MP4 to MP3 converter
Pull the audio out of a video and save it as an MP3. The conversion runs inside your browser, so the file is not uploaded anywhere and there is no queue: choose the file, pick the quality, download the result.
This page needs JavaScript for the tool itself. Open it in a browser to use it.
How it works
Drop an MP4, MOV or M4A file on the page. Your browser decodes its audio track, this page resamples and mixes it the way you asked, and an encoder running in a background thread writes the MP3. The finished file is offered for download from your own device. Nothing is sent to BeatRootRaga.
Choose the quality
Bitrate sets the size and quality of the MP3: 128 kbps is the usual choice for speech and casual listening, 192 kbps is a good default for music, 320 kbps is the best MP3 can do. Sample rate stays the same as the source unless you change it; 44100 Hz is the CD and streaming standard, 48000 Hz is what video uses. Mono mix-down halves the size and suits voice recordings.
WAV or AIFF instead of MP3
If the audio is going into an editor, a DAW or a mastering session, save it lossless: WAV at 16-bit, 24-bit or 32-bit float, or AIFF at 16-bit or 24-bit. There is no point converting a lossy source to a higher bit depth for quality, but it keeps an editor from re-encoding it again.
What the browser can read
Any file the browser itself can play: MP4 and MOV with an AAC or MP3 audio track, M4A, MP3, WAV, AIFF, FLAC and OGG. Very long recordings are limited by your device's memory, since the whole track is decoded before it is encoded; a phone manages a typical song or podcast episode, a laptop manages hours.
From the label's own toolbox
BeatRootRaga is an independent label. Converting reference tracks, video rushes and voice notes into files a session can use is daily work, and this page is the converter the label uses itself, put online for anyone. When the audio is a song you want to practise, the vocal remover and the stem splitter take it further.

All guidesRaga Yaman (Kalyani)
Yaman is a seven-note Hindustani raga, a melodic framework, with a raised fourth; Kalyani shares its scale but uses different phrasing and ornaments. Traditionally associated with evening, Yaman can sound serene or devotional; hear its character through Ni Re Ga, starting below Sa, the home note.
Thaat and melakarta explained
A thaat in Hindustani music and a melakarta in Carnatic music are seven-note parent scales used to organise ragas, the melodic frameworks musicians perform. Hindustani music uses 10 practical categories, while Carnatic music uses 72 allowed scale combinations; these help identify note relationships, not a raga’s phrases or character.
Raga vs scale: what Western musicians get wrong
A raga adds rules for movement, emphasis, identifying phrases and ornamentation to a scale or mode, a scale with a home note. Producers lose its identity when they treat it as a note list, ignore its tuning and phrasing, or let changing chords reshape the melody’s meaning.
Raga Kirwani (Keeravani)
Kirwani is a raga, a musical framework, using C D Eb F G Ab B when Sa, its home note, is C. Heard in concerts, light classical music and film scores, it often suggests longing; listen for Ab rising to B, then C.
Raga Hamsadhwani
Hamsadhwani is a five-note raga from the Carnatic tradition, using Sa, Re, Ga, Pa and Ni, or C D E G B with Sa as C. It often opens Carnatic concerts; hear its bright, devotional character by playing the notes over C and G, noticing B resolving to C.
Raga Charukeshi (Charukesi)
Charukeshi comes from Carnatic music and uses Sa, Re, Ga, Ma, Pa, lowered Dha and lowered Ni. Heard in concerts, light music and film scores, its bittersweet character is clearest in the descent from lowered Ni through lowered Dha to Pa.
Questions people ask
Is the MP4 to MP3 converter free?
Yes. There is no charge, no account and no watermark. The conversion happens in your browser, so there is no server cost to pass on.
Is my file uploaded?
No. The file is read by your browser on your device, converted there, and the result is saved from there. Close the tab and nothing remains anywhere.
Which bitrate should I choose?
192 kbps is a good default for music, 128 kbps for speech, 320 kbps when size does not matter. A 4-minute track is about 6 MB at 192 kbps and 10 MB at 320 kbps.
Can I keep the original sample rate and channels?
Yes, both default to the same as the source. You can also set any rate from 8000 Hz to 48000 Hz for MP3 (up to 96000 Hz for WAV and AIFF) and mix down to mono or force stereo.
Why did my file fail to convert?
The browser could not decode it. Most often the video has no audio track, or the audio is in a codec the browser does not play (some MOV files use PCM or ALAC that only Safari reads). Try another browser, or export the audio from the source app first.
Is there a file size limit?
No fixed limit. The whole track is decoded into memory before encoding, so the practical limit is your device: a phone handles a typical song or episode, a laptop handles hours of audio.
