An Image to Base64 converter allows you to encode image files (JPG, PNG, GIF, WebP, SVG and more) into a Base64 data URL that can be embedded directly into HTML, CSS, or JSON. Base64 encoding transforms binary image data into text, enabling you to include images inline without needing to host the file separately. This is especially useful for embedding icons, small graphics, email templates, or generating portable JSON payloads. The output includes the correct MIME type (for example, data:image/png;base64,...) so you can paste it instantly into <img>, CSS background-image, or API requests.
