Audio Cutter / Ringtone Maker

Make a ringtone or short audio clip privately

A good ringtone, alert sound or shareable quote usually needs only a few seconds from a longer recording. This audio cutter lets you pick a start time and an end time, then saves that section as a fresh audio file. It works with common audio files and also accepts video files when the sound you want is inside a clip. Because the output drops the video track, you can quickly turn a concert recording, voice memo, interview, lecture or screen recording into a compact MP3, M4A or WAV download.

The workflow is built for privacy. Your file is not sent to a server and there is no account, upload queue or cloud copy. The browser loads ffmpeg.wasm, writes the selected file into a temporary in-memory file system and creates the trimmed result locally. When the download starts, the temporary input and output names are cleaned up from the engine.

Use fades for cleaner starts and endings

Short clips can sound abrupt when they begin in the middle of speech, music or background noise. Optional fade-in and fade-out controls smooth the edges without needing a full audio editor. A small value such as 0.3 or 0.5 seconds is often enough for a notification sound, while longer music clips may benefit from one or two seconds. If you do not need fades, leave both controls at zero and the tool will trim only the selected range.

Choosing MP3, M4A or WAV

MP3 is the default because it produces small files and plays on almost every device, making it a practical choice for ringtones and quick sharing. M4A uses AAC audio, which is efficient and common on phones and modern media apps. WAV creates larger uncompressed files, but it is useful when you plan to keep editing the clip or want to avoid another lossy generation. For best results, test the downloaded file on the device or app where you plan to use it before deleting the original source. The first cut may pause while the media engine downloads, but later cuts in the same tab can start faster.
