Public compression example: reproduce artifacts with safe pixels

To ask about Image Compressor artifacts publicly, create or choose a harmless image with the same challenging detail: a gradient, fine lines, small text, or transparent edges. Share original and compressed versions with dimensions, formats, sizes, and settings. Check metadata and remove private visual content first. A tiny blurred screenshot without the source cannot show whether the loss came from compression, resizing, or the viewer. A controlled pair makes diagnosis possible.
