What is dithering and when should I turn it on for pixel art?

Dithering scatters pixels of different palette colors to fake shades a limited palette cannot show, which stops flat regions from banding into harsh stripes. It matters most when you cut color down to just a handful of tones, such as a 2-color black-and-white look or a 4-color Game Boy palette. This pixelator offers three modes: Floyd-Steinberg error-diffusion gives the smoothest gradients and is best for photos; ordered Bayer-matrix dithering creates the regular cross-hatch texture seen on classic Game Boy and CGA screens; and a random mode adds grain. If you keep colors at full quality you usually do not need it at all. Pick a low palette size, switch dithering on, and compare all three modes side by side in the live preview to see which one suits your particular image best.

What block size should I use to get an 8-bit retro look?

Block size sets how many original pixels collapse into each solid color square, and this tool lets you choose anywhere from 2 to 64. Small values around 2 to 4 keep fine detail with only a subtle stair-step texture, which suits sprite cleanup or gentle stylizing. For a clear, chunky 8-bit console look, a block size of roughly 8 to 16 works well, while values above 30 produce a dramatic, heavily abstracted mosaic. The tool also displays the resulting block grid dimensions so you can see how low-resolution the output will read before exporting. The classic retro feel comes from combining a mid-range block size with a reduced palette. The fastest route is the 8-Bit Retro preset, then nudge the block-size slider until the detail level looks right for your image.

How do I pixelate just a face or license plate without blurring the whole photo?

Enable the selection tool, then drag a rectangle over the area you want to obscure, such as a face, license plate, or piece of on-screen text. The pixelation is applied only inside that box while the rest of the image stays sharp, so you can censor a sensitive region without ruining the surrounding photo. You can also invert the selection, which pixelates everything outside the rectangle instead and leaves the boxed area untouched, useful for spotlighting one subject against a blocked-out background. Because all processing runs locally in your browser, a private screenshot or personal photo never leaves your device while you anonymize it. Choose a larger block size for the selected region so individual features are fully unreadable, then export the result as PNG to keep the censored area crisp.

What is the difference between exporting pixel art as PNG and as SVG?

PNG, JPEG, and WebP are raster formats: they save the pixelated result as a fixed grid of dots, so if you scale the image up later the blocks themselves get resampled and can look soft or fuzzy. SVG is different because this tool writes each color block as a real vector rectangle, meaning the artwork stays perfectly crisp at any size with hard edges no matter how far you zoom. That makes SVG ideal for logos, print, or large displays where the chunky pixel look must stay sharp. PNG is the safe default for web use and preserves transparency, while JPEG and WebP add an adjustable quality setting for smaller lossy files. Pick PNG for general sharing or SVG when you need infinitely scalable pixel art, then download straight from the export panel.

Which retro hardware palette should I pick for an authentic console look?

Setting the palette to retro maps your image onto the actual colors a vintage system could display, giving a far more authentic result than a generic color reduction. Game Boy uses four green-tinted shades for that handheld monochrome feel; NES and SNES use their console color sets, with SNES allowing richer, more varied tones; and CGA and EGA reproduce the limited palettes of early PC graphics, CGA being especially small and stylized. Pairing a tight palette like Game Boy or CGA with ordered dithering recreates the exact cross-hatch shading those screens were known for. Each also has a one-click preset that bundles a matching block size and dither setting. Start with the preset closest to the era you want, then fine-tune the block size, and use the before/after slider to judge the match.

About the Image Pixelator

The Image Pixelator turns an ordinary photo or graphic into pixel art. Upload an image, choose how large each pixel block should be, and the tool resamples the picture into a grid of solid color blocks — the look of an old console game, a low-resolution avatar, or a mosaic. It is built for game artists prototyping sprites, designers making retro-styled graphics, streamers and creators who want an 8-bit aesthetic, and anyone who needs to blur or anonymize part of an image by reducing it to chunky blocks.

Everything happens in your browser. Your image is read, processed on an HTML canvas, and exported entirely on your own device — nothing is uploaded to a server, there is no account to create, and there is no watermark. That means you can pixelate a screenshot, a private photo, or unreleased artwork without it ever leaving your computer.

Pixel size, shapes, and palettes

Pixelation is controlled by a single block size, adjustable from 2 to 64 pixels. A small value keeps fine detail with a subtle stair-step texture; a large value produces a dramatic, blocky 8-bit effect. The tool also shows the resulting block grid dimensions so you know roughly how "low-res" the output will read.

Beyond plain squares, each block can be rendered as a circle, diamond, hexagon, or cross, which is how the tool produces halftone, mosaic, stained-glass, and cross-stitch styles from the same source image. Color can be left at full quality or reduced (quantized) to a limited palette of 2, 4, 8, 16, 32, 64, or 256 colors, converted to grayscale, or mapped to an authentic retro hardware palette — Game Boy, NES, SNES, CGA, or EGA. Reducing the palette is what gives pixel art its distinctive flat, banded look.

Dithering and built-in presets

When you cut colors down to just a handful, flat regions can band harshly. Dithering fixes this by scattering pixels of nearby palette colors to fake intermediate shades. The Image Pixelator offers Floyd-Steinberg (error-diffusion), ordered Bayer-matrix dithering, and a random mode — Floyd-Steinberg gives smooth gradients, while ordered dithering produces the regular cross-hatch pattern seen on classic Game Boy and CGA screens.

If you would rather not tune every setting, there are 20 one-click presets that bundle a sensible block size, shape, palette, and dither together. They include 8-Bit Retro, 16-Bit Classic, Minecraft, Mosaic, Halftone, Pointillism, Noir Pixels, Cross Stitch, and faithful Game Boy, NES, SNES, CGA, and EGA looks.

Comparing, refining, and exporting

A live preview updates as you adjust settings. You can view the original and pixelated versions side by side, drag a before/after slider, or show the pixelated result on its own, with zoom for inspecting individual blocks. An optional grid overlay marks the block boundaries, which is helpful when you are working toward an exact sprite resolution.

You don't have to pixelate the whole frame. Drawing a selection rectangle limits the effect to one region — useful for censoring a face, license plate, or piece of text — and the selection can be inverted so everything outside the box is pixelated instead.

When you are happy, export to PNG, JPEG, or WebP, with an adjustable quality setting for the lossy formats, or to SVG, which writes each block as a vector rectangle so the art scales without blurring. The tool also supports batch mode: upload several images, apply the same settings, and download all the pixelated results at once. Settings you like can be saved in your browser and reloaded later, so a house style is one click away on your next image.
