About this image tool
A data URL contains the image media type and a Base64 representation of the file bytes. It can be convenient for small icons, prototypes and isolated examples. For large images, embedding Base64 usually makes source files harder to read and can increase the size of HTML, CSS or JavaScript. For production websites, normal image files with descriptive names and caching are often easier to maintain.
Frequently asked questions
What is a Base64 image data URL?
It is text that includes a media type and an encoded representation of the image bytes, allowing the image to be embedded in supported contexts.
Does Base64 make an image smaller?
No. Base64 usually increases the amount of text needed to represent binary data. It is an encoding method, not an image compression method.
Can I use the result in HTML?
Yes. The generated value is a data URL that can be used in supported HTML and CSS contexts. Consider file size and caching before using it on a public site.
