Convert MP4 to MP3 Online
To convert an MP4 to MP3, upload the video below, select MP3 as the audio format, and download the extracted track — the tool strips the video and keeps only the sound.
Music in a concert clip, a lecture you want to replay on a run, a podcast episode published as video — plenty of audio worth keeping arrives wrapped in an MP4. Extracting it as MP3 gives you a small file that plays in any music app, fits on any device, and skips the video data you never needed.
How it works
- 1
Upload the MP4 video
Drop in the video that contains the audio you want — up to 500 MB. Phone recordings, downloaded files, and editor exports all work.
- 2
Choose MP3 as the format
Select MP3 from the output options. WAV and AAC are also available if a specific app or workflow prefers them.
- 3
Download the audio file
Start the extraction and download your MP3 moments later. Add it to a playlist, a podcast app, or a voice-notes folder.
Why use Video-Matic
Tiny files, same sound
Dropping the video stream shrinks the file dramatically — a lecture that was hundreds of megabytes becomes an MP3 you can email.
Plays absolutely everywhere
MP3 is the most universally supported audio format ever made; the extracted track works in every player, car stereo, and phone.
One credit per extraction
Audio extraction costs a single credit, and the 3 free credits at signup cover your first three files.
Nothing retained
The uploaded video and the extracted MP3 are wiped from EU-hosted storage within 24 hours automatically.
Frequently asked questions
Does converting MP4 to MP3 lose audio quality?›
MP3 is a compressed format, so the extraction is not bit-perfect, but the quality is more than adequate for speech, lectures, and casual music listening — most people cannot tell the difference. If you need the highest fidelity for editing or archiving, choose WAV output instead, which is lossless.
Can I extract just part of the audio?›
The extractor processes the full length of the uploaded video. To keep only a section, trim the video first with the Trim tool — it cuts without re-encoding, so it is fast — and then run the trimmed file through the MP4 to MP3 conversion. Two quick jobs, two credits total.
Is this MP4 to MP3 converter really free?›
Yes, for your first three files: signup gives 3 free credits and each extraction costs 1 credit. There is no watermark concept in audio and no branding added — you get a clean MP3. If you need more extractions later, one-time credit packs are on the pricing page; no subscription exists.
What happens to my video after the audio is extracted?›
It is deleted automatically within 24 hours, along with the MP3 you generated. Processing happens on servers in Paris, in the EU, and files are only accessible from your own account — a GDPR-friendly setup for personal recordings, meetings, and voice memos.
