Is it safe?
Yes. The photo is opened and resized by your own browser. It is never uploaded to a server, so nobody else can see it, and it works even if you go offline after the page has loaded. Saving a new copy also removes hidden camera data (EXIF), such as the GPS location where the photo was taken.
