Frequently Asked Questions
How can this website convert files without uploading them?
Modern browsers are incredibly powerful. We utilize FFmpeg compiled to WebAssembly (WASM), which allows us to run heavy video and audio conversion algorithms entirely within your device's memory.
Do you support converting other formats to MP3?
Yes! Any file that your web browser can decode can be converted. We support exporting to 34+ formats including MP3, WAV, M4A, AAC, WEBM, FLAC, OGG, ALAC and more.
Is my personal voice data analyzed or tracked?
No, never. We do not have database servers or tracking databases that store your audio files. All files are loaded locally, processed in your computer's temporary RAM, and discarded instantly when you close the tab.
