Base64 online encoding and decoding tool
Function Introduction
This tool provides efficient Base64 encoding and decoding services , support for string , text or binary data encryption and decryption of Base64 format . Whether it is development and debugging, data transfer, or to solve the problem of Chinese garbled code, can be easily dealt with. Core Functions
1. Base64 encoding： Convert common text or data to Base64 format to ensure compatibility and security.
2. Base64 decoding： Reduce encoded Base64 strings to their original content, support Chinese and other languages.
3. Instant Processing： Real-time display of results after input, no need to manually submit, easy to operate.
4. Data Security： All processing is done locally in the browser, no server storage, zero privacy leakage. Scenarios
• Developers: Quickly debugging APIs, coding and transferring data.
• Data Processing: Solve the problem of messy Chinese characters in emails or web pages.
• Security requirements: simple encryption or decryption of sensitive information. Usage
1. Encoding： Paste text or data in the input box, the tool automatically generates Base64 encoding results.
2. Decode： Enter a Base64 string and the tool will immediately display the decoded plaintext content.
3. Copy Result： Copy the processed content with one click and use it directly for subsequent operations. Technical Notes
Base64 encodes binary data using 64 ASCII characters (A-Z, a-z, 0-9, +, /) and the padding character "=", which is widely used for data transmission and storage. This tool is compatible with the RFC 4648 standard to ensure the accuracy of the conversion. No registration, permanently free of charge, instant experience of efficient encoding and decoding! & nbsp; Base64 will be the input string by byte cut, get each byte corresponding to the binary value (if less than 8 bits, the high complement 0), and then these binary values in series, and then according to a group of 6-bit cut (because 2 ^ 6 = 64), the last group of less than 6 bits, then the end of the complement 0. The binary value of each group will be converted to decimal, and then in the above-mentioned Each binary value is converted to decimal, and then in the above table to find the corresponding symbols and series is the result of Base64 encoding.
& nbsp; Base64 can be used for arbitrary data encoding of the underlying binary data, in order to apply to the transmission of ASCII characters can only be occasions. However, the most commonly used in the processing of text data transmission, such as in the MIME format e-mail, Base64 can be used to encode the contents of the mail to facilitate the transmission of different languages between computers and not messy code, pay attention to the transmission rather than display, such as the use of utf-8 encoding can be used to display the normal Chinese in Western European computers (with the corresponding font), but it may not be able to normal transmission of Chinese, the This is not a concern when converting to Base64.
Base64 encoding, if not specified, usually agreed that non-ASCII characters are encoded according to the UTF-8 character set.
