# Image Compressor (Web)
In-browser image compression, powered by Squoosh.
## How it works
Squoosh is a pure-client SPA — all encoding runs in your browser via WebAssembly (libwebp, libavif, jpeg-xl, MozJPEG, OxiPNG, ...). **Your images never leave your browser** — there is no server-side image processing.
## Features
- 7 output codecs (MozJPEG, WebP, AVIF, JXL, OxiPNG, WebP2, plus passthrough)
- Fine-grained encoder controls per codec
- Side-by-side before / after viewer with split slider
- Batch resize
- Drop in images, drop out compressed copies
- File-size + PSNR / SSIM quality metrics
## Packaging
Multi-stage build: Node clones Squoosh, runs `pnpm install` + `pnpm build`, then nginx serves the static bundle.
## CONFIRM-AT-BUILD
Squoosh's build command + output dir vary between major versions; verify against the chosen tag.
