ImgExpand vs Uncrop

ImgExpand is a web-based AI tool that expands image backgrounds while keeping the main subject intact. It accepts JPG, PNG, and WebP images. Before generation, users can select the original frame or a custom ratio and reposition the photo by dragging it. The listed common ratios are 1:1, 3:4, 4:5, 9:16, and 16:9, with custom ratios also available. The site describes Expand Pro as providing higher consistency, larger canvas growth, and cleaner edge continuity than the standard Expand model. The maker presents the tool for photography, e-commerce product photos, print, social media, real estate, and design or advertising graphics. The Free plan costs nothing and gives 3 credits per day for Expand, a slow queue, and no watermark. A subscription costs $39.90 a month and includes 2,800 credits per month, Expand Pro access, and a priority queue; credits reset each month. A one-time payment costs $99 as a one-time purchase and provides 4,000 credits that never expire. The terms allow personal or commercial use subject to applicable law and third-party terms.

Uncrop is a free web tool for extending photos into layouts used by Instagram. It offers portrait (4:5), square (1:1), landscape (1.91:1), and Story/Reel (9:16) formats. Local expansion methods include edge pixel extrusion, symmetric reflection, ambient blur, and smooth smear. You can also choose blur, solid-color, gradient, or mirror-reflection backgrounds. Uploads support JPG, JPEG, PNG, WEBP, and HEIC. Uncrop says processing occurs in your browser, without sending photos to a server, and that photos and traces disappear when the tab closes or refreshes. Original content is not compressed or downsized, while downloads keep the upload format at the highest quality setting. There is no stated file-size limit, although files above 50MB may process more slowly in-browser. The responsive site works on modern smartphones and listed browsers, and processing can work offline after loading. All features are free without an account; advertising supports the plan. Gemini AI outpainting requires a paid Gemini API key.
