Choose a Tool

Six focused tools that do one job well. Everything runs on your device, so there is nothing to upload and nothing to wait for.

Simple by design

How It Works

Three steps, no account, and nothing to install.

  1. 1

    Upload your file

    Drag and drop an MP3, WAV, OGG, FLAC, AAC or M4A file — or browse for it. It is read straight into your browser's memory, never sent anywhere.

  2. 2

    Choose your settings

    Trim with a waveform, pick a target format, set the speed, or boost the volume. Every control updates instantly with a live preview.

  3. 3

    Download the result

    Press process and watch the progress bar. When it finishes, your new file downloads directly — with no watermark and no signup.

Nothing is uploaded

AudioKit has no file server. Your audio is read into browser memory, processed there, and released when you close the tab.

Your device does the work

Processing runs in WebAssembly at native speed on your own CPU, so results arrive faster and the site never gets congested.

Works offline

Once the page has loaded, you can disconnect from the internet and the tools keep working. That is the clearest proof nothing is being sent.

Buy the dev a coffee

There are no ads, no accounts, and no uploads to pay for. If these tools saved you time, you can chip in — it goes straight back into keeping them running.

Optional, and never required to use any tool

Pay by UPI

Bank to bank, with no platform taking a cut. Works from any UPI app.

FAQ

Frequently Asked Questions

Short answers to the things people ask most before they start.

No. AudioKit processes every file locally in your browser using WebAssembly. Your audio is never transmitted to a server, never stored, and never seen by anyone but you. You can even disconnect from the internet after the page loads and the tools keep working.
