I built Squash because I kept running into the same frustration — every image compression tool I used was uploading my files to some server I knew nothing about. That felt wrong, especially when working with client assets or anything remotely sensitive.
So I built Squash to do everything locally. Your images never leave your browser — compression, format conversion, resizing — all powered by WebAssembly running entirely on your machine.
What it does:
Compress to JPEG, WebP, and AVIF with a live quality slider
Resize images with max-width/max-height constraints
Before/after compare view so you can see exactly what you're trading off
Batch process multiple images at once
No account, no watermarks, no uploads — ever
The hardest part was getting AVIF conversion to work reliably across browsers without a server fallback. Ended up leaning on OffscreenCanvas in a Web Worker so the UI never blocks, even on large batches.
Would love your feedback — especially on formats you'd want supported or workflow features that would make this actually useful day-to-day.
Love that everything runs in the browser, no uploads needed. The drag-and-drop feels instant and the format options are exactly what I'd want without any clutter.
The fact that everything runs locally in the browser without a single upload feels like the right call for something handling user images. Clean, focused, and respects privacy by default.
how does it handle batch processing if everything runs locally in the browser, does it get slow with like 50+ large photos at once?
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.
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.
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.
