The free tier lets you select a supported local file, use the same four presets and five controls, preview, and save without creating an account. Free export is 128kbps MP3 and is limited to at most 3 minutes per export. It is not a promise of a free full-length download for every input.
Use the main generator for the three-step workflow. If a file will not open, the online browser guide explains decode errors and how to try another supported local file.
Pro is needed for 320kbps MP3, WAV, or export without the free 3-minute duration cap. Previewing a longer file does not remove the download cap. Review the export notice before saving; a longer free result is cropped rather than exported in full.
For bitrate and format choices, read the MP3 export guide. Audio processing runs on your device, while loading the site, encoder, account features or ads may require a network connection. Local processing is not a guarantee that the whole website works offline.
