From video to MP3 in three steps

The starting point for the whole converter cluster: drop any audio or video, pick what should come out, and take the file — no software, no sign-up, no limits.

  1. Step 1

    Upload your file

    Drag a video or audio file into the upload area, or click to browse your device. MP4, MOV, AVI, MKV, WebM, WAV, M4A and more all work.

  2. Step 2

    Choose MP3 and convert

    Pick MP3 as your output format — or M4A, OGG, WAV — set the bitrate, and hit Convert. The audio is extracted and encoded right in your browser, no upload.

  3. Step 3

    Download your MP3

    The moment conversion finishes you get the file — click to save it to your device. Fast, free, and nothing to install.

Convert any format to MP3

Strip the audio out of a video or shrink a heavy recording — every common format works, all on your device.

MP4 to MP3

Pull the soundtrack out of a video and keep just the audio — a fraction of the size, none of the quality lost.

MOV to MP3

Turn iPhone and Mac recordings — voice memos, interviews, lectures — into a clean MP3 anything can play.

AVI & MKV to MP3

Extract the audio track from Windows and desktop video formats without re-encoding the whole file.

WAV to MP3

WAV files run ten to fifty times larger than they need to. Shrink them to a portable MP3 that still sounds great.

M4A to MP3

Swap Apple's M4A for the one format every car, console, and player on earth understands.

Why MP3, and why in the browser

MP3 is still the most widely supported audio format in the world — every phone, car system, player, console, and editor plays it. And because the whole conversion happens locally, your files stay private: they never get sent to a server.

Which output format should you pick

MP3
Lossy. The universal choice — every phone, car, console and editor plays it. 128 kbps for speech, 192–320 kbps for music
M4A (AAC)
Lossy. Sounds better than MP3 at the same bitrate and is the native format across Apple devices
OGG (Vorbis)
Lossy and royalty-free. Well supported by browsers and Android; patchy on Apple hardware
FLAC
Lossless — bit-for-bit the original, at roughly half the size of WAV. Use it for archiving, not for sharing
WAV
Uncompressed PCM. The largest files and the safest input for editing and mastering
Extracting audio from video
Any video you drop is decoded and only its audio track is written out — you never need a separate video-to-audio step

Frequently asked questions

Is the converter really free?

Yes. No account, no email, no hidden fees, no conversion limits — it runs entirely on your own device.

Do my files get uploaded anywhere?

No. Conversion happens on your own device from start to finish — your file never leaves your computer or phone.

Can I pull just the audio out of a video?

Yes — that is what the converter does with any video file. The picture is discarded and only the audio track is encoded, so an MP4 or MOV comes back as MP3, M4A, OGG, FLAC or WAV.

Which format should I choose if not MP3?

M4A for Apple devices, OGG for the open web, FLAC when you need a lossless archive, WAV when the file is going into an editor. The table above compares them.

Which formats can I convert?

Most common video and audio formats in (MP4, MOV, AVI, MKV, WebM, FLV, WMV, MPEG, 3GP, M4V, TS, WAV, M4A and more) and MP3, M4A, OGG, FLAC, or WAV out.

What bitrate should I pick?

128 kbps is fine for speech and voice notes. For music, 192–320 kbps keeps it crisp. WAV output is lossless.

Does it work on my phone?

Yes — Windows, macOS, Linux, Android, and iOS, in any modern browser. Nothing to install.

Can I get a text transcript instead of audio?

Yes. SlayScribe transcribes audio and video into accurate text in 99 languages — start from the converter and hit “Transcribe it to text.”
