Is JPG the best format to convert to pixel art?

JPG works well for photos because the file already stores smooth color gradients. Pick a smaller block size (4-8) to keep detail, and enable dithering to recover shading in dark areas.

Do JPG compression artifacts affect the pixel art result?

Heavily compressed JPGs can show blocky noise that becomes extra color speckles after conversion. Use a block size of 8 or higher, or a limited palette like 8-bit (PICO-8), to smooth those artifacts away.

Can I convert a JPG without uploading it?

Yes. The conversion runs entirely in your browser — the image is decoded locally with Canvas and never leaves your device.

tips

Getting clean pixel art from a JPG photo

JPG photos are the classic input for pixel art because they already contain smooth gradients. Start with a block size of 8 for bold silhouettes, or 4 if you want to keep facial features and small details. High-contrast subjects with one clear focal point convert best — busy backgrounds turn into noisy blocks that dilute the pixel look. If the result feels muddy, try the 8-bit (PICO-8) palette with dithering on: the 16-color limit forces clean color bands and the error diffusion recovers shading that plain quantization would lose.

when to use

JPG vs PNG vs WebP for pixel art

Every format converts, but they behave differently. JPG is the best match for photos: it compresses color smoothly, and small artifacts disappear once you downsample to blocks. If your source is a logo or sprite with transparency, use the PNG converter instead — it preserves the alpha channel. For modern web images, the WebP converter handles the same workflow. And if your goal is a Minecraft block build, use the Minecraft build planner for material counts and blueprints.

blocks

Match the block size to the subject

Portraits keep shape at 8-16 blocks; logos and icons read best at 24-32.

palette

Full color keeps realism

Use full color for photo-real pixel art, or 8-bit / Game Boy palettes for a retro look.

export

Download a sharp PNG

Output is scaled with nearest-neighbor so block edges stay crisp at any download size.
