Generate a ready-to-paste Base64 data URL from an image in seconds without installing anything.
Use Base64 strings in HTML, CSS, email signatures, prototypes, or quick development experiments.
Your file is encoded locally in the browser, so nothing is uploaded to our server.
Base64 turns binary image data into plain text so it can be embedded directly inside HTML, CSS, JSON, or email markup.
Base64 text is usually about 33% larger than the binary file because binary data is expanded into a text-safe format.
