Snap

A little image toolbox.

Snap is a local-first desktop application built for editing and compressing images.

Features

• Quick input: Drag and drop images right into the window, open via file browser, or paste directly from your clipboard.
• Non-destructive crop & transforms: Freeform cropping, aspect-ratio locks (1:1, 16:9, 4:3, 3:2, 9:16, 4:5), 90-degree rotations, and horizontal/vertical flips.
• Precise resizing: Scale by exact pixel dimensions or percentages with aspect-ratio locking and resampling.
• Format conversion & compression: Convert between WebP, PNG, and JPEG with live quality controls and before/after file size feedback.
• On-device AI background removal: Isolate subjects and create transparent cutouts locally using RMBG 2.0, Lucida ONNX, BiRefNet HR Matting (2048×2048), or FeyNobg ONNX, accelerated via NVIDIA CUDA GPU with automatic CPU fallback.
• AI neural upscaling: Enhance image resolution 2× or 4× using Real-ESRGAN with GPU acceleration and memory-bounded tiled processing. Run a second pass on the result to go further, up to an 8000px long edge.
• Low-light and exposure correction: Rescue dark or badly exposed photos with the Illumination Adaptive Transformer. Three checkpoints (LOL-V1, LOL-V2, and Exposure Errors) and each is under half a megabyte.
• Black-and-white colorization: Add color to old photos with DDColor. Only the color is predicted, so the original lightness, grain, and detail stay exactly as shot.
• Object removal: Click an object in the Select tab, hit Remove, and LaMa paints over the gap with whatever belongs there. Runs on a 92.6 MB ONNX model downloaded on first use. Everything outside your selection is left exactly as it was.
• AI image restoration: Repair noisy, blurry, and artifact-heavy images with NAFNet and SCUNet. Three tasks, each with its own model: general restore, denoise, and deblur. Runs on the same tiled, GPU-accelerated pipeline as upscaling.
• Metadata privacy: Inspect EXIF information and strip metadata with one click upon export.
• Live comparison: Toggle between your working edits and the original image in real time.
• Safe exports: Snap preserves your original image files and saves your edits to a separate destination.

Getting Started

Prerequisites

• Node.js (version 18 or newer)
• Rust and Cargo
• Linux build libraries (if on Linux): libgtk-3-dev, libwebkit2gtk-4.1-dev, libayatana-appindicator3-dev, librsvg2-dev

Installation & Development

Clone the repository and install dependencies:

git clone https://github.com/pinkpixel-dev/snap.git
cd snap
npm install

Run Snap in desktop development mode:
