Base64 Encoder & Decoder
Securely encode and decode text strings or entire files using Base64 directly in your browser.
What is Base64?
Base64 is an encoding scheme used to represent binary data in an ASCII string format. It is commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text. This helps ensure that the data remains intact without modification during transport.
