flag-icons is a curated collection of country flags in SVG format with accompanying CSS for straightforward integration into web projects.
The project solves the problem of obtaining and displaying country flags consistently across applications. It provides all country flags as individual SVG files organized by ISO 3166-1-alpha-2 country codes, paired with pre-built CSS classes that handle the styling and layout. Developers can use flags inline with text by applying simple class names, or as background images on any HTML element. The tool supports both rectangular and squared flag variants and offers multiple integration methods including direct download, npm installation, or CDN delivery.
The collection suits projects that need reliable, standardized country flag imagery without building custom assets. It works well for applications displaying country selection dropdowns, location indicators, or international content. The project can be customized by removing unwanted countries from the build configuration before compilation, allowing developers to reduce file size if only a subset of flags is needed. The tool provides CSS, SASS, and CDN-based approaches, giving flexibility in how it integrates with different build pipelines and project structures.
Development activity shows consistent maintenance with regular updates to the flag collection and build tooling. The project accepts contributions and maintains clear documentation for both end users and developers who want to extend or modify it. Build infrastructure is straightforward, with simple commands for compilation and local development serving.
