About Image to Base64 Converter
A Base64 data URI turns an image into a long string of text that can be embedded directly inside HTML, CSS or JSON — no separate image file and no extra network request. Developers use it for tiny icons, email templates, inline SVG fallbacks, or bundling a small image into a single file. Instead of <img src="logo.png"> you write <img src="data:image/png;base64,iVBOR…"> and the picture travels with the markup.
When to use it — and when not to
Base64 strings are about 33% larger than the original file, so they suit small images only. For a 2 KB icon the convenience wins; for a 2 MB photo, the bloated string slows your page and bloats your CSS — link the file normally instead. This tool reads the image locally and never uploads it, so even private images are safe to encode.
