Start with the downloaded image
Use the downloaded image instead of a screenshot of the conversation. A screenshot may include interface elements and scale the image down before you start. You do not need to share your conversation, account or prompts with this tool.
Choose a mode for the picture
Use Basic for a first pass on a generated photograph or textured image. Anime is designed for illustrations with defined lines and flat colors. Compare the result at full size before choosing it for a final design.
Upscaling increases pixel dimensions and estimates detail. It does not reliably repair misspelled words, extra fingers or objects that were generated incorrectly. Correct those in the source image before enlarging it.
Prepare it for a layout or print
Choose 2× when a modest increase is enough, or 4× for a smaller source. Very large inputs can be reduced to meet processing limits, so check the downloaded dimensions. The original aspect ratio is preserved.
For print, calculate the pixels needed for the paper size and intended PPI first. A 4K landscape frame is 3840 × 2160 pixels; a square image needs cropping or borders to use that frame. This service is independent of OpenAI and does not connect to your ChatGPT account.
Frequently asked questions
Do I need to connect my ChatGPT account?
No. Download the image yourself and select the file here. This tool does not read your chats or prompts.
Will upscaling fix text or change the composition?
It preserves the image layout while estimating detail. It can alter small features, and it is not a reliable way to correct generated text or anatomy.
Is this an official OpenAI tool?
No. Images Upscale is an independent service. ChatGPT is a name used to describe where your source image came from.
