About the Image & Base64 Converter
Base64 encoding is an internet standard used to translate binary data (like images) into a long string of ASCII characters. By converting an image to a Data URI Base64 string, you can embed the image directly into HTML, CSS, or JSON files. This eliminates the need for separate image files and reduces HTTP requests, drastically speeding up web page loading times.
Embed Images Anywhere
The OnlinePaste.com Image to Base64 Converter lets you instantly transform PNG, JPG, WEBP, and SVG files into code. Use our settings menu to automatically wrap your Base64 string in an HTML <img> tag or a CSS background-image property for instant copy-pasting into your projects.
100% Secure & Local
Converting personal photos or proprietary UI assets? You never have to worry about data leaks. This entire encoding and decoding process utilizes HTML5 FileReader APIs and happens locally inside your browser. Your images are never uploaded, saved, or transmitted to our servers.
