What audio formats are supported for trimming?

This tool supports MP3, WAV, OGG, M4A, AAC, FLAC, and most other audio formats that your browser can decode. The trimmed output is saved as WAV format for maximum compatibility.

How do I precisely select the section to trim?

Use the two slider handles to set the start and end points of your selection. You can also fine-tune by dragging the handles slowly for millisecond precision. The selection info panel shows you the exact time range and duration of the selected segment.

Does trimming affect audio quality?

No. Trimming simply extracts a portion of the original audio without re-encoding or compression. The output preserves the original sample rate, bit depth, and channel count. Audio quality remains identical to the original file.

Can I use this tool to make ringtones?

Absolutely! Upload your favorite song, trim a 30-45 second section, and download as WAV. Most smartphones support WAV as a ringtone format. For iPhones, you can then convert the WAV to M4R format.

Is my audio file uploaded to a server?

No. This tool runs entirely in your browser. Your audio file is processed locally using the Web Audio API and never leaves your device. No data is uploaded to any server.

What format is the trimmed output?

The trimmed audio is saved as WAV format, which is a lossless format that preserves full audio quality. WAV is compatible with virtually all devices and audio players. If you need a different format, use our audio format converter after trimming.
