When to Use Base64 Images
- Small icons & logos — Inline in CSS to eliminate HTTP requests for tiny images.
- Email templates — Some email clients block externally hosted images; Base64 ensures they always load.
- Single-file apps — Bundle all assets in one HTML file for portable demos.
- API payloads — Send images as JSON strings when binary uploads are not supported.
When not to use: Large images significantly bloat HTML/CSS file size and prevent browser caching of images.
