Image tools that never upload your files

What happens when you use a tool

You pick an image straight from your device. The page hands those bytes to a Web Worker — a background thread inside the tab — which does the decoding, resizing and re-encoding there. When it finishes, your browser saves the result back to your device. Nothing is uploaded, nothing is queued, and closing the tab ends the whole thing.

That means no sign-up, no file size limit imposed by a server, and no copies of your images sitting on someone else's disk. It also means the tools work offline once the page has loaded, and that a slow connection only affects how fast the page arrives — never how fast your images are processed.
