Choose the right audio format and quality for your needs
Use the audio converter when a track will not open in your player or editor, or when you need a smaller file that is easier to share. You can import MP3, WAV, FLAC, OGG, AAC, and M4A files and export them in the same or a different format.
Your selected files are not sent to an external server. The conversion engine reads the files and creates the results inside your current browser, so there is no upload queue and you download only the files you choose.
Choosing a format
Choose MP3 for broad compatibility and smaller files, or WAV and FLAC when you need edit-friendly, lossless audio.
Choosing a bitrate
128kbps suits speech and small files, 192kbps works well for everyday listening, and 256–320kbps prioritizes quality.
Batch conversion
Convert up to 10 files sequentially with one setting, then download results individually or together as a ZIP file.
Helpful answers before you start
Does converting WAV to MP3 change the sound quality?
MP3 reduces file size by discarding some audio data. A bitrate of 192kbps or higher works well for general listening, while WAV or FLAC is better if you plan to edit the audio again.
Which bitrate should I choose?
Start with 128kbps for spoken recordings and 192kbps for music or general video use. Choose 256kbps or 320kbps when quality matters more than file size.
Will converting MP3 to WAV restore the original quality?
No. Audio data already lost during MP3 compression cannot be restored by saving it as WAV. The conversion can still improve compatibility with editors that require WAV.
Can I convert several audio files at once?
You can select up to 10 files. They are processed one at a time to keep the browser responsive, with a combined size limit of 500MB.
Can I convert an audio file to the same format?
Yes. This can reduce bitrate or create a newly encoded file without source metadata. Avoid repeatedly re-encoding lossy formats such as MP3 or AAC because quality can decline.
Why can large files take a long time to convert?
Conversion uses your device's CPU and memory instead of a server. Closing other demanding apps and using a desktop browser can improve stability, and progress may occasionally appear to pause.
