What video formats are supported for audio extraction?

This tool supports all major video formats including MP4, AVI, MOV, MKV, WEBM, FLV, and WMV. Basically any video file your browser can play. MP4 with H.264 encoding provides the best compatibility and processing speed.

What audio quality can I expect and what formats can I choose?

The extracted audio quality depends on the original video's audio track. Two output formats are available: WAV (lossless, best quality, larger file size) and WebM/Opus (compressed, smaller file). For music, choose WAV. For voice recordings, the compressed format is sufficient.

Is my video uploaded to a server?

No. This tool is 100% client-side. Your video file is processed locally in your browser using the Web Audio API and HTML5 video elements. The video never leaves your device, ensuring complete privacy and security.

Why is the extracted audio shorter than the video?

The extracted audio duration should match the video duration. If you notice a discrepancy, it may be because of silent sections at the end being trimmed by the audio encoder. If the issue persists, try using Chrome or Edge browser.

How long can the video be?

There is no strict time limit, but videos longer than 30 minutes may require significant memory and processing time. Videos under 15 minutes process fastest. For very long videos, consider splitting them first. If the browser runs out of memory, try a shorter clip.

Can I batch convert multiple videos?

Currently this tool processes one video at a time. For batch processing multiple videos, we recommend using desktop tools like FFmpeg (free, open-source command line tool) or Format Factory (free GUI application).
