What video formats are supported?

Most common formats: MP4, WebM, AVI, MOV, MKV, FLV, WMV, M4V. The tool uses FFmpeg which supports virtually all video codecs.

What audio formats can I export?

MP3 (most compatible), AAC/M4A (better quality at same bitrate), WAV (lossless, larger file), OGG Vorbis (open format).

Why does it take a moment to start?

The FFmpeg WebAssembly engine (~30 MB) downloads on first use and is cached for future visits. After the initial load, conversions start instantly.

Is there a file size limit?

No hard limit — it depends on your device's available memory. Typical devices handle files up to 500 MB–1 GB comfortably.
