Image to Base64

Turn any image into a data URL and copy ready-made snippets for HTML, CSS and JSON.

Why embed images as Base64?

A data URL encodes the whole image into a text string, so the browser does not need a separate request to fetch it. That is handy for small icons, logos and CSS patterns: one less HTTP request, no broken image links, and a self-contained HTML file. The trade-off is size — Base64 is about 33% larger than the binary file, so use it for small images only, and avoid it for large photos.

Frequently asked questions

What size image is suitable?

As a rule of thumb, keep data-URL images under 10 KB (icons, small logos, textures). Larger images hurt page weight and can slow first render.

Does the image get uploaded?

No. The encoding happens in your browser — the file never leaves your device, so private images stay private.
