Square, rounded, circle, or diamond tiles, sized and spaced to taste. Pick the grout color to suit. Subway tile, pixel art, mosaic-art reference, sticker-sheet patterns. Nothing uploads. For real mosaic art, get tiles and grout.

Mixing the grout…
where mosaic earns its keep
for design
Considering a new tile pattern for a bathroom? Run a photo of the room — or even an inspiration photo from another bathroom — through square tile mode at small size with white grout. The mosaic shows what subway-tiled walls would look like at the actual scale of the space.
for posters
Big tiles + black grout color = pixel-art aesthetic for a flyer or poster. Drop a portrait through with 30px tiles, black gaps, square shape. Looks like 8-bit chiptune-era graphic without a sprite editor.
for tile work
Real mosaic artists use pixelated reference images to work out tile placement. Generate a mosaic preview at the tile count you'll use (count rows/columns of your physical tiles), print, work tile-by-tile from the printout. Saves a lot of squinting at a blurry source.
for ig
IG carousel posts that look like 'a single image at first, then turns out to be a tile pattern' get saves. Pair the mosaic effect with a 1:1 crop and your account picks up a pattern-content niche.
for prints
A 24×36 print of a mosaic'd photo reads as the original image from across a room and as colored tiles up close. Same trick fancy bathrooms use, applied to a printable. Frame it.
for stickers
Run a photo through with 10px circle tiles + 4px gap. The result reads as a dot-pattern sticker sheet. Great for journal washi-strips or scrapbook accents — print, hand-cut into strips, glue.
in case you're wondering
No. The tile sampling and rendering both run in your browser. Your photo never touches our servers — we don't run an image pipeline at all.
Pixelate fills every pixel of each cell with a flat color edge-to-edge. Mosaic leaves gaps between cells, fillable with a 'grout' color. The gap is what reads as 'tile' instead of 'low-resolution'. Adjust gap to 0 and it's effectively pixelate.
Circle tiles leave triangular gaps between them — those gaps fill with the gap color, which dominates if you set a light grout. For circles, pair with a dark grout color so the photo reads through; for squares any grout color works.
10-20px reads as 'subway tile' or 'mosaic art'. 25-40px reads as 'pixel art' or 'chunky pattern'. Below 8px and you lose the tile feel; above 60px the photo becomes unrecognizable. Match the source resolution — a 4000px photo can take 30px tiles; a 800px photo wants 8-12px.
If the photo's dimensions don't divide evenly by the tile size, the right and bottom edges get partial tiles. The gap-color background fills those partial spots, but you may see asymmetric trim. Adjust tile size for cleaner edges if it bothers you.
Not directly here — but the result feeds well into the Color Palette tool. Run the mosaic JPG through the palette extractor at high palette count to get the dominant tile colors as hex codes.

Real ceramic mosaics use 1cm tesserae set in lime-mortar grout. Roughly $80 in materials for a 30×30cm panel. Slow, satisfying, archival. The digital version is the rehearsal.
