Frequently asked questions
What is Base64?
Base64 encodes binary data as text. A data URI like data:image/png;base64,... lets you embed images directly in HTML or CSS without a separate file.
When should I use this?
For small images (icons, logos) in HTML/CSS to reduce HTTP requests. Not recommended for large images - they're ~33% larger as Base64.
