Frequently Asked Questions
What is a Data URI?
A Data URI embeds file data directly into a URL string. For images, it looks like data:image/png;base64,... and can be used in HTML img src or CSS url() without a separate file request.
What is the maximum file size?
This tool supports images up to 2MB. Larger files should be hosted separately for better performance and caching.
Should I embed all images as Base64?
No. Base64 encoding increases file size by about 33%. Use it for small icons and sprites. For larger images, traditional file hosting with caching is more efficient.
