Frequently asked questions

What is Base64?

Base64 is a way to encode binary data (like images) as plain text. It lets you embed images directly in HTML, CSS, or JSON without separate file requests.

When should I use Base64 images?

For small icons, logos, or critical above-the-fold images where avoiding an extra HTTP request is important. For larger images, use regular image files — Base64 strings are 33% larger than the binary equivalent.

Is Base64 the same as data URI?

Almost. A data URI includes the MIME type prefix: `data:image/png;base64,iVBORw0K...`. Plain Base64 is just the encoded string. Data URIs work in HTML and CSS; plain Base64 is used in some APIs and JSON.
