Question 1

What is Base64 encoding?

Accepted Answer

Base64 converts binary data like images into a text string, allowing them to be embedded in HTML, CSS, or JSON without a separate file.

Question 2

Data URL vs raw Base64?

Accepted Answer

A Data URL includes a prefix like data:image/png;base64, making it usable in HTML src. Raw Base64 is just the encoded string without prefix.

Question 3

Will Base64 increase my file size?
