Image Data URI Converter — For Developers

Convert images to data URIs for embedding inline in HTML, CSS, or JSON. No server upload required.

Convert images to data URIs for embedding directly in HTML and CSS. Data URIs eliminate extra HTTP requests by inlining image data as Base64 — useful for small icons, logos, and email templates where external image hosting isn't available.

Drop an image to encode

Supports JPG, PNG, WebP, GIF, BMP

🔒100% Private — Your files never leave your device. All processing runs locally in your browser.

How It Works

In encode mode, drop an image file and the tool instantly converts it to a Base64 data URI using the browser's FileReader API. Copy the full data URI (with MIME prefix) or the raw Base64 string.

In decode mode, paste a Base64 string or data URI and the tool renders the image for preview and download. No server required — everything runs in your browser.
