What MP3 Cutter does
A ringtone that starts exactly on the right lyric. A voice message without the ten seconds of throat-clearing at the front. A podcast snippet for social media. In every one of these cases you really want just one thing: to set a clean start and a clean end and cut away the rest. That is exactly what the MP3 Cutter is built for - no more, no less.
The moment you drop a file in, it is decoded right in your browser and drawn as a waveform. That waveform is not just decoration: the loud and quiet passages show you at a glance where a section begins and where it ends. You set the start and end time through two input fields, and the coloured selection in the graph updates live to show what you keep. The chosen duration is always shown so you know how long your cut will be.
The cut itself runs server-side with a real audio tool - no lossy re-encoding by the browser, just a precise trim. The result keeps the format of your source file. Before downloading you can play it back in the built-in player and compare the file size to the original. Happy with it? Download it, or file it in your Aktenschrank archive with a single click.
The common audio formats are supported up to a file size of 100 MB. That covers a full podcast, a long interview, or an entire DJ mix. The interface is deliberately minimal: file in, two times set, cut. Anyone who has ever opened a Swiss-army-knife audio editor with 400 menu items just to trim ten seconds will appreciate the focus.
Start and end can be set to within 0.1 seconds. That is fine enough for a clean beat cut and still simple enough to manage without a manual. The preview function plays exactly the marked range, so you never have to guess whether you are half a second too early or too late.
The MP3 Cutter belongs to the audio and video family at werkzeu.ge and works hand in hand with the other media tools. If you then want to stitch several snippets together, level out the volume, or convert the file to another format, the right tool is a click away. Everything runs in the same browser without your files touring a dozen third-party services.
