Image to Base64 Converter

Encode any image into a Data URI string for CSS or HTML use.

Optimize Web Performance with Base64

Base64 encoding is a method used to embed image data directly into your HTML or CSS code. This technique eliminates the need for separate image file requests, which can significantly speed up the loading time for small assets like icons, patterns, and logos. Our Image to Base64 tool is 100% secure, as the conversion happens in your browser and your images are never uploaded to our servers.

Frequently Asked Questions

Does Base64 increase file size?

Yes, Base64 strings are typically about 33% larger than the original binary image file. This is why it is best used for small graphics rather than large high-definition photos.

Which image formats are supported?

Our tool supports all major formats including PNG, JPG, JPEG, GIF, SVG, and WebP.

Is Base64 good for SEO?

Used correctly for small decorative icons, it can improve SEO by reducing the number of server requests (HTTP requests), thus improving your Google PageSpeed score.
