Instantly decode Base64 encoded image data into a JPG image directly in your browser. No uploads, no tracking, and complete privacy.
The Base64 Decode JPG tool allows users to transform Base64 encoded image strings into real JPG image files. All processing happens directly inside your web browser, ensuring complete privacy and security. No data is uploaded to any server.
Base64 encoding increases the size of image data by about 33%, which is why decoded JPG files are always smaller than their Base64 encoded versions.
Base64 encoding was originally developed to safely transmit binary data through systems that only supported text content, such as early email protocols. Over time it became widely used on the web for embedding images, documents, and other binary assets directly inside HTML, CSS, and JSON. Tools like this decoder continue that legacy by making it simple to reverse the process and recover original files.
