What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is widely used to embed image files or other binary data directly within HTML documents, CSS stylesheets, or JSON payloads without requiring separate requests.
Data URI format starts with 'data:[mime/type];base64,' followed by the encoded string. It allows web browsers to render images directly. Our tool runs completely in your browser, ensuring your files and private texts are processed safely and never sent to any external server.
