Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that converts binary data into ASCII string format. It uses 64 different ASCII characters (A-Z, a-z, 0-9, +, /) to represent binary data.
Why use Base64 encoding?
Base64 is commonly used to encode binary data (like images or files) for transmission over text-based protocols like JSON, XML, or email. It ensures data integrity during transfer.
Is Base64 encryption?
No, Base64 is not encryption. It is merely an encoding format that can be easily decoded. Do not use it to hide sensitive data.
What happens to special characters?
Special characters and non-ASCII text are automatically handled. The encoder converts them to UTF-8 bytes first, then encodes the result in Base64.
