What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents 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 textual data. This ensures that the data remains intact without modification during transport.
Common Uses for Developers
Developers frequently use Base64 encoding to embed image data directly into CSS or HTML (Data URIs), encode Basic Authentication headers for API requests, or safely transmit complex payloads over JSON. This tool allows you to encode and decode these strings instantly and securely on your own device.
