Soften a region so attention stays on the main subject.
Upload an image and open the blur workspace.
Choose the blur area and intensity for the selected region.
Apply the blur and download the altered image.
I built this when a background element needs softer attention but the main subject stays visible.
This is a lighter privacy layer than a hard pixelation pass.
You can keep the better parts of a photo readable while the background becomes less sharp.
The flow gives you control over a local region instead of forcing a whole-image treatment.

Formats, processing, and practical limits for this tool.
A local blur can make certain image details less visible, but it can't guarantee that a screenshot or photo is fully unreadable if the surrounding visual language is still strong.
Straight answers about this tool — privacy, formats, limits, and how processing works.
The whole image. Convert applies a full-frame Gaussian blur on the server — there is no region/mask selector. Use Pixelate if you need to obscure only a rectangle.
blur_strength must be between 0.1 and 50 (default 5). The slider matches that range in 0.1 steps; higher values produce a stronger soft focus.
No. The on-screen preview updates in your browser. Convert is the step that sends the file and blur_strength to the server for the downloadable result.
A new image named with a _blur suffix. ImageToolkit keeps your input format when possible; otherwise it saves as PNG.
