Use this free online Base64 Encoder / Decoder to convert plain text into Base64 encoded text or decode Base64 encoded content back into readable text. Enter your text in the input area or upload a supported file for conversion. After processing, you can copy or download the converted text for later use.
Base64 is commonly used in web development, email systems, APIs, and data transmission. It allows binary data such as images, documents, and other files to be represented as plain text so they can be safely transferred across systems that are designed to handle textual content.
Understanding Base64 Encoder / Decoder
Base64 is an encoding scheme that converts binary or textual data into a set of 64 ASCII characters. The encoded form consists of letters, numbers, and a few additional symbols, making the data suitable for storage or transmission through text-based systems.
Decoding reverses this process by translating the Base64 representation back into its original form. Since Base64 is an encoding method rather than encryption, the original information can always be restored when decoded correctly.
