Frequently Asked Questions
What is Base64 encoding?
Base64 encodes binary data (like images) as ASCII text. This allows images to be embedded directly in HTML, CSS, or JavaScript.
When should I use Data URI?
Use Data URI when embedding images in HTML/CSS (e.g., background-image). Use raw Base64 when working with APIs or databases.
Does Base64 increase file size?
Yes, Base64 encoding increases size by ~33%. Best for small images like icons. For large images, use regular file hosting.
