What Base64 encoding is used for
Base64 encoding is commonly used to represent text or binary data in a plain-text format that is easier to transmit through systems that expect text. You will often see it in APIs, tokens, embedded assets, and encoded payloads.
This tool helps you encode text to Base64 and decode Base64 back into readable text directly in your browser.
Encode or decode Base64
Use encode mode when you want to convert normal text into Base64. Use decode mode when you already have a Base64 string and want to turn it back into readable text.
