Hello World
Use Base64 encoding when working with HTTP Basic Auth headers, embedding small assets, inspecting encoded payloads or exchanging text safely through systems that expect ASCII-safe content.
Base64 encoding is a method used to convert binary data into ASCII text. It is commonly used in web development to safely transmit data through systems that only support text.
Developers often use Base64 when working with APIs, authentication headers, email attachments and data URLs. It ensures that data remains intact without being corrupted during transfer.
This tool allows you to quickly encode and decode Base64 strings directly in your browser without sending data to any server.
Is Base64 the same as encryption?
No. Base64 only encodes data into text form. It does not protect or hide sensitive information.
Can I decode Base64 generated somewhere else?
Yes. Paste the encoded string and use Decode to convert it back to readable text.
