Image to Base64
Encode any image into a Base64 data URI for CSS, HTML or JSON.
Knowledge Base & Educational Companion: Data URIs Explained
A Base64 data URI embeds an image directly inside your code as text, so the browser needs no separate network request to load it.
1. Fewer Requests
Inlining small icons or logos as data URIs removes extra HTTP round-trips, which can speed up first paint on simple pages.
2. The Size Trade-off
Base64 grows the payload by about 33%. It suits small assets; large images are better served as normal files with caching.
3. Where It Fits
Data URIs work in CSS background-image, <img> src, JSON payloads and email templates where external files are awkward.
