Our free online random bitmap generator creates unique pixel art patterns with complete control over dimensions, colors, and density. Perfect for generating pixel art inspiration, creating retro game assets, designing backgrounds and textures, or exploring procedural art. Each generation is completely random, ensuring unique results every time. Generate bitmaps from tiny 8x8 sprites to large 512x512 textures with customizable color schemes and pixel density.

Monochrome uses a single color for filled pixels and a background color for empty pixels. Perfect for creating classic black and white pixel art or using your brand colors. The density slider controls what percentage of pixels use the primary color versus the background.

Grayscale generates random gray tones for each filled pixel, creating textured patterns with depth. Each pixel gets a random brightness value from black to white, producing organic-looking noise patterns ideal for textures and abstract art.

Full Color assigns completely random RGB values to each filled pixel, creating vibrant, chaotic patterns. This mode produces the most variety and is excellent for colorful abstract art, glitch aesthetics, or when you want maximum randomness and visual interest.

Custom Two-Color lets you define two specific colors that will be randomly distributed throughout the bitmap. Each filled pixel randomly chooses between your primary and secondary colors, creating patterns similar to dithering. Great for duotone effects, complementary color schemes, or brand-specific patterns.
