Upload any image file and get a Base64 Data URL output that can be embedded into HTML, CSS, JSON payloads, or quick prototypes.
Data URLs combine MIME type and Base64 payload into a single string, such as data:image/png;base64,.... They are useful for inline assets in prototypes, emails, and small single-file demos. This tool reads your file with the browser FileReader API and converts it locally without uploading the image to a server.
