How to use Convert Image to Data URI
- 1. Upload the image. Drop in the icon or graphic you want to inline. Its bytes are read and prepared for encoding into a self-contained text string.
- 2. The tool builds the data: URI. There is nothing to configure. The file is Base64-encoded and wrapped with a data:image/…;base64, header describing its MIME type, producing one complete string.
- 3. Copy the data URI. Copy the full string and paste it directly into a CSS background-image, an HTML img src attribute, or anywhere an inline image reference is accepted.
When to use Convert Image to Data URI
Convert Image to Data URI wraps an image as a self-contained data: URI you can drop straight into CSS or HTML without hosting a separate file. It suits small icons and graphics where saving an extra network request matters more than file size.
- Inlining a small icon in CSS. A stylesheet needs a tiny background icon without adding another file to the build, and pasting in a data: URI keeps the icon bundled directly in the CSS.
- Embedding a logo in an HTML email. An email template cannot rely on external images being loaded by the recipient's client, so embedding the logo directly as a data: URI keeps it visible regardless.
- Sharing a self-contained code snippet. A single-file demo or CodePen needs to show an image without hosting it anywhere, so converting it to a data: URI keeps the whole demo in one portable file.

About the Convert Image to Data URI tool
Convert Image to Data URI runs as plain JavaScript in your browser tab, with no server behind it. Wrap an image as a data: URI you can drop straight into CSS or HTML. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Image Tools section, 200 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
