Free Online Base64 Encoder and Decoder
Base64 is an encoding scheme that converts binary data into ASCII text format. The Versatools Base64 tool makes it easy to encode any text to Base64 format or decode Base64 strings back to readable text, all in your browser without sending data to any server.
What is Base64 Used For?
Base64 encoding is widely used in web development and software engineering. Email systems use Base64 to encode attachments. HTML data URLs use Base64 to embed images directly in code. JWT tokens contain Base64-encoded headers and payloads. API authentication often uses Base64-encoded credentials. CSS can embed small images as Base64 strings to reduce HTTP requests.
Base64 vs Encryption
It is important to understand that Base64 is an encoding scheme, not encryption. Base64-encoded data can be decoded by anyone who knows it is Base64. Do not use Base64 to secure sensitive information. Use proper encryption algorithms for security purposes. Base64 is purely for data representation and transmission compatibility.
