Frequently Asked Questions

What audio formats are supported for trimming?
The trimmer supports all formats natively decodable by your browser, including MP3, WAV, AAC, M4A, OGG, FLAC, and WebM audio files.
How do I create a ringtone for my iPhone or Android?
For Android, select a clip between 15 to 30 seconds, export as WAV, and place it in your Ringtones or Notifications folder. For iPhone, export as WAV, import into the Apple Music / iTunes app on Mac/PC or GarageBand on iOS, and convert to AAC/M4R.
Does trimming audio reduce audio quality?
No. The audio is decoded into 32-bit floating-point PCM channels inside browser memory, sliced accurately without lossy re-compression, and exported directly as clean, uncompressed 16-bit 44.1kHz/48kHz WAV audio.
Is there a file size limit?
Because all processing takes place in your local computer RAM, there are no artificial file limits. You can easily trim 10MB to 200MB+ audio files without waiting for network uploads.
