Free Image to Pixel Art Converter Online

How to convert an image to pixel art

1. Drop your JPG, PNG, GIF, AVIF, BMP or WebP images onto the converter — or click "Choose files" to browse. You can add as many as you like.
2. Set Pixel size from 1 to 10. Size 1 keeps the finest grid that still reads as pixel art; size 10 gives the biggest, chunkiest pixels.
3. Set Quality to control the color palette. 100% keeps every color; lower values reduce the image to fewer colors for a classic retro look.
4. Use the gear icon in a column header to apply one pixel size or quality to every file at once, then adjust single files if needed.
5. Click Convert on one file or Convert all, preview the result, and download PNGs individually or all together as a ZIP.

Your images stay on your device — 100% private

This pixel art converter runs entirely in your browser. Your photos are read with the File API, pixelated on an off-screen canvas, and handed back to you as a downloadable PNG. Nothing is uploaded to a server, there is no account, no watermark and no limit on how many images you convert.

That matters for personal photos, client artwork and unreleased game assets. You can confirm it yourself: open your browser DevTools, switch to the Network tab and convert an image — you will see no file transfers. Converting an image does not need a network connection once the page has loaded.

What is pixel art — and how this tool creates it

This free online pixelator — a photo to pixel art converter, or pixel art maker if you prefer — pixelates any image in seconds without drawing a single pixel by hand.

Pixel art is digital art built from a visible grid of large square pixels, each one a single flat color. It comes from the screens of 8-bit and 16-bit consoles and early computers, where low resolution and a small color palette were hardware limits. Today it is a deliberate style used in indie games, avatars, emotes, album art and social media posts.

Turning a photo into pixel art takes two ideas working together: a coarse pixel grid and a limited palette. This converter exposes each as one slider, so you can dial in the look instead of guessing.

The conversion in three steps

• Downscale — the image is shrunk to a small grid (for example 64 × 48 cells). Each cell takes the averaged color of the area it covers, so details merge into clean blocks.
• Reduce colors — optionally, the colors in that small grid are merged into a limited palette with the median-cut algorithm.
• Upscale without smoothing — the grid is enlarged by a whole-number factor with interpolation switched off, so every cell becomes a crisp square and the result stays close to the original size.

Pixel size 1–10 — how big should the pixels be?

Pixel size sets how many cells the longer side of your image is divided into. Because the grid follows the image, the same setting gives a consistent look on a phone photo, a wide banner or a square logo. The scale runs in geometric steps — each step is about 20% coarser than the last — because the eye judges "chunkiness" by ratio, not by absolute difference.

The tool never makes a grid larger than the image itself, so a very small source simply stays as detailed as it already is. Size 1 is deliberately capped at 128 cells: beyond that point the result looks like a slightly blurry low-resolution photo rather than pixel art.

Quality — the color palette slider

A PNG is lossless, so "quality" here does not mean compression artifacts — it controls how many colors the pixel art may use. This is what real pixel art is about: classic consoles worked with palettes of 4, 16 or 256 colors, and that restriction gives the style its flat, graphic character.

Colors are chosen with median cut: the pixels are repeatedly split along the color channel with the widest range, and each final group is replaced by its average color. The palette therefore adapts to your image — a sunset gets oranges and purples, a forest gets greens — instead of using a fixed generic set.

Lower quality also gives a smaller PNG, because large areas of identical color compress far better. If file size matters — for a website, an emote upload limit or a game build — reduce quality before reducing the pixel size.

What people use pixel art converters for

• Game development — turn reference photos into backgrounds and tiles, or prototype an art style before drawing by hand. Game jams love fast placeholder art.
• Avatars and profile pictures — a pixelated portrait stands out on Discord, GitHub, Twitch and forums.
• Emotes and stickers — use sizes 6–8 with a limited palette to keep emotes readable at 28 pixels.
• Social media and posters — the retro look is popular for music, gaming and tech content.
• Privacy blurring with style — high pixel sizes hide faces and license plates while looking intentional rather than like a censor bar. For anything truly sensitive — passwords, ID numbers, small text — cover it with a solid box instead: light pixelation can sometimes be partly reversed.
• Icons and favicons — size 9–10 with a small palette gives crisp 16 × 16 style icons.

Tips for better pixel art from a photo

Start with a clear subject

Pixelation throws away fine detail, so images with one strong subject against a simple background survive best. Busy scenes turn into noise at coarse sizes. Crop tightly before converting — the grid is spread over the whole image, so every pixel spent on empty space is wasted.

Boost contrast first

Flat, low-contrast photos produce muddy pixel art. A small contrast or saturation boost in any editor before conversion gives the palette distinct colors to work with.

Match size and quality

• Coarse pixels (7–10) look best with a limited palette (quality 30–60%).
• Fine pixels (1–3) need more colors (quality 80–100%) or smooth areas get visible banding.
• For a "GameBoy" feel try pixel size 4–5 with quality 10–20%.

Keep transparency

Transparent PNG and WebP files keep their transparency. When you lower the quality, edges become hard — a pixel is either solid or fully transparent, as in real sprite art — so there are no half-transparent halos.

How to show pixel art crisply on a website

Browsers smooth images when they scale them, which blurs pixel art. If you display a small pixel image larger than its natural size, tell the browser to use nearest-neighbor scaling with the CSS property below. The PNG files from this tool are already upscaled with sharp edges, so this is only needed when you resize them further.

.pixel-art {
  image-rendering: crisp-edges;    /* fallback for older Firefox */
  image-rendering: pixelated;      /* Chrome, Edge, Safari, current Firefox */
}

How pixelation works in your browser

The converter uses only built-in browser APIs — no server and no external libraries for the conversion itself. The core of it is two canvas draws: one to shrink the image, one to enlarge it with smoothing switched off.

// 1. Shrink to a small grid — smoothing averages each cell
small.getContext('2d').drawImage(bitmap, 0, 0, cellsX, cellsY)

// 2. Enlarge by a whole number, no interpolation → crisp square pixels
const ctx = output.getContext('2d')
ctx.imageSmoothingEnabled = false
ctx.drawImage(small, 0, 0, cellsX * scale, cellsY * scale)

// 3. Export a lossless PNG
output.toBlob(blob => download(blob), 'image/png')

Very large photos are halved repeatedly before the final shrink, which averages many source pixels into each cell instead of sampling sparsely and producing noisy results.
