Convert images (PNG, JPG, WebP, GIF, BMP, SVG) to Base64 encoded strings and Data URIs instantly in your browser. Fast, secure, and 100% local processing.
Base64 is a binary-to-text encoding scheme that represents binary data (such as images) in an ASCII string format. It is commonly used to embed small images directly into HTML or CSS files, reducing the number of HTTP requests required to load a page.
A Data URI is a URI scheme that allows content creators to embed files inline in web pages. It takes the format "data:[mime-type];base64,[data]" and can be used directly as an image src attribute, CSS background URL, or even in JavaScript arrays.
Base64 encoding represents every 3 bytes of binary data using 4 characters. This results in an approximate 33% increase in file size compared to the original binary file. It is recommended to use Base64 mainly for small icons and decorative graphics.
You can copy the pre-formatted HTML <img> tag (e.g., <img src="data:image/png;base64,...">) or CSS background-image style (e.g., background-image: url(data:image/png;base64,...)) generated by this tool directly into your HTML/CSS files.
Yes. The tool is fully responsive and optimized for both desktop and mobile layouts. You can take photos or upload files directly from your smartphone or tablet.
No. All conversions are performed entirely inside your browser using the HTML5 FileReader API. Your images never leave your local device, ensuring maximum privacy and security.
This online utility helps developers, web designers, and content creators convert images to Base64 strings. It handles PNG, JPG, WebP, GIF, BMP, and SVG files locally. SVG files are processed with special encoding to preserve vector properties and UTF-8 characters properly. Use this tool to embed icons, inline images, and CSS background resources safely without worrying about server-side uploads.
