#FAQ
Why would I convert an image to Base64? ▾
Converting an image to a Base64 data URI lets you embed it directly in HTML or CSS without a separate file request. This is useful for small icons, logos, and email templates where reducing HTTP requests improves load performance.
Does Base64 encoding increase the image file size? ▾
Yes, Base64 encoding increases the data size by approximately 33% compared to the original binary file. It is best suited for small images under 10 KB where the savings from eliminating an extra network request outweigh the size increase.
