Use It Selectively
Base64 is best for tiny icons, email assets, and one-file demos. Large images grow quickly and usually perform better as normal URLs.
Image to Base64 Converter
Convert image files into Base64 and data URI strings with ready-to-copy HTML and CSS snippets for embeds, email templates, and one-file demos.
Image Tools
Upload an image to generate Base64, full data URI, HTML embed, and CSS background snippets.
Browser Only
Encoding is done locally in the browser, so the source image never leaves your device while you generate the snippets.
Copy the Right Output
Keep the full data URI only where needed. For CSS and HTML, copy the dedicated snippet blocks to avoid formatting mistakes.
