Convert video to MP3, WAV, M4A or FLAC
Choose MP3 for everyday listening, M4A for compact files, or WAV and FLAC for editing and archiving. You can export your audio in 10 formats.

Best for: iPhone and Mac playback, compact audio files
WAV
UncompressedExtract audio from video as uncompressed WAV for use in an audio editor. Files are larger than MP3, and converting to WAV cannot restore detail missing from the source.
Best for: Audio editing, mixing and production
FLAC

Best for: Archiving recordings and keeping audio for future edits

Three simple steps
How to convert video to audio online
Use your desktop or mobile browser. There is no software to install.
- 01
Upload your video
Choose a video from your device or drag it into the upload area. MP4, MOV, MKV, AVI and WebM are supported, with a limit of 1GB per file.
- 02
Choose an audio format
Keep the default MP3 output or choose another format such as WAV or M4A. You can also adjust the audio quality and sample rate.
- 03
Convert and download
Click Convert to start extracting the audio. When it is ready, listen to the preview and download the audio file to your device.
Audio settings
Choose the right audio quality and sample rate
Start with the default settings. Adjust them when you need a smaller file or a specific format for your player or editor.
Bitrate
For lossy formats, a higher bitrate generally keeps more detail but creates a larger file. Try 128kbps for speech or 192kbps and above for music.
Preserve source quality
The default setting copies a compatible audio stream without re-encoding when possible. Otherwise, it converts at a high bitrate; lossy conversion can still change the sound.
Sample rate
Keep the source sample rate unless your workflow needs a specific value. Increasing it does not improve the original recording. 16000 Hz is an option for speech workflows.

Common questions
Video to audio converter FAQ
Is this online video to audio converter free?
Yes. You can convert video to audio on NowText for free without registering or signing in. Upload one video at a time, up to 1GB per file.
Which video formats can I convert to audio?
You can upload common video formats including MP4, MOV, MKV, AVI, WebM, FLV, WMV, 3GP and TS. The file must contain a readable audio track; support also depends on the codecs inside the video.
How do I convert a video to MP3?
Upload your video, leave MP3 selected and click Convert to MP3. When conversion finishes, preview the audio and download your MP3 file. You can also choose M4A, WAV, FLAC, AAC, OGG, OPUS, WMA, AC3 or AIFF.
What is the maximum video file size?
The limit is 1GB per video. If your file is larger, trim it or reduce the video resolution with a video editor before uploading it.
Can I extract audio from video without losing quality?
When the source audio codec is compatible with the selected output and settings, Preserve source quality can copy the audio without re-encoding. Converting to a lossy format such as MP3 involves re-encoding when the source uses a different codec. WAV, FLAC and AIFF avoid additional lossy compression, but cannot restore detail already lost in the recording.
How long does it take to convert MP4 to MP3?
The total time depends on the file size, your upload speed and the conversion settings. Longer recordings and files that need re-encoding take more time. Keep the page open while the tool uploads and processes your video.
How can I convert a video to audio on iPhone or Android?
Open this page in your mobile browser, choose a video from your device, then select an audio format and convert it. Use MP3 for broad playback support or M4A for compatible Apple devices. No app installation is needed.
Can I convert MOV to MP3 or extract WAV from MP4?
Yes. Upload the MOV or MP4 file and select MP3 or WAV as the output format. You can also choose M4A for compact AAC audio or FLAC for lossless compression.
Why did the audio extraction fail?
Check that the video plays correctly and contains sound. A video without an audio track cannot produce an audio file. If a codec is unsupported, try another output format or export the video again from your editor.
Can I remove background music and keep only the voice?
No. This converter extracts the complete audio track, including speech, music and other sounds. It does not separate voices from background audio.
How can I get help with a conversion?
Email support@nowtext.ai or submit feedback using the button below. Include the input format, output format and error message so we can investigate.
Can I convert a video link to audio?
This tool works with video files uploaded from your device. It does not convert a pasted URL to MP3 or download videos from websites. To extract audio, upload a video file you have permission to use.
Want the words from your video, too?
Upload a video or use a supported sharing link to transcribe speech with punctuation and timestamps.
