Color Contrast Checker (WCAG) Cuando Usarlo
Abre Color Contrast Checker (WCAG) cuando necesites un chequeo rapido de contraste entre dos colores sin instalar una suite de accesibilidad ni subir archivos.
Cuando aplica
Validar la etiqueta de un boton contra su relleno antes de publicar CSS. Comparar texto del cuerpo con el fondo de la paleta de marca. Confirmar que un titulo grande sigue pasando AA con fondo suave. Mantener los HEX en este dispositivo porque el calculo corre en esta pestana.
Que esperar
Elige colores de primer plano y fondo; la ratio y los resultados AA / AAA se actualizan al cambiar. Usa la vista previa para leer texto normal y grande. Todo en el navegador - sin subida y sin cuenta. La ratio usa la formula de luminancia relativa del W3C (WCAG 2.1).

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
