FAQ
What is a Data URL?
A Data URL is a URI scheme that allows data to be embedded in-line in web pages. It starts with 'data:' followed by the MIME type and the Base64-encoded string.
Does UtilVox store my images?
No. All conversions happen locally in your browser's memory. Your files never leave your computer, ensuring total privacy and security.
Will Base64 improve my SEO?
It depends. While reducing HTTP requests can improve site speed, excessive Base64 use can bloat your CSS/HTML and slow down parsing. Use it surgically for icons and small UI assets.
