Image to Base64 Converter

It converts an image file into a Base64-encoded text string (data URI) that can be directly embedded in HTML, CSS, or JSON without an external file.

Upload or drag-and-drop your image. The tool instantly generates the Base64 string and data URI. Copy the result for your code.

The conversion uses the browser's FileReader API. Your image never leaves your device.
