FAQ

Is my video file uploaded to any server?Show
No. All conversion happens locally in your browser using WebAssembly. Your video file never leaves your device.
What audio formats are supported for output?Show
You can convert to MP3, AAC, and OGG formats. MP3 is the most widely compatible, while AAC offers better quality at lower bitrates.
Can I extract only a portion of the audio?Show
Yes! You can set custom start and end times to extract only the audio segment you need from the video.
What video formats are supported as input?Show
The tool primarily supports MP4 files, but most common video formats (AVI, MOV, MKV, etc.) should work as well.
How do I choose the right audio quality?Show
For music: use 192-320 kbps. For speech/podcasts: 128 kbps is usually sufficient. Higher bitrates mean better quality but larger file sizes.
