Image to Base64 FAQs
Answers to common queries about image encoding, Data URIs, and performance.
Q.What is the difference between raw Base64 and a Data URI?
Raw Base64 is only the encoded string. A Data URI includes a metadata prefix (e.g., "data:image/png;base64,") which tells the browser the format and allows the string to be used directly in HTML "img src" or CSS "url()".
Q.Why should I convert my images to Base64?
Encoding images to Base64 lets you embed them directly inside HTML, CSS, or JSON files. This reduces the number of HTTP requests required to load a page, which can speed up page loads for small images/icons.
Q.Is my image data kept secure?
Yes. Our converter is 100% client-side, running in your local sandbox. No files are uploaded, making it completely safe for company assets, private documents, or sensitive keys.
