When would I use Base64?
Embedding images in HTML/CSS, storing binary in JSON, encoding credentials, or sending binary data through text-only channels. Data URIs use Base64.
Does it increase size?
Yes, Base64 increases size by ~33%. 3 bytes become 4 characters. It's for compatibility, not compression.
