How to use Convert PNG to Data URI
- 1. Drop in your PNG. Add the image you want to inline, such as a small icon or background graphic you plan to embed directly in HTML or CSS.
- 2. Let the tool build the data URI. It encodes the file's bytes as Base64 and wraps them with the data:image/png;base64 prefix, producing a complete, self-contained URI.
- 3. Copy the data URI. Copy the resulting string and paste it wherever a normal image URL would go, such as an img src attribute or a CSS background-image property.
When to use Convert PNG to Data URI
Convert PNG to Data URI packages an image into an inline data: URI for HTML or CSS backgrounds. It removes the need for a separate image file and network request, which matters for small icons and single-use graphics.
- Embedding a background image in CSS. You want a small background pattern or icon inlined directly in your stylesheet to avoid an extra HTTP request, and a data URI drops straight into a background-image rule.
- Sending an image inside an email template. Email clients often block external images by default, and inlining a small logo as a data URI ensures it renders without depending on remote image loading.
- Shipping a self-contained HTML file. You are building a single-file HTML document that needs to work without any external assets, and inlining its images as data URIs keeps everything in one file.

About the Convert PNG to Data URI tool
Convert PNG to Data URI runs as plain JavaScript in your browser tab, with no server behind it. Package a PNG into an inline data: URI for HTML or CSS backgrounds. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's PNG Tools section, 108 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.
