About Scrunch

Scrunch is a free web tool that converts and compresses many images at once into WebP, AVIF, JPEG or PNG. It was built to remove the hassle of compressing images one by one.

What makes it different

• Many at once — drop several images, set format and quality once, convert in bulk.
• No server upload — everything runs in your browser, so images never leave your device.
• Before/after compare — click a result to compare original and compressed with a slider.
• One-click ZIP — download results individually or all at once.

How it works

Scrunch uses your browser's image decoding plus open-source codecs compiled to WebAssembly (jSquash, based on Google Squoosh). Heavy encoding runs in parallel web workers so many images process quickly.

Cost
