A quick introduction to PixelTool: why image processing stays in your browser and how to create pixel art you like.

PixelTool is a free, browser-based pixel art tool. Upload an image, adjust the pixel size and color count, then preview the result in real time and export it when it looks right. No account is needed, and your image never leaves your device. This post introduces the thinking behind PixelTool and its main features.

Why we built it

Most pixel art tools fall into two camps. Desktop apps are powerful but slow to launch and lock you into a single machine. Web tools are convenient but usually upload your images to a server, which is a privacy and latency tax. PixelTool keeps all processing in the browser, so:

  • Your image never leaves your device
  • Latency is whatever your CPU is, not your network
  • The whole thing works offline once the page is loaded

What it does today

PixelTool’s editor is built around three controls, because that’s all 90% of pixel art actually needs:

  1. Pixel Block Size — how coarse the resulting pixels are. Small values stay close to the original; large values give a stronger retro vibe.
  2. Max Colors — reduces the palette from 256 (original fidelity) down to 2 colors for a strict 1-bit look.
  3. Max Output Size — picks the export resolution, from 128px up to 2048px, all the way up to the original.

The preview uses the same pixel-grid canvas the export uses, so what you see is what you get. There’s no separate “render” pass.

Exporting your art

Two formats cover most needs:

  • PNG for sharing and web use
  • SVG for crisp scaling — drop it into a game, blow it up to print, and the pixels stay razor sharp

Both run through the exact same quantized pixel grid as the preview, so there are no surprises at export time.

What’s next

PixelTool will continue to evolve through new features, performance improvements, and refinements to the editing experience. If there is a workflow or export option that would make the tool more useful for you, let us know.

Try it now

To try PixelTool, upload an image on the home page. Choose a pixel size, lower the color count a little at a time, and export when the preview feels right. Every adjustment updates in real time.
