Frequently asked questions
Are my audio files uploaded?
No — these tools process audio locally in your browser using an in-page engine, so your files never leave your device.
What formats can I convert to?
MP3, WAV, and M4A (AAC). Trimming keeps the original format; merging and volume changes output MP3.
Do I need an account?
No — every audio tool is free and works instantly with no sign-up.
