## What it is
A JavaScript library that compresses jpeg, png, webp, and bmp images directly in the web browser by reducing resolution or storage size. It supports non-blocking multi-threaded compression via web workers and is designed to shrink images before uploading to a server.

## Use cases
- compress images before uploading to save bandwidth
- reduce image file size in the browser
- resize images client-side before upload
- compress user-uploaded photos in a web app
- shrink jpeg png webp files in the browser
- non-blocking image compression with web workers

## When to choose
- you need client-side image compression before upload
- you want to reduce bandwidth by shrinking images in the browser
- you need a simple async API usable with React, Angular, or Vue
- you want multi-threaded compression that doesn't block the UI

## When to avoid
- you need server-side or Node.js image compression
- you need advanced editing like cropping or filters
- you require formats beyond jpeg, png, webp, or bmp
