H2: What Is Base64 Encoding?
Base64 is a binary-to-text encoding scheme used to represent binary data in an ASCII string format. It is commonly used when data needs to be safely transmitted over systems that only support text.
Base64 encoding converts data into a set of 64 characters:
Uppercase letters (A–Z)
Lowercase letters (a–z)
Numbers (0–9)
Plus (+) and slash (/)
Equals sign (=) for padding
H2: What Is Base64 Decoding?
Base64 decoding is the reverse process of Base64 encoding. It transforms encoded Base64 strings back into their original readable text or binary data.
Decoding is essential when:
Reading API responses
Handling encoded credentials
Processing encoded files or tokens
Debugging applications
Our tool performs this process instantly and accurately.
