자주 묻는 질문

What is Base64 encoding?

Base64 converts binary data into ASCII text using 64 printable characters. It's used for embedding images in HTML/CSS, sending binary data in JSON/XML, email attachments (MIME), and data URLs.

Does Base64 increase file size?

Yes — Base64 encoding increases size by approximately 33%. A 100KB file becomes ~133KB when Base64 encoded. This is the tradeoff for text-safe transport.
