Compress Image to 500 KB

500 KB is the standard limit for many email attachments and e-commerce product photos. This tool compresses any image to 500 KB or less by tuning JPEG quality and, if needed, reducing resolution. At 500 KB you get a noticeably sharper image than at 200 KB — closer to 2000×1400 pixels at high quality. Perfect for sellers on eBay or Etsy who need to keep image detail while staying under upload caps.
