よくある質問

Are my videos uploaded?

Never. Processing runs entirely in your browser using FFmpeg WebAssembly.

Why is it slow?

Video encoding is CPU-heavy. Expect roughly 1–5× the video's duration for encoding. First-time load also downloads ~30 MB of FFmpeg (cached after).

What's the file size limit?

Depends on your device's memory. Files up to ~1 GB usually work; multi-GB files may crash the tab.
