It will extract the image and display the result in the results box.Ī source file that contains Base64 text can be selected or dragged and dropped from the desktop and the contents will be loaded The tool can also Base64 decode images from a data URL format. Nothing is stored or transferred to the server. The decoding function is a JavaScriptīase64 decoder that does all decoding locally in the browser. The tool will convert a base64 string back to the original text or binary data.

An in depth breakdown of the Base64 encoding scheme and how it works. Start by uploading an image file above and play with the different possibilities.Related Base64 Encoder and Data URL Image Encoder Copy your source and paste into Base64 Encoder. Other file types like XML and JSON also supports Base64 encoded images. Or you can insert the string as a background-image in CSS: background-image: url("data:image/png base64,iVBORw0KGgoAAAANSUhEUgAAALQAAAC0CAYAAAA9zQYyAAAABGdBTUEAALGPC/xhBQAAAAlwSFlzA.") The string can be used instead of an URL in the src attribute of the img element in HTML: Once converted to Base64, encoded image data will look similar to this (shortened for simplicity): iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGPC/xhBQAAAAFzUkdCAK7OHOkAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwAADqYAAAOpgwnLpRPAAA. You should primarily use Base64 for small images and always test both embedded and external images to see what works best. A Base64 representation of an image is larger than a separate image and the string gets very long for large images. By including image data within an HTML document, the browser doesn't need to make an additional web request to fetch the file, since the image is already embedded in the HTML document. ![]() Base64 is most commonly used as a MIME (Multipurpose Internet Mail Extensions) transfer encoding for email.īase64 images are primarily used to embed image data within other formats like HTML, CSS, or JSON. The characters generated from Base64 encoding consist of Latin letters, digits, plus, and slash. Enable the Optimize image toggle and we will automatically optimize the image before encoding it.īase64 is an encoding algorithm that converts any characters, binary data, and even images or sound files into a readable string, which can be saved or transported over the network without data loss. You don't even need to run the image through optimization before generating the data. Simply drag and drop, upload, or provide an image URL in the controls above and the encoder will quickly generate a Base64 encoded version of that image. With elmah.io's free image to Base64 encoder, it's easy to copy and paste markup or style for exactly your codebase.
