Frequently Asked Questions
What is a Base64 DataURL and why would I use it?
A Base64 DataURL is a way to represent an image as a string of characters. It lets you embed images directly into your CSS or JavaScript code, avoiding the need to load them from external files. This can be useful for small icons or images.
How do I use the generated Base64 or DataURL?
Simply copy the code provided after converting your image and paste it into your CSS or JavaScript. For example, in CSS, you could use it like this: background-image: url('data:image/png;base64,...');
What image formats does this tool support?
This tool is specifically designed for PNG images. Other formats might not convert correctly.
Why are large images not recommended?
Large images create very long Base64 strings, which can slow down your computer and increase page load times. It's best to use this tool for smaller images.
Is there a limit to the size of the image I can upload?
While there isn't a strict file size limit, performance will degrade with larger images. We recommend using smaller PNG files for best results.
