Frequently Asked Questions
What is Base64 encoding?
A way to represent binary image data as text, so it can be embedded directly in HTML, CSS, or JSON.
Why would I use Base64 images?
To embed small images (icons, logos) directly in code, reducing HTTP requests and simplifying deployment.
Are Base64 images larger?
Yes, about 33% larger than the original binary file. Use only for small images.
How do I use the Base64 string?
In HTML: <img src="data:image/png;base64,...">. In CSS: background-image: url(data:image/png;base64,...).
Is there a size limit?
Technically no, but keep Base64 images under 10KB for best performance. Large images hurt page load speed.
