Sometimes you only want to blur one part of a photo — a face, a number plate, an address, or a private detail — while leaving the rest sharp. This tool lets you drag a box over the exact area and blur just that region.

What you can do with Blur Part of an Image
Blur Part of an Image is built to do one job well, and gives you everything you need to get it exactly right:
Targeted blur. Blur only the region you select, not the whole image.
Hide sensitive info. Cover faces, plates, addresses, or other private details.
Private by design. Processed in your browser, so the original never leaves your device.
Free, no watermark. Unlimited use.
Hide a detail, keep the rest
Blurring an entire photo defeats the point when you only need to hide one thing. Selecting a single region here keeps the image useful while protecting the part that matters.
Whether you need it once or every day, Blur Part of an Image keeps the process quick and predictable. Because it focuses on a single task, there are no crowded menus to wade through — you open the page, set what you need, and get your result. That simplicity is exactly why a dedicated image tool beats a heavyweight editor for a job like this.
Everything runs in your browser
Unlike most online tools, Blur Part of an Image never uploads your image to a server. The moment you choose a file, it is processed right here in your web browser using your own device's power. Nothing is sent over the internet, nothing is stored, and nothing is shared with anyone.
That gives you two real advantages. First, it is private: sensitive documents, ID photos and personal files never leave your computer or phone. Second, it is fast — there is no slow upload or download round-trip, so even large files are handled almost instantly. And it is completely free, with no watermark added to your result and no account required.

- Targeted blur: Blur only the region you select, not the whole image.
