Basic costs $6 for two months with 500 pictures per month; Standard costs $12 for six months with 1,000 per month; Premium costs $22 for twelve months with 2,000 per month. All three paid packages allow up to 16x enlargement and 50MB files, with priority processing, parallel jobs and batch mode. Package duration and monthly image allowance are separate. Offline processing is available with an account, including Free. If you submit without logging in, keep the browser open while processing.

The interface includes a Theme Initialization Script that automatically manages the color scheme based on user preference or system settings, helping create a consistent browsing experience across sessions. When the theme is set to system, ChatGPT switches between light and dark modes to match the device’s preferences. When set to light or dark, it retains that choice across page reloads for a personalized, predictable experience. This theme behavior improves readability, reduces eye strain, and supports a more comfortable, intuitive user experience on the ChatGPT platform. |
