Ringtone

MP3 at 128 kbps · WAV as 16-bit PCM · encode stays local (LAME via lamejs).

How to verify no upload
  1. Open DevTools → Network.
  2. Drop an MP3 or WAV, trim, play, download MP3 or WAV.
  3. Confirm no POST of your audio bytes — only static assets load.

Decode uses Web Audio; MP3 encode uses a local LAME build (lamejs). No audio upload.

How it works

ClipAudio is a neon waveform studio: your file paints peaks across a deep-purple timeline. Drag magenta (in) and cyan (out) markers, preview the selection, then download trimmed MP3 or WAV. Everything stays in your tab.

Unlike cloud MP3 cutters that upload tracks to a server, ClipAudio never posts your audio for processing. Free forever — no account, no Pro, no ads. Open MP3 or WAV; download trimmed MP3 (128 kbps) or WAV.

FAQ

Does ClipAudio upload my audio?

No. Decode, waveform, playback, and MP3/WAV export run in your browser. We do not upload audio bytes for processing.

Can I export MP3?

Yes. Trim the selection, then tap Download MP3. WAV download is still available as a second button.

Do ringtone presets change the file?

15s and 30s presets set the out marker relative to the in marker (clamped to duration). Then download MP3 or WAV of that selection.

Is this free forever?

Yes. Free forever — no login, no paid plan, no ads.
