Frequently Asked Questions
- What video formats are supported?
- You can convert between MP4, WebM, MOV, AVI, MKV, OGV, and FLV formats. You can also extract audio from any video as MP3, WAV, OGG, AAC, or FLAC.
- How does browser-based video conversion work?
- We use FFmpeg compiled to WebAssembly (FFmpeg.wasm), which runs entirely in your browser. The first time you convert, it loads a ~30MB engine. After that, conversions are fast and fully offline.
- Are my videos uploaded to a server?
- No. All conversion happens locally in your browser using FFmpeg.wasm. Your videos never leave your device — we have zero access to your files.
- How long does video conversion take?
- It depends on the file size and format. A 1-minute 1080p video typically converts in 30-60 seconds. Shorter clips and audio extraction are much faster. Browser-based conversion is slower than native apps but keeps your files private.
- Can I extract audio from a video?
- Yes! Drop any video file and select an audio output format (MP3, WAV, AAC, OGG, or FLAC). The audio track will be extracted without any quality loss.
- Is there a file size limit?
- There's no hard limit, but very large files (over 500MB) may be slow or run into browser memory limits. For best results, keep files under 200MB.
