What is image mosaic and blur?
Image mosaic and blur is an online tool that applies a mosaic or blur to selected areas of photos and images. It's useful for hiding faces and personal information before posting on social media, or masking private data in blog screenshots.
SOKUFU's image mosaic and blur runs entirely in your browser, so your images are never uploaded to a server. A tool meant to protect privacy shouldn't put it at risk.
Adjust the strength and the areas while you watch, and cover several spots in one image. It works for hiding nameplates in real estate photos, cleaning up backgrounds for e-commerce, or masking personal details in report attachments. No sign-up, no login, and it's free.

Photos face detection struggles with (side views, small faces, masks)
This tool uses a small AI model (about 230 KB) that runs on your own device. Faces looking toward the camera are found reliably, but faces in full profile, small faces far away, faces largely covered by masks or sunglasses, and faces in dark photos can be missed. Always check that every face is covered before you share the image.
