer screens, and documents caught in the background. This tool gives you two modes. Region mode lets you drag a rectangle over exactly what to hide, leaving the rest of the photo untouched. Whole-image mode softens the entire picture, which photographers use for dreamy effects and designers use for backgrounds. The strength slider controls how heavy the blur is, from a subtle softening to a fully unreadable smear, and the preview updates live.
For privacy work, the details matter. Draw the region generously: a tight box around a face can leave the chin or forehead recognizable, and a half-blurred license plate is still readable. Crank the strength until you genuinely cannot make out the detail at full zoom, then check once more before you share. The blur is baked into the pixels of your download, so unlike a sticker or emoji overlay added by some apps, there is no hidden layer to peel back. And because the whole thing runs in your browser, the sensitive photo never travels over the network, which is exactly the privacy story you want from a privacy tool.
Creative Uses for Blur
Beyond redaction, blur is a legitimate photographic effect. A light whole-image blur (2 to 6 px) softens skin in portraits without the plastic look of heavy retouching. A strong blur turns any photo into an abstract gradient background for websites, slides, and video calls, recognizable enough to feel intentional but busy enough to hide nothing important. Designers blur a copy of a photo, darken it, and put white text on top for hero sections. You can also fake depth of field: blur the background region of a photo while keeping the subject sharp to mimic a wide-aperture lens.
Blur vs. Other Redaction Methods
Solid black boxes are the most absolute redaction, but they scream censorship and wreck the composition. Pixelation (mosaic) is the classic TV look, though light mosaics have occasionally been partially reversed by researchers, so use chunky blocks if you go that route. Gaussian blur, what this tool does, is the newsroom standard: it looks natural, it degrades detail smoothly, and at high strength it is effectively irreversible. Whatever method you choose, apply it to a copy and keep the original somewhere safe, because redaction should always be one-way.
Tips for Clean Results
Work at full resolution: blurring a small preview and upscaling later looks muddy. If you need several regions, blur them one at a time by dragging a new box each time; the tool applies each region permanently to the working image. For video-call-style background softness on a still, use whole-image mode at low strength. Download as PNG when the image has text or sharp graphics (JPG artifacts plus blur looks messy), and as JPG for large photos where file size matters.
Frequently Asked Questions
How do I blur part of a photo, like a face or license plate?
Upload the image, switch to Region mode, then click and drag a rectangle over the area you want to hide. Move the strength slider until the detail is unreadable, then download. The blur is baked into the downloaded pixels, so it cannot be reversed. For faces, draw the box a little larger than the face itself, since partial blurs can sometimes still be recognizable.
Can I blur the whole image?
Yes. Choose Whole image mode and set the blur strength. Photographers use a light whole-image blur to create dreamy backgrounds or to soften skin in portraits. A heavy blur turns any photo into an abstract color wash, which works nicely as a website hero background or a placeholder while content loads.
Is a blurred face truly unrecognizable?
A strong Gaussian blur over a generous region is effectively irreversible for casual viewers, which is why news outlets use it. But be thorough: blur the entire head, not just the eyes, and check the result at full size before publishing. Also remember that context, clothing, and tattoos can still identify someone even with the face blurred. For maximum privacy, combine blur with cropping.
What is the difference between blur and pixelation?
Gaussian blur smooths pixels into soft gradients, which looks natural and is the standard for privacy. Pixelation groups pixels into chunky blocks, the classic mosaic censorship look. This tool uses Gaussian blur, which generally looks cleaner and is harder to partially reverse than a light mosaic. If you specifically want the pixelated look, a very high blur strength on a small region approximates it.
Will blurring reduce my image quality?
Only in the blurred areas, which is the point. Unblurred regions keep their original pixels untouched. The download re-encodes the image though, so choose PNG for zero additional loss or high-quality JPG for photos. The tool never upscales or downscales your image unless you ask it to.
Do you keep my photos?
No. Blurring runs entirely in your browser with the Canvas API. Your image is never uploaded, stored, or seen by anyone but you, which is exactly what you want when the photo contains faces, plates, or documents you are trying to hide.
