Audio Tools
Cut, trim, and convert your audio files
Audio files come in many formats — MP3, WAV, OGG, M4A, FLAC, and more — each with different trade-offs between quality, file size, and compatibility. Whether you are editing a podcast, creating a custom ringtone, preparing audio for a website, or converting between formats for a specific platform, our free audio tools handle the job entirely in your browser.
Our MP3 Cutter lets you trim audio to exact start and end points with sample-level precision, while the Audio Converter re-encodes between formats using the Web Audio API. Both tools process your files locally — no uploads to external servers, no waiting in a processing queue, and complete privacy for your audio content.
Browser-based audio processing has matured significantly with the Web Audio API, which provides professional-grade decoding and encoding capabilities directly in the browser. This means you get desktop-quality audio editing without installing any software, and your files remain completely private since they never leave your device.

Open toolFrequently Asked Questions
Are these audio tools free to use?⌄
Yes, both our MP3 Cutter and Audio Converter are completely free with no sign-up required. There are no usage limits, no watermarks added to your audio, and no hidden costs.
Do my audio files get uploaded to a server?⌄
No. All audio processing happens in your browser using the Web Audio API. Your audio files are decoded, processed, and re-encoded locally — they are never transmitted to or stored on any server.
What audio formats are supported?⌄
The tools support MP3, WAV, OGG, M4A, AAC, and FLAC for input. The MP3 Cutter outputs WAV format, and the Audio Converter can output WAV, MP3, or OGG depending on your browser's encoding capabilities.
Will I lose audio quality during processing?⌄
Cutting audio does not recompress the content — it extracts the exact samples you selected. Format conversion does involve re-encoding, which may introduce quality loss depending on the target format and bitrate settings. Converting to WAV preserves the current quality since WAV is uncompressed.
