What it does
Audio & Video Converter turns media you already have into a format you can share, edit, or open in another app. Drop an audio or video file, pick an output format, and download the result. Decoding and encoding run in your browser — files are not uploaded to our servers.
Audio outputs include MP3, WAV, FLAC, AAC, M4A, OGG, WEBM, and OPUS. Video-related options extract the soundtrack (when the browser can decode it) into a usable audio file such as MP3 or WAV-compatible containers. Use WAV when you need an uncompressed intermediate for further editing; use MP3 when you need a smaller file for chat or email.
What works best
WAV is lossless PCM and opens everywhere. MP3 is the most compatible compressed format for messaging and the web. WEBM / OPUS / OGG depend on browser MediaRecorder support and are ideal for web playback. If a specific codec is not available in your browser, the tool falls back to the closest working format and tells you in the status line.
Video files
When you upload a video, the converter works on the audio track. Frame-accurate video re-encoding is not the goal of this tool — for full video editing use a dedicated video editor. Here you get a clean audio export from MP4, WEBM, MOV, and similar containers your browser can decode.
How to use it
Upload media
Drop an audio or video file. Supported inputs are whatever your browser can decode (MP3, WAV, FLAC, M4A, MP4, WEBM, and more).
Pick an output format
Choose from the Audio list or a Video (audio extract) option depending on what you need next.
Convert
Click Convert. Encoding runs locally; larger files may take a few seconds on slower devices.
Download & use
Save the file, or send it into another local tool on this site for trim, normalize, or noise cleanup.
Tip: Prefer WAV when you will edit further; prefer MP3 when you only need to share. Preview before converting if you want to confirm the right clip is loaded.
Questions about Media Converter
01Can I export MP3?+
Yes. MP3 encoding runs in the browser. Choose MP3 from the Audio list and click Convert. For chat apps and email, 128–192 kbps quality is usually enough; the export uses a solid default bitrate for everyday sharing.
02What about video?+
Video uploads are supported. Choose a Video output (MP4, WEBM, MOV, MKV, AVI) to re-encode the file in your browser via ffmpeg.wasm, or pick an audio format to extract the soundtrack. First conversion may download the encoder engine (~25–30 MB, then cached).
03Is quality lost?+
WAV is lossless PCM from whatever the browser decoded. Lossy outputs (MP3, AAC, OPUS, and similar) discard some detail by design. Starting from an already-lossy file cannot restore studio-quality masters — convert from the best source you have.
04Is the file uploaded?+
No. Decoding and encoding stay on your device. Nothing is sent to our servers for conversion.
05What input formats are supported?+
Anything your browser’s decoder can read — typically MP3, WAV, OGG, FLAC, AAC/M4A, and the audio tracks of common video files such as MP4 and WEBM. Support varies slightly by browser and OS.
06Why did my format fall back to WAV or MP3?+
Some codecs depend on MediaRecorder support in your browser. If AAC, OPUS, or OGG is unavailable, the tool exports the closest working format (often WAV or MP3) and notes it in the status line so you still get a usable file.
