This mosaic effect tool converts any image into a tiled arrangement of colored cells, sampling the underlying photo to generate the pattern. ## Tile geometry and spacing
The cell structure defines the core look of the mosaic filter. You can choose between uniform square tiles or an organic rock pattern for a more natural, stained-glass appearance. The tile size determines the resolution of the pattern, while grout thickness controls the spacing between each cell.
Irregularity and texture
Real mosaics are rarely perfect. The hand-laid irregularity control introduces variation to the tile placement and shape, breaking up the rigid grid for a more authentic, handmade feel. This prevents the mosaic effect from looking like a simple digital pixelation filter.
Lighting and grout styling
To give the tiles physical depth, the bevel slider adds highlights and shadows around the edges of each cell. You can also customize the grout color, allowing this mosaic effect online to mimic everything from bright swimming pool tiles to dark cobblestone joints.
