Photo Blur Tool

This tool applies the Gaussian blur to the entire frame. To blur part of image content only, crop the sensitive region out with the Image Cropper, blur that piece here, and paste it back in any editor. For faces and plates, the Pixelate Image tool is often the faster route.

Often not. Researchers have recovered blurred text and numbers by simulating the blur against candidate strings until one matches the smear, which works especially well when the font and layout are known, like a bank statement. For anything truly sensitive, push the radius high or cover the region with a solid block instead.

At typical photo sizes, 12 pixels makes a face unrecognizable at a glance, but enlargement can still reveal structure. For real anonymization go toward 30 to 50, and remember the radius is measured in source pixels, so a 4000 pixel wide photo needs a larger radius than a 1200 pixel one.

No. The blur is drawn on an HTML canvas inside your browser and the result is saved straight from there. That matters for exactly the kind of images people blur: IDs, statements, and screenshots with tokens or home addresses in them.

Pair this with the Background Remover: cut the subject out there, blur the original photo here, then layer the sharp cutout over the blurred copy in any editor. That gives you a portrait-style depth effect with full control over how strong the blur is.

Bulk mode kicks in as soon as you add more than one file. Every image gets the same radius applied and the results come back as blurred-images.zip. Processing is sequential and local, so big batches just take a little patience.

Speed, mostly. There's no install and no learning curve: people looking to blur photo free of cost get a slider, a preview, and a download button in one screen. A full editor wins when you need masked, region-specific blurs or layered compositing.

Yes. You blur photo online free with no signup and no watermark, just a radius slider and a download button. To make photo blur online you drop an image, drag the radius, and save, and the whole thing runs in the browser.

This one does. As a picture blur tool it renders a live preview that updates as you drag the radius, so you blur picture online and see exactly how strong the effect is before downloading. No guessing, no re-doing.

Focus. This image blur tool does one thing, a Gaussian blur across the whole frame, so there's no menu to hunt through. As a free photo blur tool it skips accounts and watermarks, and being a lightweight photo blur tool it loads fast and works on phones.

Yes. The online photo blur tool applies the blur on a canvas inside your browser, so nothing is sent to a server. You blur image online free while the photo, whether it's an ID or a screenshot, stays on your device the entire time.

It's a focused image blur maker, not a layered blur image editor. The single blur tool it gives you is a radius from 1 to 50 pixels applied to the whole image. For selective, region-by-region blurring you'd want a full editor, but for fast whole-frame blur this is quicker.

Not directly, since this blurs the whole frame. For photo background blur online free with the subject kept sharp, pair it with the Background Remover: cut the subject out there, blur the photo here, and layer them. A true blur background photo editor online with auto-masking is a heavier tool than this.

One-click background-only blur needs subject detection, which this tool doesn't do. To blur image background online free, remove the subject with the Background Remover, blur the leftover background here, then recombine. It's two steps, but every part stays free and in your browser.

Yes. It applies a real Gaussian blur, the same smooth, bell-curve spread editors use, rendered through the browser's canvas filter. A gaussian blur image online like this looks natural because nearby pixels blend gradually rather than in hard steps.

Yes. Drop more than one file and bulk mode starts automatically, applying the same radius to each and returning a ZIP. The bulk image blur browser workflow is sequential and local, so a big batch just takes a little patience, and none of it uploads.

Each result downloads straight from the browser. In single mode the blur image download keeps the original format and adds -blurred to the name; in bulk mode everything arrives as blurred-images.zip. There's no wait screen because the file is generated right on your machine.

No, this tool adds blur, it doesn't reverse it. You can't reliably make blur photo clear online, because heavy blur discards detail that no tool can invent back. A slightly soft photo might improve with the AI Image Upscaler, but a genuinely blurred image stays blurred.

Partly reversible, which is the catch. A Gaussian blur is a math operation with a known shape, so software can sometimes deconvolve it and pull back a rough version, especially at a low radius. Pixelation instead averages each block down to one color, discarding that detail outright, though it too can be guessed at for faces and text. Neither is guaranteed safe, so for real redaction push the radius high or cover the area with a solid block, and weigh the Pixelate Image tool as the other option.
