Rennu

¿Qué es Rennu?

Rennu is a free tool for creating atmospheric, textured gradients inspired by Japanese art and design. Pick from curated presets or build your own from scratch — adjust colors, blur, texture, and direction until it feels right. No login, no watermark, no paywall. Export as PNG or JPG at any resolution — ready for backgrounds, wallpapers, UI screens, or brand assets. Built for designers who want that soft, textured, slightly imperfect look flat gradients just can't give you.
