Extract audio from video online for free with VoxCraft. Upload an MP4, MOV, WebM or similar file and download the audio track as MP3 or WAV — no install, no account required on the free tier.
Creators use extraction when the video is only a container: screen recordings, camera interviews, Zoom exports, or phone clips where the picture is secondary. Once you have a clean audio file, you can denoise, transcribe, convert, or drop it into a podcast timeline without opening a full video editor.
Unlike desktop suites, this page is a single-purpose browser tool: separate the soundtrack, choose a practical format, download. Typical next steps on VoxCraft are noise reduction, transcription, or format conversion.
Respect copyright and platform rules: extract audio only from video you own or have rights to use. “Online MP4 to MP3” tools are often used for legitimate editing workflows, not for stripping commercial music from other people’s uploads.
How it works
- Upload your video (MP4, AVI, MOV, MKV or WEBM, up to 50MB).
- Choose an output format (MP3, WAV or OGG) and bitrate.
- Tap Extract audio and wait — larger files take longer.
- Download the resulting audio-only file.

Tips for better results
- Prefer WAV if you will denoise or edit further; use MP3 for smaller sharing files.
- If the video is huge, trim it in a video app first or expect longer upload times.
- After extract, normalize loudness before publishing if levels are uneven.
- For multi-track professional projects, a NLE still wins — this tool is for fast single-track extraction.
- Working with a particular video type? See MOV to MP3 (iPhone video), MKV to MP3 and WebM to MP3.
Frequently asked questions
Is extracting audio from video free?
Yes on the free tier within current limits, without required signup.
What video formats work?
Common containers such as MP4, MOV, and WebM are typical. If a file fails, convert the video in another tool or re-export from the original app.
MP3 or WAV — which should I pick?
WAV for further editing/denoise; MP3 for smaller distribution files.
Can I extract only part of the timeline?
This tool focuses on the full audio track. For a section, extract first then trim, or cut the video before upload.
Will this separate speakers or music beds?
No. It extracts the mixed audio track as recorded, not stem separation.
Is this legal for any YouTube URL?
Do not use extraction to infringe copyright. Work with files you own or are licensed to process.
What is a typical creator workflow?
Extract → optional denoise → transcribe or edit → publish. See also audio tools for YouTubers.
