Photo Blur Tool

When a screenshot contains an account number, an email address, or a face you don't have permission to share, you need to obscure it before it goes anywhere. This tool lets you blur image online with a Gaussian blur applied across the whole frame, at a radius you control from 1 to 50 pixels. The live preview updates as you drag the slider, so you can watch the content become unreadable in real time. It handles one photo or hundreds through an automatic bulk mode, and everything runs on a canvas in your browser, so the pictures stay on your machine. No watermark, no account, no upload queue.

Bulk supported. Drop multiple files and they'll be processed in a queue with a single ZIP download. Same settings apply to every file.

How to use

01

Add your images

Drop a single photo for a live preview, or drag in a whole folder's worth and the tool flips into bulk mode automatically. Any browser-supported image format works.

02

Set the Radius slider

Drag between 1 and 50 pixels. Around 4 gives a soft haze, 12 obscures faces at normal viewing size, and 30 or more turns text into smears of colour.

03

Click Blur and download

Single files download with -blurred added to the name and keep their original format. Batches get processed one by one and packaged into blurred-images.zip.

Why Photo Blur Tool

Common questions

Is there a way to blur only one area of a photo?
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.
Is blurring text safe enough to hide sensitive information?
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.
What blur radius should I use to hide a face?
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.
Does the blur tool upload my photos anywhere?
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.
How do I blur background online while keeping the subject sharp?
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.
What happens when I blur hundreds of photos in one go?
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.
Why use this instead of Photoshop to blur a photo?
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.
