Q: What is Base64 image encoding?

Base64 encoding converts binary image data into an ASCII text string format. This allows you to embed images directly into HTML, CSS, or JSON files without making extra HTTP image requests.

Q: How do I use Base64 images in HTML or CSS?

In HTML, paste the Data URI into an image tag: <img src="data:image/png;base64,...">. In CSS, use it inside a url string: background-image: url("data:image/png;base64,...");.

Q: Does converting an image to Base64 increase file size?

Yes, Base64 strings are typically around 33% larger in string length than raw binary image files due to 6-bit encoding representation.
