Need to blur the background, not the subject?
Our AI separates the subject from the background and blurs only the backdrop, like portrait mode. Remove or replace the background in the Azurade AI studio.
Blur a photo online without sending it anywhere
If the reason you are blurring a picture is that it contains something private, uploading it to a stranger's server to get that done is an odd trade. Here the blur happens inside your browser tab: the file is decoded on your own machine, the blur is drawn onto a canvas there and the download is built from that canvas, so the photo is never transmitted or stored. PNG, JPG, WebP and the HEIC photos an iPhone saves all open, and the result comes out as PNG or JPG at the original pixel dimensions.
Blurring one part of an image
Switch to Region and drag a box over the thing you want gone. The rest of the picture stays sharp and the box can be moved after you draw it, so covering a face or a house number takes a couple of seconds. People reach for this mode when a photo they're posting happens to include a license plate, a child, a colleague who did not agree to be in it, a delivery label with an address, or a screenshot with an email in the corner.
How strong is strong enough
The slider sets the blur radius in pixels, up to 60, and the effect scales with the size of your image. That last part is what people get wrong when redacting: a radius of 10 pixels hides a face in an 800 pixel photo and leaves it readable in a 4000 pixel one, because the same radius covers a far smaller share of the frame. Judge by the preview and not by the number, and when the point is concealment go further than looks necessary. Be most suspicious of lettering. Text survives blurring better than faces do, and a license plate can stay legible at settings that turn a face to mush.
Soft background, and what this tool cannot do
Whole photo mode blurs everything evenly, which suits a soft backdrop behind text, a frosted header image or a blurred thumbnail. What it cannot do is keep the person sharp while blurring what is behind them, because that needs a model that knows which pixels are the subject. The Azurade AI studio has that: its background removal and background replacement modes separate the subject first, which is also how you get a portrait-mode look out of a photo that was shot without one. For the simpler neighboring jobs, Crop Photo cuts the offending corner out entirely, and Image Compressor shrinks the file once you are done.
Frequently asked questions
Can the blur be reversed by someone who gets the file?+
The exported file contains only blurred pixels, so the original detail is not hidden inside it waiting to be switched back on. A weak blur can still be partly undone by sharpening, though, so for anything you are hiding on purpose push the strength well up and check the preview at full size before you save.
Can I blur more than one area in the same photo?+
One box at a time. To cover two faces, blur the first area, download, load the result back in and blur the second. Or use Whole photo if everything in the frame is sensitive.
Does it blur only the background and keep the person sharp?+
No. This tool blurs either the entire picture or the rectangle you draw, with no understanding of what is in it. Separating a subject from its backdrop the way portrait mode does needs a model, and that lives in the AI studio rather than here.
What shape is the blurred region?+
A rectangle you drag with the mouse, which you can then move around. There is no freehand brush or circular mask, so plan the box to cover the whole of what you want gone rather than trimming it tight.
Does the photo lose resolution?+
No. The blur is applied at the original pixel dimensions and the file downloads at full size. PNG keeps everything else untouched, while JPG re-encodes at quality 92.
Is the photo uploaded to a server?+
No. Blurring runs on a canvas inside your browser tab and the download is created there.
