Frequently Asked Questions
Does my audio file get uploaded to a server?
Never. The MP3 cutter runs entirely in your browser using the Web Audio API. Your audio file is processed locally on your device and never sent to any server.
Which audio formats does the MP3 cutter support?
The tool supports all common audio formats your browser can decode: MP3, WAV, M4A, AAC, OGG, and FLAC. Most modern browsers support all of these natively.
How do I set the exact cut points?
You can drag the purple start handle and indigo end handle on the waveform visualization, or type exact times directly into the start/end time input fields (format: mm:ss.ms). Both methods are synchronized in real-time.
What format is the exported audio?
The exported file is a high-quality WAV file, lossless and universally compatible. WAV preserves every detail of your original recording with no re-encoding artifacts.
