What is Base64 Image Encoding?
📋 Embed in HTML/CSS
Use Base64 encoded images directly in img tags or CSS without a separate file request.
📦 JSON/API Transport
Embed images inside JSON payloads when sending data to APIs that accept Base64 encoded image data.
📏 Size Increase
Base64 encoding increases file size by approximately 33%. For large images, use a URL reference instead.
🔒 100% Private
All encoding and decoding happens locally in your browser. Nothing is sent to any server.
