Text to Base64 Converter: Encode Text Online (Free Tool)

Base64 encoding is a method of converting binary data into an ASCII string format. This makes it possible to transmit binary data in text-based formats, such as email or XML. Our free online text-to-Base64 converter allows you to quickly and easily encode text into Base64. This guide explains what Base64 is, why it's used, and how our converter works.

What is Base64 Encoding?

Base64 encoding represents binary data in an ASCII string format by translating it into a base-64 representation. This means it uses 64 different characters (A-Z, a-z, 0-9, +, and /) to represent binary data. The "=" character is used for padding when the input data is not a multiple of 3 bytes.

Why is Base64 Encoding Used?

Base64 encoding is used in various situations:

• Email Attachments: Email systems are designed to handle text. Base64 encoding allows binary files (like images or documents) to be attached to emails by converting them into a text format.
• Data URIs: Base64 can be used to embed small files, like images, directly into HTML or CSS code as Data URIs, reducing the number of HTTP requests.
• Data Storage in Text-Based Formats: When storing binary data in text-based configuration files or databases, Base64 encoding can be used.
• Authentication: Basic HTTP authentication uses Base64 encoding to transmit usernames and passwords.

How Does Text to Base64 Conversion Work?

The process involves these steps:

1. Convert Text to Binary: The input text is first converted into its binary representation using a character encoding like UTF-8.
2. Divide into 6-Bit Groups: The binary data is then divided into groups of 6 bits.
3. Convert to Decimal: Each 6-bit group is converted into a decimal number between 0 and 63.
4. Lookup in Base64 Table: This decimal number is then used as an index into the Base64 character set (A-Z, a-z, 0-9, +, /) to find the corresponding Base64 character.
5. Padding: If the input binary data is not a multiple of 24 bits (3 bytes), padding characters ("=") are added to the end of the Base64 string.
