What is Base64 for images?
Base64 lets you embed image bytes directly inside text formats like HTML, CSS, or JSON using a data URL. This can be convenient for small icons or single-file demos, but it increases file size and reduces cacheability.
When it’s a good idea
- Small icons in emails or prototypes
- Embedding an image in JSON for quick testing
- Single-file HTML demos
When to avoid it
- Large images (Base64 adds ~33% overhead)
- Web pages where browser caching matters
