Image to Base64

A free browser-based image tool that converts images to base64 data URIs for inline embedding. Process your photos and graphics directly in your browser without uploading to any server. Embedding an image directly inside HTML, CSS, or a JSON payload usually means hunting down a command-line tool to generate the data URI. This encoder turns any image into a ready-to-paste Base64 string right in the browser, complete with the correct MIME-type prefix. The tool outputs a ready-to-paste Base64 data URI string (prefixed with the correct MIME type) as well as raw Base64, so you can drop it straight into an img src attribute, a CSS background-image property, or a JSON payload. File size and character count are displayed alongside the output. Choose a file from disk or paste an image from your clipboard, and the encoded string appears instantly in a text area with copy and download buttons. Toggle between raw Base64 and the full data: URI scheme depending on whether you need it for an img tag or an API field. The entire encoding pipeline runs through your browser's FileReader and btoa APIs. Neither the original binary nor the resulting string is sent anywhere, which is important when embedding private diagrams or internal screenshots into code.
