Healthcare teams handle two very different kinds of image: clinical files that must never leave the device, and public-facing images — a clinic website hero, a team photo, a presentation slide — that are just ordinary marketing assets. Both arrive oversized. The safe default for the whole category is a tool that processes locally: if the compression never leaves the browser, you cannot accidentally upload something you should not have. For public images the usual rules apply: resize to how the image is actually displayed, then compress. A clinic website hero at 1920px does not need a 4000px source, and dropping the resolution is the single biggest saving. For internal documents, the target is the smallest file that still reads clearly on a screen.
