Image to Base64 Data URI Converter
Convert images to Base64 data URIs for embedding in CSS or HTML. Reduce HTTP requests; processing is done in your browser.
Your files are 100% safe. Processing is done in your browser; nothing is uploaded to any server.
How to use this tool & why it helps
Upload an image and get a Base64 data URI string. Use it in CSS as background-image: url(data:…) or inline in HTML to avoid extra HTTP requests for small icons and images.
Uses the browser FileReader API; nothing is uploaded to any server. Best for small assets; very large images can make CSS/HTML files big.
Paste the data URI in CSS or HTML. For production, consider using a CDN or optimized image URLs for large images.
