Encode & Decode images Using base64
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's used to transmit and store binary data, like images or files, in environments that primarily handle text, such as email or web pages. This encoding ensures that binary data is safely transported over channels that may not reliably handle binary formats.
Here's a more detailed explanation:
Binary to Text:
Base64 converts binary data (sequences of bits) into a string of printable ASCII characters.
Why use it?
Some systems, like older email protocols, can only handle text-based data. Base64 encoding allows you to send binary data, like images or documents, through these systems by converting them into a text-based format.
How it works:
Base64 groups binary data into chunks of 6 bits, each representing a single character from a 64-character set (hence the name "Base64").
Common Uses:
Embedding images in HTML and CSS.
Sending email attachments.
Transmitting binary data over protocols that only support text.
Storing data in systems that require text-based input.
Size Increase:
Base64 encoding adds some overhead. The encoded string will be larger than the original binary data, typically by about 33%.
Not Encryption:
Base64 is an encoding scheme, not an encryption method. It can be easily decoded to reveal the original binary data.
