PNG is lossless, so big reductions usually mean converting — Auto mode picks the smallest format that keeps quality.
Portal limits change — double-check the current notification before you submit.
Quality is lowered only as far as the floor allows. If that still isn't enough, the image is scaled down in small steps instead — downscaling looks far better than heavy compression artifacts. EXIF metadata (location, camera, serial numbers) is always removed for your privacy; colour accuracy is kept.
Screenshots and graphics stay crisp as PNG; photographs saved as PNG are usually 5–10× larger than they need to be. Auto output converts photos to WebP or JPEG while keeping graphics sharp, and transparency is preserved when the output format supports it.
