Local · No uploadsPull audio from one or more MP4, MKV, MOV, AVI or WebM videos, then export MP3, AAC, WAV or FLAC. Batch-extract full tracks, trim segments, edit title, artist and cover art, and preview results before download. Useful for ringtones, lectures, podcasts, interviews and sound effects; all processing runs locally.
Quick Answers
- Audio extraction keeps the audio stream and drops the video stream; MP3 and AAC are lossy, while WAV and FLAC are lossless. The default 192 kbps MP3 is transparent for most listening.
- You can export only a start-to-end segment in MP3, AAC, WAV or FLAC. MP3 and FLAC output can include title, artist and embedded cover art.
- Conversion runs locally in your browser—the source video and extracted audio are never uploaded.
- Select multiple videos to batch-extract full audio tracks. Each result can open in Audio Editor, or all results can go to Audio Merge or the Video Player.

Common Audio Extraction Uses
- Turn a video's audio track into a ringtone or alert sound
- Save podcasts and lectures for offline listening
- Extract a quote, sound effect, or song segment for editing
- Clip audio segments for remixes and creative projects
- Add a missing song title, artist and cover to extracted MP3 audio
Audio Extraction and Tag Limits
- This tool creates a separate audio file; it doesn’t mute or remove audio from the source video
- Videos without an audio track (silent videos) have nothing to extract
- Lossless formats like WAV and FLAC produce larger files
- Embedded cover art is currently written to MP3 and FLAC; other formats do not store artwork
- A few rare audio codecs may fail to decode
How to Choose an Audio Extractor
- vs. desktop FFmpeg: no command line — a visual interface instead
- vs. upload-based online tools: nothing is uploaded, so it's private and secure
- vs. a basic audio extractor: segment trimming, quality controls, title, artist and cover editing are included
How Audio Extraction and Tag Writing Work
- Extracting audio means dropping the video stream and keeping only the audio (FFmpeg's -vn). The output format decides whether it's re-encoded: converting to MP3 or AAC (different from the source) requires re-compression, while WAV keeps the complete sample data.
- The lossy/lossless divide: MP3 and AAC use psychoacoustic models to discard frequencies your ears barely notice, which is how they stay so small. WAV and FLAC keep every original sample — bigger, but lossless.
- A 192 kbps MP3 is "transparent" (indistinguishable from the source) for most listeners, and 320 kbps is the format's ceiling. For higher fidelity, switch to FLAC instead of pushing the bitrate.
Audio Extraction, Cover & Tag FAQ
Can I extract audio from a video without uploading it?
Yes. FFmpeg WASM reads the file in your browser, so the video stays on your device while the audio is exported.
How is this different from converting video to MP3?
This page can choose MP3, AAC, WAV, or FLAC; the dedicated Video-to-MP3 page is focused on the most common MP3 workflow.
How is the audio quality?
The default 192 kbps bitrate sounds clear. You can customize it — higher bitrates mean better quality and larger files.
Which videos can I extract audio from?
Common formats such as MP4, MKV, MOV, AVI and WebM work. For audio-only files, use Audio Converter or Audio Editor instead.
Can I extract only part of the audio?
Yes. Set start and end times to grab exactly the segment you want — handy for ringtones or a single quote.
Will the extracted file be smaller than the video?
It depends on the source track and output format: converting to a lower-bitrate MP3 is usually much smaller, while WAV/FLAC output may be larger.
How do I convert a video to MP3?
Upload the video, choose MP3 as the output format, and extract — no intermediate steps needed.
Can I add cover art and song info to extracted audio?
Yes. Enter the title and artist and upload a JPG, PNG or WebP image before extraction. MP3 and FLAC output store the cover as an embedded tag.
Does extracting audio preserve quality?
The default 192 kbps MP3 is transparent for most listening, but it is re-encoded. Choose WAV for uncompressed samples or FLAC for lossless compression when source quality matters.
Can I extract audio from multiple videos at once?
Yes. Select multiple videos to enter batch mode and extract the full audio from each. Download each result, send individual files to Audio Editor, or send all results to Audio Merge or the Video Player.
