## What it is
Squoosh is a browser-based web app for compressing images using modern codecs like MozJPEG, WebP, and AVIF, with all processing done locally via WebAssembly. It lets users visually compare before/after quality and export smaller files without uploading anything to a server.

## Use cases
- compress images for the web without uploading them
- convert png or jpeg to webp or avif
- reduce image file size while keeping quality
- compare compressed image quality side by side
- batch-optimize images for faster page loads
- compress screenshots locally for privacy

## When to choose
- you need fast, private, one-off image compression in a browser
- you want to compare codec outputs visually before saving
- you cannot install desktop software or send files to a server

## When to avoid
- you need scripted or CI-based bulk image optimization (use a CLI like squoosh-cli or sharp instead)
- you need batch processing of thousands of images
- you need editing features beyond compression like cropping or filters
