Photo Extender
Photo Extender is a free online tool that uses AI outpainting to expand photos beyond their original edges. It is designed for users who need to fit an image into a different aspect ratio—such as converting a portrait photo to a square or wide format—without cropping the subject or stretching pixels. The service is powered by the gpt-image-2 model, which generates new background detail that matches the lighting, color, and texture near the edges of the original photo. The tool supports JPG, PNG, and WebP uploads up to 4MB and offers preset ratios including 1:1, 4:5, 16:9, 9:16, and 21:9, as well as fully custom ratios. Users can choose to extend from both sides or from the start/end of the image. Processing typically takes 60–120 seconds, and the result can be downloaded in full resolution. Photo Extender requires no sign-up, account, or subscription, and adds no watermark to output images. Uploads are sent over encrypted HTTPS to an AI processing partner. The tool is aimed at beginners and non-designers, with a simple three-step workflow: upload, choose ratio and direction, and download.

Problem solved
Photo Extender solves the problem of making a photo fit a required size or aspect ratio without losing important content. Instead of cropping into the subject or stretching the image, it uses generative AI to create new background areas around the original photo, producing a natural-looking expanded image ready for social media, print, or other layouts.
