Koadro
Koadro turns your photos into real pixel art, made of actual pixels you control, not an AI's guess at your face. Import a photo, then set the pixel size, color count, palette, and dithering, and watch the result update live. Choose designed palettes like Noir, Matcha, Sepia, Dusk, and Riso, or true retro sets like CGA and PICO-8. Export a crisp avatar or a transparent-background sticker that drops straight onto any profile, story, or chat.
Everything runs on-device and works offline. No AI, no ads, no subscription, and no watermark. Koadro is free to use; a single one-time Premium unlock raises the resolution and color ceilings (up to 256 cells and 64 colors), adds diamond and hexagon mosaics, physical-size mode, 2048px export, custom palettes, presets, and unlimited projects. Available for iPhone, iPad, and Android.

Aseprite
Aseprite lets you create 2D animations for video games. From sprites, to pixel-art, retro style graphics, and whatever you like about the 8-bit and 16-bit era. It has a color mode, which tell you how many colors the image can handle. All images in the sprite are in one specific mode, you cannot mix RGB images with Indexed images in the same sprite. It contains a set of layers. You can see them in the Timeline. The most important concept here is that there are two kind of layers: the background layer for opaque sprites, and transparent layers. A sprite can contain only one background layer, but several transparent layers. It contains animation frames. Each frame has a duration, i.e. how many milliseconds the frame must be on screen when the animation is being played. Integrate Aseprite in your assets pipeline with the command-line interface (CLI). Store several animations in one texture atlas.
