Each page opens the same free editor with settings tuned for one job. You can change everything afterwards, and nothing is ever uploaded.
- MP3 cutterOpen an MP3, drag across the waveform to keep the part you want and download a new MP3. The file never leaves your device.
- WAV trimmerTrim a WAV recording and save it as a lossless WAV at the same sample rate. Ideal for samples, voice-overs and field recordings.
- M4A cutterCut M4A files — including iPhone Voice Memos and music downloads — and save them as M4A, MP3 or WAV.
- iPhone ringtone makerPick the best part of a song, fade it out and save it as an M4R ringtone or an M4A you can set straight from the Files app on iOS 26.
- Android ringtone makerTurn any song or sound into an Android ringtone. Choose the part, fade it, and save an MP3 that shows up by name in your ringtone list.
- Notification sound makerMake short, punchy text tones, notification sounds and alert sounds from any audio clip.
- Fade in / fade outAdd smooth fade ins and fade outs to songs, podcast music beds and ringtones, with live preview of the curve.
- Normalize & volume boosterMake a quiet recording, song or ringtone louder — safely. Normalize finds the loudest peak and raises everything until that peak sits just below 0 dBFS.
- Extract audio from videoOpen a video file, select the part of the soundtrack you want and save it as an audio file — great for ringtones from your own clips.
- Cut MP3 into partsSplit a long recording into many files in one go — chapters of an audiobook, songs from a live set, or 10-minute pieces of a lecture. Choose a part length, a number of parts, or exact cut points.
- Audio file size calculatorHow big an MP3, M4A or WAV will be for any length and bitrate.
On your device
- MP3 cutter for iPhoneTrim MP3s and voice memos right in Safari on your iPhone — no App Store app, no account. The cut file lands in the Files app, ready to share or set as a ringtone.
- MP3 cutter for AndroidCut MP3 files on a Samsung, Pixel or any other Android phone straight from Chrome. The trimmed file is saved to your Download folder and can be set as a ringtone in a few taps.
- MP3 cutter for MacQuickTime can trim, but it can’t save an MP3 or add a fade. This browser cutter does both on any Mac — drag a file in, cut it, and save MP3, WAV, M4A or an iPhone M4R.
- MP3 cutter for WindowsWindows can play an MP3 but has no built-in way to cut one. Open this page in Edge or Chrome, drop the file in, and save a trimmed MP3, WAV or iPhone M4R in seconds — no installer.
- MP3 cutter for ChromebookChromebooks don’t ship with an audio editor, and installing one through Linux is overkill for a single cut. This page runs in Chrome, reads the file straight from the Files app and saves the result to Downloads.
