Images are the leading cause of slow websites. Google's data shows that the majority of mobile pages have images that could be compressed further. Compressing before uploading is the single most impactful performance win you can make — and it costs nothing with ConvertPix.
ConvertPix uses the HTML5 Canvas API built into every modern browser to process your images entirely on your device. Your files are read from your local storage, processed in browser memory, and saved back to your downloads. They never travel over the internet — not even a single byte.
