Pixazo AI Image Extender vs Uncrop

Pixazo AI Image Extender uses outpainting to add generated content beyond a photo’s edges while keeping the uploaded subject the same size. In Pixazo AI Playground’s image-to-image editor, users choose Expand Image, create space around the image, generate an extension, review it, and can regenerate the result. It can make wider, taller, or square compositions, including 16:9 and 9:16 formats. The tool accepts one JPG or PNG image up to 5 MB and downloads the result as a PNG. Pixazo says it works in modern browsers without installation and is also available through an API. Suggested uses include reframing images, making room for text, expanding product shots, correcting tight crops, creating wallpapers, and extending AI art. Busy patterns, straight architecture, edge text or logos, extra faces or hands, and very large extensions can be difficult; it does not upscale resolution. Batch expansion is unavailable. Pixazo describes itself as an access layer for third-party image models it does not own. The Free plan is free and includes a 7-day trial with 100 bonus credits. Pro Monthly costs $15 a month, and Pro Yearly costs $120 a year.

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.
