Turn a picture into a data URI you can paste straight into HTML or CSS — no image files, no extra requests.
Add your image — drag it into the tool or click Select File to browse.
The encoder converts the file to a Base64 string instantly.
Copy the ready-made snippet: an data URI or a CSS background-image value.
Paste it into your HTML or stylesheet — done.
Built for speed, privacy and reliability — on any device.
Get the full data:image/...;base64 string formatted for tags and CSS backgrounds.
Inlined images skip a server round-trip — handy for tiny icons and logos.
Encoding runs locally in your browser — assets never reach a server.
Icons, avatars and badges — the stuff that belongs inline, not hero photos.
No account, no limits, no strings.
Add the image to the tool above. The Base64 string and ready-made HTML/CSS snippets appear instantly — free, no account.
Embedding an image directly in code: an img tag with a data:image source, or a CSS background. The image travels inside the document itself.

No. The encoding runs entirely in your browser, so the file never leaves your device.
The tool works in all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari and Opera. We recommend keeping your browser up to date for the best experience.
