About Image Mosaic Maker

The Image Mosaic Maker is a browser-based tool for applying pixelation (mosaic) effects to your images. Adjust the block size freely (2–128 px), or use preset buttons—Subtle, Medium, and Strong—for instant configuration.

It offers two modes: full-image mosaic and selection-based mosaic where you drag to define the target area. Hide faces before posting on social media, mask confidential information in screenshots, or blur license plates in photos with ease.

All image data is processed entirely in your browser, so your personal information never reaches any server. Get real-time preview updates and export to PNG, JPG, or WebP format—a secure and intuitive privacy tool."
