The ClipTools MP3 Cutter lets you pick a start and end point on a slider and cut that exact section out of an audio file, then download it as an MP3. It accepts MP3, WAV, M4A, AAC, OGG, FLAC and OPUS files up to 500 MB, and outputs a clean MP3 re-encoded at high VBR quality (around 190 kbps). It is a trimmer, not an editor: it cuts the part you select without changing the speed or merging clips. There is no watermark, no signup, and no limit on how many files you cut.

Everything runs entirely inside your browser using ffmpeg compiled to WebAssembly (ffmpeg.wasm), so your audio is never uploaded to any server. The file is decoded and the selected segment is re-encoded locally on your own device, then handed back to you as an MP3 download. It is built for anyone making a ringtone, pulling a chorus out of a song, trimming dead air off a podcast, or grabbing a short sound clip without installing software.

Why use this tool

Your audio never leaves your device

Your audio is processed entirely on your own device through ffmpeg.wasm and is never uploaded to a server, so private recordings and unreleased tracks stay with you.

Wide format support, MP3 out

Load MP3, WAV, M4A, AAC, OGG, FLAC or OPUS and always get back a standard MP3 that plays on any phone, browser or media player.

Precise slider trimming

Drag the start and end handles to grab the exact section you want, with no rough guessing and no editing skills required.

High-quality output

The cut section is re-encoded at high VBR quality (around 190 kbps), keeping music and speech clear in a small, shareable file.

Frequently asked questions

Is this MP3 cutter free?
Yes, it is completely free with no signup, no watermark, and no limit on how many files you cut. Every part of the tool works without an account or payment.
Does my audio file get uploaded to a server?
No, your audio never leaves your device. The cut runs locally in your browser using ffmpeg compiled to WebAssembly, so the file is processed in memory on your own computer and nothing is uploaded, stored, or sent anywhere.
Which audio formats can I cut?
You can load MP3, WAV, M4A, AAC, OGG, FLAC and OPUS files. Whatever format you start with, the result is always saved as a standard MP3 that plays everywhere, so you do not need to convert the file first.
Is there a file size limit?
The input file can be up to 500 MB. Because the work happens in your browser, very large files use more of your device's memory and take a little longer, but anything within that limit is supported on a modern desktop browser.
How does the MP3 cutter work under the hood?
It uses ffmpeg compiled to WebAssembly (ffmpeg.wasm), running entirely inside your browser tab. When you confirm your start and end points, ffmpeg.wasm decodes the audio, keeps the selected segment, and re-encodes it to MP3 on your device.
Will cutting reduce the audio quality?
The selected section is re-encoded to MP3 at high VBR quality (around 190 kbps), which keeps the result clear for music, speech and sound effects. Because it is a re-encode rather than a raw copy, the output is a clean, widely compatible MP3 rather than a bit-for-bit duplicate of the original.
How fast is it?
Most clips are cut in a few seconds because the audio is processed directly on your device with no upload or download round-trip to a server. Longer source files and slower machines take a bit more time, but you never wait on a network connection.
Can I use it to make a ringtone?
Yes. Drag the slider to the part of the song you want, set the start and end points for the length you need, and cut it out as an MP3 that you can set as a ringtone or notification sound on your phone.
