About Sound Tools

Sound Tools is a collection of free browser-based audio tools for everyday editing, effects and creative experiments. You can trim a recording, adjust its volume, explore voice tools or make a beat without installing a separate app.

Sound Tools is independently developed by zf.

Made for quick audio tasks

Choose a tool for the task at hand, listen to the result and download it in an available format. Each tool explains its controls and limitations on its own page. Start with the audio trimmer, volume booster or beat maker, or browse all tools.

Processing on your device

Audio and text entered into the tools are processed in your browser. Some tools need to download software or model files before they can run, and capabilities depend on your browser and device. Optional analytics are only enabled if you allow them. See our privacy page for details about network requests and browser storage.

Choose the right tool

Tools have different file, duration and device limits. Read the instructions on the page before processing a long recording or downloading a large model. For voice tools, use only voices you have permission to use.
