Compress Image to 500KB Online Free
500KB is a generous ceiling — high-resolution photos usually reach it with almost no visible change, which makes it a good default when a form or CMS simply wants files kept reasonable.
This page presets the target to 500KB so you can compress a batch of camera images without configuring anything.
Your file never leaves your browser. All processing happens on your device. Nothing is uploaded to any server.
