Frequently asked questions
Which formats are supported?
Input: MP3, WAV, M4A/AAC, OGG, FLAC. Output: WAV (lossless) or MP3, so the result plays everywhere.
Why add a fade?
Hard cuts click and pop at the boundaries. A short 0.5–1 second fade makes the clip start and end smoothly — essential for ringtones and loops.
Is my audio uploaded?
No. Trimming runs in your browser with a WebAssembly audio engine — the file never leaves your device, only the engine downloads once from a public CDN.
