Squash is a free, browser-based image optimizer that compresses and converts images to WebP, AVIF, and JPEG. No uploads, no watermarks, 100% private.

How does it handle really large batch uploads, like 50+ high-res images at once? Curious if it stays snappy in the browser or if things start to crawl.
how does it handle batch processing if everything runs locally in the browser, does it get slow with like 50+ large photos at once?
One thing that would push this over the top for me is bulk folder handling. Dragging in a whole directory of mixed JPEGs and PNGs and getting back a zip of optimized AVIFs (or whatever format I pick) would save a ton of clicks.
Ran a few photos through it and the WebP output was noticeably smaller than what I usually get, all without anything leaving my browser which is a nice touch.
