Impossible Images is an AI-powered stock image library and text-to-image generator. Users can browse a growing collection of thousands of unique AI-generated images, contributed by over 6,000 creators, for use in design projects, social media, and marketing materials. The built-in generator allows anyone to create custom images by entering a descriptive text prompt, choosing theme options, and generating results. Images can be downloaded directly, and upscaling to higher resolutions is available. Users can also sign up as contributors to sell their own AI-generated images, earning a 30% commission on sales. The platform includes a blog and community focused on prompt engineering. Commercial use is permitted under standard library terms, with restrictions on reselling images as standalone products. The service is free to start for generation and browsing, with paid credits for additional downloads and upscaling.
