How to trim an MP3

  1. 01

    Drop your MP3 onto the waveform

    The file is read locally in your browser and never uploaded.

  2. 02

    Drag the start and end handles

    Move them until the selection is exactly the part you want to keep. Zoom in for precise edges.

  3. 03

    Download the trimmed MP3

    One click exports the clip. Pro can keep the original bitrate instead of re-encoding.

Trim an MP3 without re-encoding

An MP3 is a chain of self-contained frames, so a trim can be a copy: the frames inside your selection are written out unchanged. That means no generation loss, no waiting for a conversion, and the tags and bitrate come along. Free exports keep the source format (an MP3 in, an MP3 out); Pro adds re-encoding to MP3, AAC or Opus when you want a smaller file.

MP3 trimmer vs MP3 cutter vs MP3 splitter

Three words for three different jobs. A trimmer keeps one part of a file and discards the rest. A cutter removes a section and keeps everything around it. A splitter turns one file into many tracks. They are the three most confused searches in this category, and all three run on the same engine here.

MP3 trimmer for ringtones, podcasts and voice memos

Take 30 seconds out of a song for a ringtone, cut the intro waffle off a podcast episode, shorten a voice memo to the part you will actually send, or pull a single answer out of an interview. Each of those is a two-handle job, which is exactly what this page gives you.

Trim an MP3 on any device

Windows, macOS, Linux, ChromeOS, Android and iOS all run the same page, because the work happens in the browser. There is nothing to install, nothing to update and no version to match your operating system.

Questions

Is this MP3 trimmer free?
Yes. Trimming, unlimited clips and unlimited exports in the original format are free - no account, no watermark, no ads. Pro is a one-time $19.90 purchase that adds batch ZIP export, CUE / chapters export and re-encoding to MP3, AAC or Opus.
Do I have to upload my MP3?
No. The file is read locally with the Web Audio API; the audio never leaves your device.
Does trimming an MP3 lose quality?
No. The audio frames are copied, not re-encoded, so the clip keeps the original bitrate and the original tags.
How long can the MP3 be?
There is no fixed limit - MP3 is cut on frame boundaries without being decoded as a whole. A two-hour recording trims as fast as a three-minute song.
Can I trim more than one part at once?
Yes. Add extra handle pairs and every selection is exported together in one pass.
What is the difference between MP3 trimmer and MP3 splitter?
A trimmer keeps one part of the file. A splitter cuts one file into many separate tracks. Use the splitter for chapters and DJ sets; use this page when you just want one section.
Can I trim an MP3 on my phone?
Yes, it runs in any modern mobile browser. For precise handle placement, a larger screen is easier.
