Compress & Convert Images
Image optimizer — no uploads, all in-browser
Squash is a free, browser-based image optimizer that compresses and converts images to WebP, AVIF, and JPEG. No uploads, no watermarks, 100% private.
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.
