  ## 🎨 Convert

  - Drop any image. Pick a canvas size:

    - **Square**: 16×16 / 32×32 / 64×64

    - **Portrait (9:16)**: 36×64 / 45×80 / 72×128

    - **Portrait (4:5)**: 32×40 / 48×60 / 80×100

  - **Palette limiting** — clamp output to **4 / 8 / 16 / 32 / 64** colors, or keep full color.

  - **Built-in palette presets** — Game Boy, GB Pocket, PICO-8, CGA, NES, 1-bit, Sepia.

  - **Bayer 4×4 dithering** — smooth gradients even on tiny palettes.

  - No image handy? Try one of the four built-in sample images.

  ## ✏️ Edit

  A full pixel editor is built in — you don't need a separate program.

  - **Tools**: pencil, eraser, eyedropper, bucket fill, line, rectangle, ellipse, lasso select.

  - **Layers + frames**, Aseprite-style.

  - **Mirror draw** (horizontal / vertical) and **onion skin** for animation.

  - **Ctrl + wheel** to zoom the canvas. Click the preview to enlarge.

  - **Ctrl + Z / Ctrl + Y** for undo / redo.

  ## 💾 Export

  - **PNG** — single frame, sprite sheet, or one PNG per frame (folder save).

  - **Animated GIF** — scale 1× to 8×, fps 2 to 15, with transparent background.

  ## 🔒 Privacy

  Your images never leave your computer. The whole tool is a single HTML file — open it once and it works offline. No tracking, no analytics.   

  ## 🖥️ Best on desktop

  Designed for keyboard + mouse. Phones technically work, but the editor is cramped on small screens.
