Frequently Asked Questions
QWhat is a Data URI?
A Data URI allows image binary data to be encoded directly into text (Base64) and embedded inside HTML or CSS files, eliminating separate HTTP image requests.
QWhen should I use Data URIs?
Data URIs are ideal for small icons, logos, email signatures, single-file HTML landing pages, and reducing server network requests.
QAre my images secure?
Yes! The FileReader API converts your image strictly inside your local browser memory. No data is transmitted across the internet.
