Free Design Tool: free color, CSS, image, PDF, and developer tools
Free Design Tool is a browser-based toolkit for designers and developers. Create harmonious color palettes, check WCAG contrast, generate gradients and shadows, convert images, optimize SVG files, work with PDFs, and export copy-ready CSS without installing software or creating an account.
Popular design tools
Use the color palette generator for brand colors, the contrast checker for accessible interfaces, the gradient generator for production CSS, the shadow and glassmorphism generators for visual depth, and the color format converter for HEX, RGB, and HSL values.
Browser-based utilities
Free Design Tool also includes image conversion and compression, favicon and QR code generation, JSON formatting, Base64 encoding, regular-expression testing, responsive CSS clamp values, grid templates, spacing scales, and local PDF workflows. Core tools process files in your browser whenever possible.
