Base64 Encoder and Decoder Online
Quickly encode and decode Base64 strings with full UTF-8 support (accents, non-Latin scripts and emoji), and convert files and images to Data URIs for embedding in HTML and CSS.
How does Base64 work and why use it?
Embedding small icons and SVGs directly in HTML/CSS via Data URIs removes extra HTTP requests, which can speed up page load and First Contentful Paint.
Base64 turns binary bytes into 64 safe ASCII characters, so files aren’t corrupted when sent over email (MIME) or in HTTP API headers. Note: Base64 is an encoding, not encryption.
