How it works
The Data URI to Image Converter decodes a base64 or URL-encoded data URI and renders the encoded image as a visible preview — showing the image it contains without needing to write it to a file or open a new browser tab.
Data URIs embed binary file content directly in text format. They appear in CSS stylesheets (background images), HTML attributes (src, href), JavaScript variables, and API responses. When you encounter a data URI and need to see what image it contains, this tool decodes and renders it instantly.
How to use it: paste any data URI string (data:image/png;base64,... or data:image/svg+xml,...). The tool decodes the content and displays the rendered image. It shows the image dimensions, file type, and decoded file size. Download the image as a file using the Download button.
Supported formats: PNG, JPG, GIF, WebP, SVG, ICO, BMP, and any other image format your browser can render. The tool passes the decoded data directly to an <img> element, so browser support determines what renders.
Debugging use: when you see a data URI in a CSS file or JavaScript bundle and need to verify it's the correct image, this is faster than writing a temporary HTML file to test it.
Frequently Asked Questions
- Any image format your browser supports: PNG, JPG, GIF, WebP, AVIF, SVG, ICO, and BMP. The tool passes the decoded data to an img element — browser support determines what renders.
- The prefix is optional. If you paste a bare Base64 string without the data URI prefix, the tool tries PNG, then JPG, then WebP until one renders. For best results, include the full data URI with the correct media type.
- Yes. Copy the entire data URI value from the CSS — including the data:image/...;base64, prefix through the last character before the closing quote — and paste it into the tool.
- Yes. Build tools often inline small icons as data URIs in CSS bundles to save HTTP requests. This tool lets you decode and see what image each data URI contains without extracting and saving it manually.
