Hand-crafted pixel art assets for commercial use
Pixels Toolkit is a free desktop app for pixel art processing. It converts upscaled or AI-generated art into production-ready pixel sprites by detecting pixel grids and cleaning them to true resolution. Version 1.2.1 adds bulk processing for entire folders — apply color merge, outline, alpha normalization, background removal, and auto-downscale across all images with a single action. Originals are backed up with full revert support. Also includes palette normalization, outline generation, and sprite sheet packing with JSON metadata. Available for Windows (.msi), macOS (.dmg universal), and Linux (.AppImage, .deb). Built with Tauri and Rust. Free for personal and commercial use.
Open Pixels Toolkit, add your images, and use Smart Downscale. The app detects the underlying pixel grid in upscaled artwork — even when blurred by anti-aliasing or color noise — and cleanly reduces it to true pixel resolution. Process one image or batch hundreds. Settings persist per project so repeat workflows are instant.
