Frequently Asked Questions
Does Base64 make the image bigger?
Yes. Base64 text is about 33 percent larger than the original binary file, so it is best for small icons and logos rather than large photos.
How do I use the data URL in HTML?
Paste it as the src value, for example: img src="data:image/png;base64,..." with the rest of the text after the comma.
