BC64 PixelStudio — Pixel Art Editor for macOS

Features

🖌️

Drawing Tools

Pencil, line, rectangle, circle, fill, and eraser — all pixel-perfect with adjustable sizes.

📚

Layer System

Professional layers with blend modes (Normal, Multiply, Screen, Overlay) and per-layer opacity.

🔳

Pixel Grid & Presets

Grid overlay with C64 sprite (24×21), C64 char (8×8), and custom presets. Grid snap for pixel-perfect selections.

📐

Resize & Upscale

Resize with pixel multipliers (2×–32×) or exact mm+DPI. Nearest-neighbor interpolation for crisp pixel art.

✨

Selection Tools

Rectangle, ellipse, lasso, and magic wand selections. Copy to clipboard (⌘C) or as merged layers (⌘⇧C).

🎯

Magic Wand

Select by color with adjustable tolerance, contiguous and non-contiguous modes, feather support.

📋

Clipboard Integration

Copy layer or merged image to system clipboard (⌘C / ⌘⇧C). Paste images from clipboard (⌘⇧V). Open multiple windows (⌘⇧N).

🔄

Symmetry Drawing

Mirror drawing horizontally, vertically, or both — ideal for sprite creation.

💾

File Formats

Native .bc64ps format preserving layers, zoom, grid, selection state. Import PNG, JPEG, GIF, TIFF. Export PNG/JPEG/WebP with quality and scale.

🤖

AI Integration

OpenAI & Claude API support for background removal, image generation, inpainting, upscale, design assistant, and more.

✂️

Crop & Clip

Crop canvas to selection. Clip all layers to canvas bounds. Resize with size limit protection (max 16384px).

How It Works

Create or Import

Start a new canvas (Cmd+N) or import an existing image (Cmd+I).

Edit

Draw, paint, and manipulate with layers, selections, grids, and symmetry tools.

Resize & Scale

Upscale sprites with nearest-neighbor interpolation for pixel-perfect results.

Export

Save as PNG or JPEG with custom quality and scale factor — ready for print or web.
