Why cut audio online?

Cut sections of podcasts, interviews, or WhatsApp audio by viewing the waveform — no need to install Audacity or any editor.

What if I need the text from this audio?

After cutting, you can transcribe the file with AI on VoxScriber: 30 free minutes per month, with automatic punctuation and speaker identification. Ideal for WhatsApp audios, meetings, and interviews.

Is Cut Audio Online Free really free?

Yes, free and unlimited. Processing happens in YOUR browser (WebAssembly), so we have no server cost — and you don't need to create an account.

Is my file uploaded to any server?

No. All processing is local (FFmpeg compiled to WebAssembly running on the page). The file never leaves your device — it even works offline after the page loads.

Is there a size or quantity limit?

The limit is 300 MB per file (browser memory). There is no limit on number of uses. For larger files, VoxScriber processes on the server with upload up to 5 GB.

Does it work on mobile?

Yes — any modern browser (Chrome, Safari, Firefox, Edge) on desktop or mobile. On older phones, large files may take longer.
