Mosaic and blur images online, privately
Before sharing a photo you often need to hide a face, a license plate, a house number, an ID number or personal info in a chat screenshot. This mosaic tool lets you drag right on the image to select an area and apply a mosaic (pixelation), gaussian blur or a solid color box to cover sensitive content in seconds.
100% local processing, no uploads
Unlike many online mosaic services that upload your images to a server, this tool runs entirely in your browser using the Canvas API. Your images are never uploaded, stored or sent to any third party — ideal for IDs, contracts and any photo containing personal information.
Mosaic, blur or solid box?
Mosaic pixelates the region into blocks, balancing privacy and looks. Gaussian blur softens the area and is great to blur a face online or a busy background. A solid box fully covers the area — the safest, non-reversible option for ID numbers and anything that must never leak. Adjust the mosaic block size and blur strength to taste.
