About Image to Base64
Encode an image as a data URI string you can paste into HTML <img src=...> or CSS background-image. Useful for tiny icons where avoiding an extra HTTP request matters.
Frequently asked questions
Should I always inline images?
No. Inlining beats a network request only for images under ~2 KB; bigger images bloat the HTML and aren't cached separately.
Does it work for SVG?
Yes, and SVG inlines especially well because it's text-based and shrinks well under gzip.
