Frequently Asked Questions
Is Base64 a form of data encryption?
No. Base64 is strictly a data encoding method (binary-to-text representation), not encryption or hashing. Anyone intercepting a Base64 string can easily decode it.
Why does my Base64 string sometimes end with "="?
The "=" character acts as padding. It is added to the end of a Base64 string to ensure the final length is a multiple of 4, guaranteeing accurate decoding.
What is the difference with URL-Safe Base64?
Standard Base64 uses "+" and "/" characters, which can disrupt URL routing. URL-Safe Base64 replaces them with "-" and "_" respectively, allowing the string to be safely appended to web links.
