the problem
Most online converters upload your file to a server first. That is a poor fit for private photos, customer exports and unreleased video captions.
what it does
converter runs on your device. It turns HEIC photos into JPG, WebP images into PNG, JSON into CSV and SRT subtitles into VTT. It can also compress images and show the result before and after.
how it’s built
Each conversion runs in the browser, with WebAssembly codecs in web workers. It works in English, Dutch and Arabic.
