A professional utility for developers to quickly encode and decode Base64 strings. Paste your text or data below to begin.
What is Base64?
Base64 is an encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.
It is commonly used to encode data (like images or documents) so it can be safely transmitted over networks that are designed to handle only text, preventing data corruption during transfer.
