CSS Image Encoder is a handy little utility that allows you to encode your website's images into base64 code. Ideal for encoding smaller images, base64 encoding could potentially turbocharge your website (depending on how many images it has), as the images you reference will be loaded from the base64 code and not from an external resource, which could drastically increase the rendering speed of the page (depending on the image size converted). CSS Image Encoder offers the following features:

-CSS Image Encoder supports five different file formats, including jpeg, jpeg2000, gif, png & bmp.
-Preview encoded images right from the app in your web browsers before exporting them.
-CSS Image Encoder can export your base64 code as a class into a stylesheet that you provide or can create a new stylesheet altogether.

Important Note: It is recommended that you convert small to medium sized images into base64 only.
