"Audio Cutter" is a free online tool that lets you easily trim and cut MP3, WAV, AAC, and audio from MP4/MOV videos directly in your browser. No cumbersome software installation or account registration is required. Whether you are on a PC, iPhone, or Android smartphone, you can cut audio with intuitive touch controls. We use "Local Processing" technology, meaning your files are processed entirely on your device and are never uploaded to a server. You can edit confidential meeting recordings or private voice memos with complete peace of mind.
Zero upload time. The waveform appears the moment you drag and drop your file, letting you start your "MP3 Cut" task immediately.
All editing happens locally within your browser. Your audio data is never sent to or saved on external servers.
No dedicated app needed. Simply access the site via Safari on iPhone or Chrome on Android to use it as a high-performance audio editing tool.
Traditionally, you had to install "MP3 Cutter Freeware" on your PC. With this tool, all you need is a browser like Chrome or Edge. It works on Windows, Mac, Linux, and Chromebooks. You no longer need to launch heavy editing software just to "cut a small clip" or "make a ringtone."
We support MP3 as well as high-quality WAV files, audio extraction from MP4/MOV videos, and major formats like M4A (AAC), FLAC, and OGG. You can also choose your preferred output format:
We designed it for simplicity so anyone can use it without confusion. Edit in just 3 steps:
Drag and drop the audio file you want to edit into the center area, or click to select a file. The waveform will be displayed instantly upon loading.
Move the "Yellow Handles" displayed over the waveform to specify the range you want to Keep. You can zoom in/out with the mouse wheel or slider for precise trimming down to 0.1 seconds. Press the play button to preview your selection.
Pro Tip: Check "Apply Fade In/Out" to automatically smooth the beginning and end of the clip. This prevents abrupt cuts and gives a professional finish.
Once satisfied, simply click the "Save & Download" button. The file will be instantly processed in your specified format (MP3/WAV) and saved to your device.
Yes, all features are completely free. There are no limits on usage and no watermarks.
If you save in "WAV" format, there is no re-compression, so there is zero quality loss (Lossless). If you save in "MP3" format, slight compression occurs due to the standard, but by selecting a high bitrate (256kbps-320kbps), you can save with virtually no audible degradation.
Yes, lengthy meeting recordings or radio files can be loaded. However, since performance depends on your device's memory (RAM), extremely large files (several GBs) may cause the browser to slow down.
Yes, the created files are perfect for ringtones.
For Android:
Save the MP3 file to your device, then go to Settings > Sound > Phone ringtone and select the file.
For iPhone (iOS):
Save the file to "Files". Note that to set a custom ringtone on iOS, you may need to use GarageBand
on your phone to export it as a ringtone, or sync via iTunes/Music app on a computer, as iOS
restricts direct MP3-to-Ringtone setting from the browser.
