Pro Tips
Best for Small Images
Base64 is ideal for small images (under 10KB). Larger images may slow page load as they can't be cached separately.
Use Data URI for HTML
Choose Data URI format when embedding in HTML img tags or CSS. It includes the MIME type needed by browsers.
Size Increases by 33%
Base64 encoding increases file size by about 33%. Consider this when embedding many or large images.
