Design Tools

AIBox offers 38 free browser-based design tools built for designers, frontend developers, and anyone who works with visual assets. Our collection spans 7 categories — color tools, asset management, typography, layout builders, backgrounds, spacing calculators, and branding generators. Create color palettes with AI, build CSS gradients and box shadows visually, generate favicons, compress and resize images, preview Google Fonts, calculate type scales, build Flexbox and Grid layouts, and generate brand names and taglines with AI. Most tools run client-side using the Canvas API and modern browser features, so your images and design files are processed locally and never uploaded to a server. AI-powered tools like the Font Pair Suggester and Brand Name Generator leverage advanced language models for creative results. Whether you are prototyping a brand identity, building a design system, or optimizing assets for production, AIBox gives you essential design utilities without desktop software or SaaS subscriptions.
