Convert text and files to Base64 or restore Base64 to original data.
Base64 is an encoding method that represents binary data in ASCII string format. It's used for email attachments, embedding images in HTML, storing complex data in XML or JSON, and more.
Base64 uses only 64 safe characters (A-Z, a-z, 0-9, +, /) to convert any binary data to text. This ensures data can be safely transmitted between various systems.
Let's examine how the phrase "Hello" is encoded in Base64:
01001000 01100101 01101100 01101100 01101111
010010 000110 010101 101100 011011 000110 111100
The Base64 encoding of "Hello" is "SGVsbG8="
Standard Base64 encoding uses + and / characters, which have special meanings in URLs and can cause problems. URL-safe Base64 replaces these characters:
This allows Base64 data to be safely used in URLs, filenames, API keys, etc.
