Uncrop

What Uncrop is

Uncrop is a free web tool for extending photos to fit Instagram layouts. It supports portrait (4:5), square (1:1), landscape (1.91:1), and Story/Reel (9:16) formats. For local expansion, it offers edge pixel extrusion, symmetric reflection, ambient blur, and smooth smear. Background options include blur, solid colors, gradients, and mirror reflections. Uploads can be JPG, JPEG, PNG, WEBP, or HEIC. Uncrop says image processing happens in the browser, photos are not sent to a server or stored, and traces are removed when the tab is closed or refreshed. It says the original content is not compressed or downsized, and downloads retain the upload format at the highest quality setting. There is no set file-size limit, although files over 50MB may take longer to process in the browser. The responsive tool works on modern smartphones and lists Chrome, Safari, Firefox, Edge, and Samsung Internet. Processing and downloading can work offline once the page has loaded. The Free plan includes all features, needs no account or sign-up, and is supported by non-intrusive advertising. Gemini AI generative outpainting requires a paid Gemini API key.
