Media workflows

What can you do with video tools?

The video section brings common compression, conversion, trimming, caption, and extraction tasks into a focused browser workflow.

Media processing uses a local WebAssembly engine, so source files remain on the device while the browser creates the requested output.

Compress and convert video for web, email, and messaging delivery.
Trim clips, remove audio, capture frames, and adjust playback speed.
Extract soundtracks or permanently render SRT captions onto video.
