Frequently Asked Questions
What is Base64 Image Encoding?
It is a method of converting image data into a text string. This allows you to include image data directly in your source code rather than linking to an external file.
Is my image data kept private?
Absolutely. The tool uses the JavaScript FileReader API to process files locally. Your images are never uploaded to our servers or stored anywhere.
Does it support SVG and WebP formats?
Yes, it supports all modern web formats including SVG, WebP, PNG, JPG, and GIF. SVGs encoded this way are particularly useful for CSS background icons.
Are there file size limitations?
The tool is optimized for assets under 5MB. While Base64 is great for small icons, using it for very large photos can significantly increase your file sizes and is generally discouraged.
How do I use the code in CSS?
Simply paste the copied string into your CSS property like this: background-image: url(‘data:image/png;base64,…’);
Does Base64 encoding improve SEO?
Indirectly, yes. By reducing the number of HTTP requests required to load a page, you can improve your PageSpeed Insights scores, which is a known ranking factor.
