Text to Base64
Our Text to Base64 encoder is a simple online tool that converts entered text into a Base64-encoded string. Enter or paste the text you wish to encode into the field at the top of the page and click “Convert to Base64.”
Base64 Encoding
Base64 is a binary-to-text encoding scheme that transforms binary data into a text format using ASCII characters. The encoding utilizes a set of 64 characters, forming the "base 64" numeral system. This set includes uppercase and lowercase letters (A-Z, a-z), numbers (0-9), and two additional characters, '+' and '/' (as specified in RFC 4648):
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/ (pad: =)
Each character in the set represents a 6-bit value. Therefore, three 8-bit bytes of the input data are represented by four 6-bit Base64 digits (each occupying one byte in the output string). As a result, the encoded string is approximately 33% larger than the original.
The Base64 is commonly used to encode binary data for transmission across systems that may not reliably handle binary data. Encoding ensures that the data remains intact during transport. Common applications of Base64 include:
- Data Transmission in Emails;
- Storing complex data in XML;
- Encoding binary data in web pages with data URI;
- API authentication.
