- 03
Convert the audio locally, preview the result and download the new file.
Which audio formats can I convert?
The current converter accepts common formats that your browser can decode, including MP3, WAV, M4A, AAC, OGG, FLAC and WebM on compatible browsers. Output is MP3 or WAV.
MP3 or WAV: which should I choose?
MP3 creates much smaller files and is convenient for sharing and everyday listening. WAV is uncompressed PCM audio and is usually a better choice for editing, production and archiving intermediate files.
What do bitrate, sample rate and channels mean?
MP3 bitrate affects compressed file size and quality. Sample rate controls how many audio samples are stored per second. Stereo keeps two output channels while mono uses one. For music, 44.1 kHz stereo and 192–320 kbps MP3 are common choices.
Does ToolYogi upload my audio?
No. Audio decoding, resampling and encoding run locally in the browser. The MP3 encoder library is downloaded as a static resource, but your selected audio is not sent to ToolYogi for conversion.

Frequently asked questions
Is the Audio Converter free?
Yes. The current ToolYogi Audio Converter works without an account.
Can I convert M4A, FLAC or OGG to MP3?
If your browser can decode the source codec, yes. Browser codec support varies, so WAV and MP3 are the most broadly compatible inputs.
Can I convert MP3 to WAV?
Yes. Choose WAV as the output format and the browser will decode the MP3 and export PCM WAV.
Does conversion happen on a server?
No. Conversion runs on your device in the browser and ToolYogi does not create a cloud conversion history.
What MP3 bitrate should I use?
192 kbps is a practical default. Use 256 or 320 kbps when you prefer a larger file with less lossy compression.
Local browser conversion
WAV output is encoded directly by ToolYogi in the browser. MP3 export uses the open-source @breezystack/lamejs encoder. Your selected audio is not uploaded for conversion.
