Frequently Asked Questions
Everything you need to know about processing files securely in your browser
How can I trim or cut an audio file online?
Drag and drop your audio file (MP3, WAV, M4A, OGG, or FLAC) into the dropzone. Use the range sliders or input precise start and end times in seconds, choose your preferred export format (MP3 or WAV) and bitrate, preview your selection, and click Trim & Download to export your file.
Which audio export formats and bitrates are supported?
You can download your cut audio as MP3 with selectable bitrates (128 kbps, 192 kbps, 256 kbps, 320 kbps, or 96 kbps) or as an uncompressed 16-bit PCM WAV file. You can also choose between Stereo or Mono output.
Which audio input formats does this tool support?
It supports most common audio formats, including MP3, WAV, M4A, AAC, OGG, and FLAC files up to 100MB in size.
Can I preview my edited audio before downloading?
Yes, you can click the Play/Pause buttons in the visual waveform player to hear exactly how your trimmed selection sounds before exporting.
Does the Audio Cutter reduce sound quality?
Selecting WAV guarantees 100% lossless PCM audio preserving master fidelity with zero quality degradation. Selecting MP3 at 192 kbps, 256 kbps, or 320 kbps delivers virtually indistinguishable high audio quality while reducing file size by 80% to 90%.
Is it safe to upload confidential voice or sound recordings?
Yes, because the files are never uploaded to any remote server. All audio decoding, editing, slicing, and MP3/WAV encoding happen 100% locally in your web browser via client-side Web Workers.
