About this tool

Reads the image with the browser's FileReader API and produces a data: URL you can paste straight into CSS or HTML — useful for small icons, email templates, or single-file demos where an extra HTTP request isn't worth it. Base64 encoding adds roughly 33% to the file size, and inlined images can't be cached separately, so the tool warns you when a file is over 100 KB — at that point a normal image file is almost always the better choice.

Your image never leaves the page — there is no server, no upload, and no tracking of tool inputs. The conversion happens entirely in your browser's memory.
