Image to Base64 Converter Guide
Image to Base64 converts an uploaded image into plain Base64 text and a ready-to-use data URL. This is useful for developers who need to embed small icons, test API payloads, or generate HTML and CSS examples without uploading files to a server.
For production websites, use Base64 mainly for small assets. Large images usually perform better as compressed files because browsers can cache them separately.
