Audio tools — frequently asked questions
Is my audio private?
Yes. Conversion, trimming and compression run locally in your browser, so your files never leave your device. AI transcription is the exception — that audio is processed securely on the edge and never stored.
Which audio formats can I convert between?
Common formats including MP3, WAV, M4A/AAC, OGG and FLAC, so you can move audio between devices and apps freely.
Are the audio tools free?
Yes. In-browser audio tools are free and unlimited; AI transcription uses a few free credits per run.
