About EazyAudio
EazyAudio is a collection of free web tools for converting, compressing and cutting audio. What sets it apart is how it works — every file is processed inside your browser, never on a server.
Why we built it
Uploading personal audio — meeting recordings, phone calls, your own unreleased tracks — to an unknown website just to change its format is more common than it should be. Most online converters send your file to their servers, and you never know where it is stored or when it is deleted. Free tiers often pile on size caps, daily limits and long queues.
EazyAudio takes the opposite approach. Instead of sending your file to a server, it brings the processing engine to your browser. Your file exists only on your device from start to finish — we never receive, see, or store it. And with no upload, there are no size limits and no queues.
The technology
All audio processing runs FFmpeg — the standard open-source engine for audio and video used by broadcasters and streaming services worldwide — compiled to WebAssembly so it runs directly in your browser.
Everything is built on proven open source; the libraries and licenses are credited in each tool's footer.
How is it free?
Because no files are processed on servers, running costs stay very low, and the site is supported by the ads on its pages. That is why there is no sign-up, no payment, no usage limit and no watermark.
Who runs it?
EazyAudio is built and run by an independent developer in South Korea — the second service from the team behind the PDF toolset EazyTools. Bug reports and feature suggestions are always welcome.
