Base64 Image Encoder FAQ

Common questions about converting images to Base64 and deciding when Base64 is the right format for a project.

When should I use Base64 for an image?

Does Base64 make an image file smaller?

What is the difference between Base64 only and a data URI?

Can I use the output directly in CSS or HTML?

Why should large images usually stay as files instead of Base64?

Does the decoder work with plain Base64 text and full data URIs?
