Frequently Asked Questions (3)
Q: What is Base64 encoding used for?
A: Base64 encoding converts binary data into ASCII text format, making it safe to transmit over text-based protocols like HTTP, email, and JSON APIs.
Q: Why does Base64 make data larger?
A: Base64 increases data size by about 33% because it uses 4 ASCII characters to represent every 3 bytes of original data, trading size for compatibility.
Q: Can I encode files with this tool?
