Frequently Asked Questions
What is a Base64 Image?
Base64 is an encoding algorithm that translates binary data (like an image) into a text string format. This string can be embedded directly into HTML or CSS files, eliminating the need to host the image separately.
Why should I convert images to Base64?
For tiny images like icons or logos, Base64 conversion is highly beneficial because it prevents the browser from making an additional HTTP request to a server, thus speeding up the initial page load time.
Are my images uploaded to your servers?
Absolutely not. The Image to Base64 conversion happens entirely via JavaScript FileReader APIs in your web browser. This means you can confidently convert sensitive or proprietary images without risk.
