## What it is
Squish is a browser-based batch image compression tool that uses WebAssembly codecs to compress and convert images entirely client-side. It supports AVIF, JPEG, JPEG XL, PNG, and WebP with quality adjustment, drag-and-drop, and no server uploads.

## Use cases
- compress a batch of images without uploading them to a server
- convert PNG photos to WebP or AVIF for the web
- reduce image file sizes before uploading to a website
- optimize images locally for privacy
- batch resize quality of screenshots for documentation

## When to choose
- you need client-side image compression with no uploads
- you want modern codecs like AVIF and JPEG XL in the browser
- you need batch processing with a simple drag-and-drop UI

## When to avoid
- you need CLI or server-side automated compression pipelines
- you need extremely large-scale or scripted batch workflows
- you need editing features beyond compression and format conversion
