Understanding Base64: How to Embed Images and Data Inline

What is Base64?

Base64 is a way to represent binary data (like images or PDF files) as plain ASCII text. This allows you to embed files directly into HTML, CSS, or JSON documents.

Performance: Data URIs vs. HTTP Requests

Every image on a webpage usually requires a separate HTTP request. This adds latency. By converting small icons or logos to Base64 (Data URIs), you embed them directly into the document, eliminating that network round-trip.

Tools for Conversion

• Text: Use the Base64 Converter for encoding strings and credentials.
• Images: The Image to Base64 tool converts files into ready-to-paste data:image/png;base64... strings.
• SVGs: Optimize vectors with SVG to Data URI for the smallest possible footprint.
