What we built
BreezeConvert is a free online tool for converting images (PNG, JPG, WEBP, GIF, BMP) and audio files (MP3, WAV, OGG, AAC, FLAC, M4A) between formats. Unlike most online converters, BreezeConvert never uploads your files to a server. Image conversion runs entirely through your browser's built-in Canvas API, and audio conversion runs a WebAssembly build of FFmpeg — a widely used, open-source multimedia toolkit — directly inside the page. Everything happens on your own device.
Why we built it this way
Most "free" converters require you to upload a file to a remote server, wait for it to be processed, and then download the result — which means a copy of your file passes through (and is often temporarily stored on) someone else's infrastructure. We wanted a converter that respects that files can be personal: screenshots, unreleased audio, private photos. Doing the conversion locally, in the browser, removes that step entirely.
How we keep the lights on
BreezeConvert is supported by the advertising you see on this site. We don't sell your data — because we never receive it in the first place — and we don't charge for conversions. If you'd like to support the project, using it (and the occasional ad click, if something's genuinely relevant to you) is how it stays free.
