Turn a photo or AI-generated image into pixel art (dot art) and save it as a PNG — entirely in your browser. Get that chunky, low-colour, retro-game sprite look without opening a heavy image editor. It works by shrinking the image down to a coarse dot resolution, snapping each dot to a reduced palette, and then scaling it back up with nearest-neighbour (no blur) so the dots stay crisp squares. There are two main controls. Dot size makes each pixel bigger and the grid coarser (a lower dot resolution) for a blockier result. Colours per channel lowers how many steps each of red, green and blue can use, giving a limited NES / Game Boy-style palette. You can also switch on grid lines, which draw thin lines along every dot boundary — handy as a pattern guide for fuse beads (Perler / Hama beads), pixel art or cross-stitch, where you need to count squares. The grid colour is adjustable. The preview is scaled to fit your screen, but the saved PNG is exported at the original pixel size, so it stays sharp when zoomed. Note: this tool shrinks and reduces an image. If you only want to enlarge existing pixel art without blurring it, use the separate pixel-upscale (nearest-neighbour enlarge) tool instead. Load images by dropping, clicking to choose, or pasting from the clipboard. All processing happens in your browser — the image is never sent to any server or API, so it's safe to use even where uploading files is not allowed.
