What is Base64?
Base64 is an encoding scheme that converts binary data or text into a string of safe ASCII characters for transport over the internet. It is widely used in emails, API payloads, and embedding images in HTML and CSS. The Adawix Base64 tool lets you encode and decode text instantly without installing any software.
Base64 encoding increases data size by about 33%, so it is best used only when data must travel through text-only channels. The tool supports Arabic, English and any Unicode text. Completely free and works offline in your browser. For more productivity, also try: Hash Generator, JSON Formatter, or URL Shortener.
