Frequently Asked Questions
What is Base64 image encoding?
Base64 image encoding converts binary image files into ASCII text characters. This allows images to be embedded directly inline inside HTML files, CSS stylesheets, JSON payloads, or email templates without requiring separate HTTP file requests.
Does Base64 encoding increase file size?
Yes. Base64 encoding typically increases binary file size by approximately 33% due to representing 3 bytes of binary data using 4 ASCII characters. It is best used for small icons, logos, and critical inline UI graphics.
What formats can I export with this tool?
You can export Data URIs (data:image/png;base64,...), Raw Base64 strings, complete HTML <img> tags, and CSS background-image: url(...) declarations with 1-click clipboard copy.
Are my confidential graphics or photos sent to an external server?
No. The entire encoding process occurs locally inside your web browser using the HTML5 FileReader API. Your images never leave your machine.
