![]() ![]() Storing data in XML or JSON files: Base64 is used to store binary data such as images or audio in XML or JSON files, as they do not support storing binary data directly.File uploads: Web applications use Base64 encoding to upload files to servers that only support text-based protocols.Mobile apps: Mobile apps may use Base64 encoding to store and transmit data, such as user credentials or settings.JSON web tokens: JSON web tokens use Base64 to encode and decode data in a compact and secure way.HTML and CSS: Base64 encoding is used in HTML and CSS to include images and other binary data directly in the markup.Encryption: Base64 encoding is sometimes used as part of encryption algorithms to encode and decode data.Password storage: Some applications use Base64 encoding to store passwords in a more secure way, as the encoded data is not easily readable by humans.Data transmission: Base64 encoding is commonly used for transmitting binary data over protocols that only support text, such as HTTP or SMTP.Email attachments: Email clients use Base64 encoding to send and receive email attachments, such as images or PDF files.List of Base64 Encode and Decode Applicationsīase64 encoding and decoding are used in a variety of applications for data encoding, transmission, and storage. ![]() Lowercase letters (indices 26-51): abcdefghijklmnopqrstuvwxyz.Uppercase letters (indices 0-25): ABCDEFGHIJKLMNOPQRSTUVWXYZ.It is important to note that the Base64 letters are case sensitive. Characters of the Base64 alphabet can be grouped into four groups. The Base64 Alphabet contains 64 basic ASCII characters which are used to encode data. It is also used in various programming languages for data serialization and other purposes.Įxample in plain text: Online Base64 Encode and Decode Toolīase64 encode data: T25saW5lV2ViVG9vbEtpdC5jb20gT25saW5lIEJhc2U2NCBFbmNvZGUgYW5kIERlY29kZSBUb29sCg= Base64 Characters It can also be used to encode passwords, digital signatures, and other types of data that need to be transmitted securely over the Internet.īase64 encoding does not provide any kind of encryption or security by itself, but it can be combined with other security measures such as SSL/TLS encryption to ensure the safe transmission of sensitive data. Most programming languages have built-in functions to encode and decode data using Base64.īase64 is often used to transmit data, such as images or documents, in a way that is safe and reliable. In practice, this size increase is rarely a source of concern.īase64 encoding is reversible, which means that the original binary data can be reconstructed from the encoded string. Hence the base64 equivalent of a binary file is about 33% larger. Each byte of base64 code contains 6 bits of data. To be precise, a base64 code is always a valid ASCII text and valid UTF-8. If the input data is not a multiple of three bytes, padding characters are added to the end of the encoded string.īase64 is just a standard text format that can be used to code any binary input. ![]() Each ASCII character represents six bits of the original binary data, resulting in a total of 24 bits or three bytes for every four characters. In Base64 encoding, every three bytes of binary data are represented as a string of four ASCII characters. The 64 characters include uppercase and lowercase letters, numbers, and two additional characters such as “+” and “/”. It uses a set of 64 characters, which are printable and well-supported by all computers and devices, to represent any binary data. What is Base64?īase64 is a binary-to-text encoding scheme that converts binary data into ASCII characters for transmission over the Internet. Direct copy and save/download your converted data to a file. Encode and Decode your text in Base64 vice versa. ![]()
