What is Base64?

Base64 is a method of encoding binary data into ASCII characters to facilitate data transfer and storage.

What is ASCII?

ASCII stands for American Standard Code for Information Interchange. It is a character encoding standard that uses numeric codes to represent characters in computers and other devices that use text. ASCII assigns a unique number to each letter, digit, and punctuation mark on the keyboard, as well as other symbols and control characters.

In ASCII, each character is represented by a 7-bit binary number, allowing for a total of 128 different characters. The extended ASCII set uses 8 bits, allowing for 256 characters, which includes additional symbols and characters beyond the original 128.

ASCII is widely used in computers and communication devices to ensure that text can be shared and understood across systems. It does, however, have limitations when it comes to portraying characters from languages that use specific diacritical markings or characters that do not appear in the English alphabet. Unicode, which has a far broader character set, has largely displaced ASCII as the standard for worldwide text encoding.

What is Base64 Encoding?

In general, encoding is the process of transforming data from one format to another.

Base64 encoding is a binary-to-text encoding scheme that represents binary data in an ASCII string format by converting it into a set of 64 characters. It’s called Base64 because it uses a base of 64 to represent binary data. The encoding process involves breaking the binary data into chunks of 24 bits and converting each chunk into a set of four 6-bit values. These 6-bit values are then mapped to a set of 64 printable ASCII characters.

The Base64 character set includes:

Uppercase letters (A-Z)

Lowercase letters (a-z)
Numbers (0-9)
The plus sign (+)

The forward slash (/)

How Does Base64 Encoding Work?

Base64 encoding works on a simple principle: it divides binary data into 6-bit chunks and maps these chunks to ASCII characters. This produces a text-based representation that can be safely transmitted across multiple systems.

How are ASCII Characters Used?

ASCII characters represent text and control characters in computers. Each has a unique numeric code, enabling internal processing. They’re crucial for text representation, file storage, communication protocols, programming, command-line interfaces, character input, printing, display, and data transmission.

How Do I Use the Online ASCII to Base64 Encoder?

In the input field, enter the text you want to encode or upload a file.
Customise the settings, you can set each line to be encoded separately or the format of the output result.
No need to press a button, the Base64 result will automatically appear in the Output field.

If you want, you can copy the result using the Copy button.

How is ASCII Related to Base64 Encoding?

Base64 encoding uses a subset of ASCII characters (64 out of 128) to represent binary data. Uppercase and lowercase letters, digits, and a few other characters are included in this subset. Base64 encoding converts binary data to ASCII characters for simple transmission and storage while maintaining data integrity.

Is Base64 Encoding an Encryption?

Base64 encoding is a method of encoding, not encryption. Encryption transforms data in a way only specific individuals can reverse. Base64 is a reversible encoding scheme for representing binary data in a text format. It obscures data but does not offer security or confidentiality on its own.

Is it secure to use your ASCII to Base64 Converter?

Of course, yes, using our tool is safe, because we don’t save your data on our server, everything happens on the client side, on your computer. So feel free to use our tool, your information is safe.

Base64 Characters

Uppercase letters (A-Z), lowercase letters (a-z), digits (0-9), and two additional characters, typically “+” and “/”, comprise the set of 64 ASCII characters used in Base64 encoding. When the length of the binary data is not a multiple of three bytes, the “=” character is also used for padding.
