Blur & pixelate image
Blur the whole image, or censor a face or detail by pixelating an area — locally, no upload.
Blur and pixelate images in your browser
Blurring an image softens detail across the whole picture or hides something sensitive in one spot — a face, a name badge, a licence plate or a detail in a screenshot. This tool does both: a smooth blur or a chunky pixelate, applied to the entire image or just to an area you select.
Everything happens on the canvas in your browser, so the original photo is never uploaded — exactly what you want when you are censoring private information. Pick blur or pixelate, drag the strength, and either cover the whole image or draw a box over the part to hide.
Pixelate (mosaic) is the safest way to censor faces and text because it removes the underlying detail entirely; a light blur can sometimes be reversed, so use a strong setting for anything you truly need to hide. Export as PNG to stay lossless or JPG for a smaller file.
Privacy by design
All processing happens inside your browser. Your files never reach a server — there is nothing to store, transmit or share.

Load not just one image but as many as you like — by drag & drop or multiple-select. imagenimble processes them one after another, locally in your browser, and packages the results as a single ZIP download. No upload, no account and no fixed limit — only your device’s memory caps very large batches. It is the quick way to convert or edit a whole folder in one go.
