ThumbnailMaker is AI-powered software that creates YouTube thumbnails from text descriptions. Using Nano Banana Pro technology, it generates 1280×720 PNG thumbnails based on prompts and preset styles like Shocked Reaction, Before/After, or Tech/Review. Designed for creators, it requires no design skills or external tools. Users can generate multiple variations for comparison and edit thumbnails with text-based instructions. Standard resolution is 1280×720, with optional 4K export for higher quality. Operating on a credit-based system, costs are shown upfront, and thumbnails come watermark-free with full commercial rights. User data and images remain private, with options to delete stored content.
