About PixelTools

PixelTools is a set of free tools for everyday image jobs: making photos smaller, converting between formats, and resizing them for websites, social media and application forms.

Your images stay on your device

Most online image tools upload your files to their servers. PixelTools doesn't. The tools are built with WebAssembly versions of well-known open-source encoders — MozJPEG, libwebp, libavif and OxiPNG — that run directly in your browser. Your photos are decoded, processed and saved on your own computer or phone, and are never sent anywhere.

Why it's free

Because the work happens on your device, running the site costs very little. It is supported by unobtrusive advertising, which is always placed away from the tools themselves.
