Audio Format Converter - Frequently Asked Questions
Which audio formats can I convert between?
You can convert between MP3, WAV, OGG and M4A - the most common formats for music, voice notes, podcasts and video soundtracks.
Is my audio file uploaded to a server?
No. Conversion runs locally in your browser, so private recordings and meetings stay on your device.
Which format should I choose?
MP3 is best for sharing and general playback, WAV keeps studio quality for editing, OGG is an efficient open format, and M4A works well with Apple devices.
Does converting reduce audio quality?
Converting to a compressed format like MP3 or OGG can slightly reduce quality, while WAV stays lossless. For the best results convert from the highest quality source.
Is there a file size limit?
The limit depends on your device memory, as the file is processed on your device. Large files may take longer to convert.
