Show HN: LocalSquash – A local web UI for FFmpeg.wasm

Hi HN,

I built LocalSquash to solve a recurring annoyance: needing to quickly compress a video or convert a HEIC photo, and not wanting to upload personal files to sketchy, ad-ridden conversion sites. Don't want to download a desktop app like Handbrake for quick, trivial tasks.

LocalSquash runs ffmpeg.wasm entirely locally in your browser. You drag and drop a file, tweak simple sliders, crop and/or trim, and it processes offline.

It’s completely free and processes entirely on your machine.

I’d love your feedback. What are your most frequently used FFmpeg commands? I’d love to turn them into 1-click presets.
