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
