Image to Base64
Encode an image as a Base64 data URI.
Encode Images as Base64
Base64 encoding turns an image into a text string you can embed directly in HTML, CSS, or JSON â no separate file needed. This tool converts any image to a Base64 data URI in your browser.
When to use it
- Inline small icons in CSS or HTML
- Embed images in JSON or data files
- Avoid extra HTTP requests for tiny assets
- Email templates that need self-contained images
Size caveat
Base64 increases data size by about 33%, so it's best for small images. Large images are better served as normal files.
Private & Processed Locally
Encoding happens entirely in your browser; your image is never uploaded.
