Blur Part of Image Online

Blurring part of an image lets you soften or hide a specific region while the rest of the photo stays perfectly sharp. It is the go-to move when one area of a picture distracts the viewer, reveals private information, or simply does not belong in the frame. Instead of editing the whole photo or starting over in desktop software, you can target just the spot that needs work and leave everything else untouched. A selective blur keeps the context of your image intact, so a screenshot with one redacted line still reads naturally and a photo with one softened corner still looks like the same moment. This precision is why selective blur has become one of the most useful everyday edits for sharing images online.

This tool applies a selective blur with a brush rather than automatic detection, which means you decide exactly what gets blurred and what stays clear. After uploading, switch to Selective mode and paint over the part of the image you want softened; the area under your stroke turns smooth while the surrounding photo remains crisp. Adjust the brush size and softness to follow straight edges or irregular shapes, and use the Keep brush to protect a detail you want left sharp. Because the blur is rendered on a canvas inside your browser, the preview updates live as you paint and nothing is uploaded to any server. Manual control also avoids the cut-out mistakes that auto-masking sometimes leaves around complex edges and fine detail.

Selective blur is handy in far more situations than people expect. Redact an email address, order number, or password in a screenshot before sending it to support. Soften a cluttered background corner in a product shot while the item stays sharp. Hide a license plate, house number, or stranger’s face in a street photo before posting it publicly. Blur a reflection in a window, a name tag at an event, or a line of text on a document without flattening the whole image. Group photos are easy: paint each area you want hidden in turn, and switch to Keep to leave one person or object visible on purpose. However subtle or strong the effect, the same brush gives you the exact region you need.

Everything runs locally on your device. Your image is read into a canvas, the part you choose is blurred, and the result is exported back to you without ever leaving your computer, so private pictures never reach a server. You can save the edited image as PNG, JPEG, or WebP to match your project, and cap the maximum width to keep the file small for the web. There is no account, no watermark, and no queue — open the tool, blur the part you want, and download in seconds. It works on screenshots, portraits, product photos, and documents alike, on desktop or mobile. The whole workflow is reversible until you download, so you can experiment freely and re-blur if you missed a spot.
