Cut audio online without uploading anything

This trimmer loads your file, draws its waveform, and lets you cut out exactly the section you want — all inside your browser. Because nothing is uploaded, it works instantly even on slow connections and your audio stays completely private. Select with draggable handles, preview the exact cut, and download a clean 320 kbps MP3.

What people trim audio for

The most common use is social content: a 15–30 second hook for TikTok or Reels, a Spotify Canvas clip, or a teaser for an upcoming release. Podcasters cut highlights for promotion, producers isolate sections to sample, and plenty of people just want a custom ringtone. Whatever the reason, the workflow is the same — find the moment, drag the handles, download.

Turn your best 30 seconds into a video

If you're cutting a hook to promote a song, consider what happens next: that clip needs visuals to perform on social. One More Shot AI turns your full track or trimmed clip into a beat-synced AI music video — pick a style, and the AI directs scenes, transitions, and effects to match the audio. The first video is free.

FAQ

Frequently asked questions

Everything you need to know about creating AI music videos.

How do I trim an audio file online?

Drop your file into the trimmer above, drag the start and end handles on the waveform (or type exact times), preview your selection, and hit Trim & Download. The cut happens locally in your browser — your audio is never uploaded to a server.

Does trimming reduce audio quality?

The trimmed section is re-encoded as a high-bitrate MP3 (320 kbps), which is perceptually lossless for almost all uses. The tool never touches loudness, EQ, or dynamics — you get the same audio, just shorter.

What audio formats does the trimmer support?

MP3, WAV, M4A/AAC, FLAC, and OGG all work. The output is always MP3, which plays everywhere.

Is there a file size or length limit?

No hard limit — since processing runs on your device, the practical limit is your browser’s memory. Full-length songs and podcast episodes work fine.

Why would I trim a track?

Common reasons: cutting a 15–60 second clip for TikTok, Reels, or a Spotify Canvas; making a ringtone; removing silence at the start or end of a recording; or isolating the hook of a song to use in a music video teaser.
