Image ↔ Base64 Converter
Turning an image into a Base64 Data URL lets you inline it in HTML / CSS / JSON and save an HTTP request (good for small icons). This tool goes both ways: pick an image to get its Data URL (with size), or paste Base64 / a Data URL to preview the image.
Everything is encoded locally with the browser-native FileReader, never uploaded — images can contain screenshots, IDs and private info that shouldn't go into a tool that uploads. Note: Base64 inflates size by ~33%, so it's not worth it for large images.
