How exact-KB compression works
This adjusts JPG/WEBP quality and, if needed, slightly reduces pixel dimensions until the file lands just under your target — typically with a small safety margin so a strict portal doesn't reject it for being a byte over. The compression runs on a background thread when your browser supports it, so the page stays responsive even on a large photo. Your file is never sent to a server — everything happens on your device.
