Can I pixelate multiple images at once?

Yes — batch processing is fully supported with no file count limit. All images are processed locally in your browser. You can upload an entire folder of photos and apply the same pixelation settings to all of them, then download as a ZIP archive.

What are the Game Boy, NES, and C64 palettes?

These are the original color palettes from classic gaming hardware. The Game Boy palette has 4 shades of olive green. The NES palette contains 54 colors used by Nintendo's 8-bit console. The Commodore 64 palette has 16 distinctive 1980s computer colors. Applying these palettes to your photos recreates the authentic look of those retro platforms.

What is Floyd-Steinberg dithering?

Floyd-Steinberg is an error-diffusion dithering algorithm that creates natural-looking color transitions by spreading quantization error to neighboring pixels. It's the standard algorithm for creating authentic retro pixel art — the characteristic grainy texture of classic games comes from this technique.

Will pixelating make my image blurry?

No — pixelation creates a blocky, low-resolution look, not a blurry one. Each pixel block is a solid color, giving the image a crisp, retro appearance. The smaller the pixel size, the more detail is preserved; larger pixel sizes create a more abstract, blocky effect.

Can I add my own custom color palette?

Yes. In Pixel Art mode, you can manually enter HEX color codes to build your own custom palette with 2–32 colors. This is useful for matching a brand color scheme, creating a consistent look across a series of images, or designing your own retro game aesthetic.

Does pixelation work for censoring sensitive information?

Absolutely. Quick Pixelation mode with a pixel size of 8–16px effectively obscures faces, license plates, text, and other sensitive content while still looking intentional and clean. Unlike blurring, pixelation is irreversible — someone cannot "sharpen" a pixelated image to recover the original.

Guides & Tips

Quick Pixelation vs Pixel Art Mode — What's the Difference?

Quick Pixelation is designed for speed and simplicity. One slider controls the pixel block size — drag it to the right for larger blocks (more abstract), drag left for smaller blocks (more detail visible). Use this mode when you need to censor sensitive information (faces, license plates, text in screenshots) or when you want a quick creative pixel effect without tweaking settings. The result is a straightforward blocky version of your image.

Pixel Art Mode unlocks the full retro art toolkit. Beyond pixel block size, you get:

Palette selection — Apply classic game console color palettes (Game Boy's iconic 4-shade green, NES's 54 colors, Commodore 64's 16 colors, PICO-8's 16 modern-retro colors) or define your own custom palette with specific HEX colors.
Dithering algorithms — Floyd-Steinberg dithering creates natural, noise-like color transitions (the classic retro game look). Ordered dithering (Bayer matrix) produces a distinctive mechanical grid pattern. No dithering gives the hardest, most blocky result.
Grayscale mode — Convert to black-and-white first, then pixelate. Pair with the 2-color or 8-color grayscale palette for an authentic newspaper-print or vintage photo feel.

Use Pixel Art mode when you're creating game assets, retro-style artwork, or profile pictures with a distinctive 8-bit/16-bit aesthetic.

What is Dithering in Pixel Art? Floyd-Steinberg vs Ordered Dithering

Dithering is a technique that uses patterns of dots in available colors to simulate colors that aren't in the palette. In pixel art, dithering creates the illusion of more colors and smoother gradients than the limited palette actually contains — it's what gives retro game art its characteristic textured look.

Floyd-Steinberg dithering (default): The most widely used error-diffusion algorithm. It works pixel by pixel, spreading the "error" (difference between the original color and the closest palette color) to neighboring pixels. The result is organic, noise-like transitions that look very natural. This is the algorithm behind most classic pixel art tools. Best for: portraits, landscapes, and anything where you want smooth, natural-looking color transitions.

Ordered dithering (Bayer): Uses a fixed threshold matrix (Bayer pattern) to decide whether each pixel becomes one palette color or another. The result is a distinctive crosshatch or grid-like texture that feels more mechanical and structured. Best for: technical illustrations, UI mockups with a retro-computing vibe, or when you want the dithering pattern itself to be a visible design element.

No dithering: Each pixel is directly mapped to the closest palette color with no blending. The result is the hardest, most blocky look — large flat areas of solid color with sharp transitions. Best for: bold graphic designs, icon-style pixel art, or when you want maximum contrast between color regions.
