Show HN: Toolbox: Run FFmpeg, Imagemagick, 7Zip and Friends in the Browser

I got sick of sketchy online converter sites that phone home and may keep your files and walking non-technical friends through brew/apt/choco installs every time they need ffmpeg or imagemagick and telling them what command to run.

So I built Toolbox, a 100% open source site that compiles my most-used command-line tools to WebAssembly and runs them fully client-side: - FFmpeg (video + audio) - ExifTool (metadata) - 7-Zip (archive/zip/rar/7z) - ImageMagick - Pandoc

Roadmap: - Batch mode - Shareable presets. Complex commands can be saved as URLs so you can send a one-click recipe to a friend, inspired by cyberchef - GPU acceleration via WebGPU someday? (mostly looking at ffmpeg, maybe with WebCodec)

I’d love feedback, bug reports, and requests for other tools. If it helps you ditch shady sites or long install docs, mission accomplished.
