Image Mosaic - Free Online | ToolXHub

After uploading the picture, you can use the mouse box to select the area that needs to be mosaically, or you can select the full picture application. The size of the mosaic block can be adjusted, and the larger the block, the higher the degree of blurring. Square and round mosaic shapes are supported, and circles will produce a softer transition effect.

The implementation principle is to divide the selection into fixed-size blocks, calculate the average color of all pixels in each block, and then fill the entire block with this average color. All of this is done locally in the browser through Canvas pixel operations and no pictures are uploaded.

The most commonly used scenes are to block sensitive information in photos, such as license plate numbers, mobile phone numbers, faces, etc., and are also used to create pixel-art style effects pictures.

The online image mosaic tool adds a mosaic blur effect to specified areas of the image or the entire image, and supports adjusting the size and shape of the mosaic blocks.
