What Is a Video to MP3 Converter?
A video to MP3 converter extracts the audio track from a video file and saves it as a standalone audio file. This is useful when you want the sound from a video — a song from a music video, dialogue from a lecture, or background music from a clip — without the video itself taking up space.
Most online converters upload your video to a server, which means long upload times for large files and trusting a third party with your content. AudioTrick runs entirely in your browser using WebAssembly. Your video never leaves your device — extraction is instant, completely private, and works offline after the first load.

- Save storage space — an MP3 is 10-50x smaller than the original video file.

MP3 vs AAC vs WAV: Which Format to Choose?
| Format | Quality | File Size | Best For |

Frequently Asked Questions
Is it safe to extract audio online?
Yes. AudioTrick processes everything in your browser using WebAssembly. Your video is never uploaded to any server — extraction happens entirely on your device. We don't store, access, or transmit your files.
What video formats are supported?
MP4, MOV, MKV, and WebM. These cover virtually all common video formats from phones, cameras, screen recorders, and downloads. Output formats include MP3, WAV, AAC, and OGG.
Can I extract audio on my phone?
Yes. AudioTrick works on any modern browser — Safari on iPhone, Chrome on Android, and all desktop browsers. For very large videos (over 200 MB), a desktop browser is recommended for best performance.
Does extracting audio reduce quality?
If you enable "Keep original audio track", the audio is copied bit-for-bit with zero quality loss — it's the fastest option too. When converting to a different format like MP3, some quality loss occurs during re-encoding, but at 320 kbps it's virtually indistinguishable from the original.
What if the video has no audio?
If the video file contains no audio track, the extraction will fail with a clear error message. This can happen with some screen recordings, animated GIFs converted to video, or videos where audio was intentionally removed.
What's the file size limit?
500 MB. Since everything runs in your browser, very large files may use a lot of memory. If you experience issues, close other tabs and try again. For the fastest extraction, enable "Keep original audio track".
Why is the extracted audio out of sync?
This is extremely rare with direct extraction. If you experience sync issues, try using the "Keep original audio track" option which copies the audio without re-encoding. If the issue persists, the source video may have variable frame rate or a corrupted container.
Can I use this to convert downloaded videos?
Yes. You can extract audio from any video file on your device — downloaded videos, screen recordings, camera footage, and more. Simply drop the file into the upload zone. The file never leaves your browser.
What audio formats are supported?
MP3, WAV, OGG, FLAC, M4A, AAC, and WebM. The output is always a 320 kbps MP3 file.
Is my audio uploaded to a server?
No. All processing happens locally in your browser using the Web Audio API. Your files never leave your device.
How good is the audio processing quality?
We use the same techniques found in professional audio software: convolution reverb with real impulse responses, phase vocoder time-stretching, HRTF-based spatial audio, EBU R128 peak limiting, and LUFS loudness normalization. What you hear in the preview is exactly what you get in the export — we guarantee preview/export parity across every tool.
