Frequently asked questions
Which MP3 bitrate should I choose?
Choose 128 kbps for a smaller speech file, 192 kbps for a general starting point or 320 kbps when file size is less important.
Is the converter free?
Yes. This tool uses local browser processing and does not call a paid conversion API.
Why does the first conversion take longer?
Your browser downloads the audio encoding engine on first use. The engine is served by this website; your audio stays local.
Which browsers and files are supported?
Use a recent Chrome, Edge, Firefox or Safari. Common MP3 and WAV files work best; other formats depend on browser and codec support. Source audio is limited to 50 MB in total, video to 150 MB / 6 minutes, and decoded audio to 32 million samples. Large files may exceed available device memory. The first MP3 export or video extraction downloads an approximately 32 MB processing engine.
