No. All resizing and compression happens inside your browser on your own device. Your photo and signature are never uploaded anywhere, so your documents remain 100% private.
Why does the CAT portal reject my photo?
Portals reject images when the dimensions or the file size (KB) do not match the notification, or the format is not JPEG. This tool fixes all three at once — exact pixels, exact KB range and JPEG output — so the upload is accepted.
