Boad Tools Image to Base64 converter allows developers to instantly encode image files into Data URI strings, HTML <img> elements, and CSS background-image rules, or decode raw Base64 strings back into downloadable images.
Why use Base64 for images?
Base64 encoding embeds images directly into HTML and CSS files as text. This eliminates extra HTTP requests, which is ideal for small icons, email templates, avatars, and single-file web pages where external image loading could fail or slow down rendering.
How to use this tool
- To Encode: Select the "Image to Base64" tab. Drag and drop any image file (PNG, JPG, WebP, SVG, GIF).
- Copy Code: Instantly copy the complete Data URI, HTML <img> snippet, or CSS background snippet with one click.
- To Decode: Select the "Base64 to Image" tab. Paste your Base64 string or Data URI to preview and download the rendered image file.
