How it works
Load your audio
Drop in an MP3 or any audio file. It decodes on your device and draws the full waveform.
Select and cut
Drag to select, then split, delete, or keep it — down to the sample. Chain cuts to build a ringtone.
Export any format
Save as MP3, WAV, FLAC, M4A, or OGG. Lossless sources stay lossless with FLAC or WAV.
Frequently asked questions
Is it really private?
Yes. Cutting, trimming, and exporting all run on your device with WebAssembly — your audio is never uploaded to a server. Close the tab and it's gone.
Can I cut multiple sections?
Yes. Split the track at any point, delete the parts you don't want, and reorder what's left. Make a ringtone from the chorus, drop dead air from the middle, or keep only a highlight — all on one timeline.
Will cutting lower the quality?
Cutting itself doesn't degrade audio. If your source is lossless and you export FLAC or WAV, it stays lossless. Exporting to MP3, M4A, or OGG re-encodes to a compressed format, which you can choose based on file size versus quality.
Is there a file size limit?
Because everything runs in your browser, files up to 512MB work comfortably. That covers full albums and long recordings without any upload wait.
Stitching tracks together instead? Use the audio joiner or drop long pauses with remove silence, all part of the full Audio Studio.
