Online tool for mutual conversion between Base64 encoding and hexadecimal
Base64 and Hex are two common data encoding methods primarily used to convert binary data into text format.
1、A method that uses 64 characters (A-Z, a-z, 0-9, +, /) to represent binary data
2、Every 3 bytes (24 bits) of data are converted into 4 Base64 characters
3、Commonly used for transmitting binary data in text protocols, such as email attachments, image embedding in HTML, etc.
4、Encoded data size increases by approximately 33%
5、Advantage: Can be safely transmitted in various text environments without character encoding restrictions
1、Uses 16 characters (0-9 and A-F) to represent data
2、Every 1 byte (8 bits) of data is converted into 2 hexadecimal characters
3、Commonly used to represent hash values, MAC addresses, color codes, etc.
4、Encoded data size increases by 100%
5、Advantage: Intuitive and readable, convenient for manual inspection and debugging
The main difference between them lies in encoding efficiency and application. Base64 is more compact and suitable for transmitting large amounts of binary data; Hex is more intuitive and suitable for scenarios requiring human reading. Both encoding methods are frequently used in web development, especially in handling file uploads, data encryption, and API communication scenarios.
