A lecture, a podcast published as video, an interview recording, a song in a music video — half the time you only need the sound. An MP3 is a fraction of the size, plays in every music app, keeps working when the screen is off, and slots into an editing timeline or a transcription tool without dragging the picture along. Upload a video above, pick a quality, and download the audio as an MP3 — the picture is discarded, nothing else changes.
Higher bitrate means better sound and a bigger file. Match the choice to what you are extracting, not to a bigger-is-better habit.
| What is inside the video | What matters | Pick this |
|---|---|---|
| Speech — lectures, meetings, interviews | Clarity of voice; file size barely matters at these lengths | 128 kbps — perfectly clean for talking |
| Podcasts & screencasts with narration | Long listens where a slightly richer voice helps | 160 kbps — the default on this page |
| Music — songs, performances, soundtracks | Cymbals and bass reveal low bitrates fast | 320 kbps — the top of the MP3 range |
| Soundbites & samples for editing | You will re-encode it later anyway | 160 kbps — good middle ground |
| Ringtones & alarms | Ten seconds of audio — size is irrelevant | 320 kbps — keep every bit |
All three presets (128 / 160 / 320 kbps) are available on this page. The step from 128 to 320 roughly triples the file — for spoken content you will not hear the difference, for music you might. Limits checked October 2026.
Three steps in the browser — no software, no account needed for a first conversion.
Drop in an MP4, MOV, WebM, MKV or AVI. The preview loads in the page so you can confirm it is the right file before converting.
Pick 128, 160 or 320 kbps using the quality buttons. 160 suits most uses; go up for music, down for long speech.
Press Convert to MP3 and the audio track is extracted in the cloud. Download a standard MP3 that plays in any music app, car stereo or phone — no watermark, nothing to install.
MP3 size ≈ bitrate × duration. Use this before you convert so the result is not a surprise.
| Audio length | At 128 kbps | At 320 kbps |
|---|---|---|
| 30 seconds | ≈ 0.5 MB | ≈ 1.2 MB |
| 1 minute | ≈ 1 MB | ≈ 2.4 MB |
| 5 minutes | ≈ 5 MB | ≈ 12 MB |
| 10 minutes | ≈ 10 MB | ≈ 24 MB |
| 1 hour (lecture) | ≈ 58 MB | ≈ 144 MB |
| Full video of any length | Scales linearly — double the time, double the file | Same rule, three times the rate |
Numbers assume constant-bitrate MP3 with no silence optimization. 160 kbps — the default here — sits between the first two columns: about 1.2 MB per minute.
Conversion here is a straight extraction: the video stream is dropped, the audio stream is decoded once and re-encoded as MP3. A few things worth knowing before you start.
Screen recordings without a microphone track have nothing to extract. This page checks the file after upload and tells you before the job runs, instead of failing halfway through.
The source audio (usually AAC) is decoded and compressed again into MP3. At 320 kbps the difference from the original is inaudible for almost everyone; at 128 kbps speech still sounds natural.
Need just the middle five minutes of a two-hour recording? Trim the video first, then convert — or convert the whole thing and cut the MP3 afterwards. Both paths use the tools linked below.
Guests convert one video per day up to 250 MB. Signed-in plans handle files up to 1 GB (larger on paid tiers) with monthly credits covering the runtime.
