Our verdict on Uncrop
Uncrop is a browser-based image expansion tool for creators who need to extend photo borders, change aspect ratios, or prepare images for social platforms. It accepts JPG, JPEG, PNG, WEBP, and HEIC files, and processes images locally in the browser without requiring an account, sign-up, or upload. The tool is particularly suited to users who want non-generative expansion methods and direct control over the resulting canvas.
Its standout feature is the range of local pixel-based expansion options. Edge pixel extrusion extends existing border details, while symmetric reflection, ambient blur, and smooth smear provide different ways to fill additional canvas area without generative output. Users can set custom canvas dimensions, choose aspect-ratio presets including Instagram formats, and adjust positioning, scale, blur, and darken controls. High-resolution PNG or JPEG export supports straightforward delivery after reframing.
The published Free plan includes all listed core features, has no watermarks, and is described as free forever with no paid tier. Gemini-powered generative outpainting is available as an optional workflow, but it requires the user's own paid Gemini API key, making that feature dependent on a separate service and credential. Uncrop is a strong fit for creators prioritizing local processing, manual control, and non-generative results. Users seeking automated integrations should look elsewhere because the product is web-only and does not provide API access.
