About the Image to Base64
Base64 encoding turns an image into plain text. Developers use it to embed small icons and logos directly in HTML, CSS, emails or JSON, avoiding an extra file request.
Upload an image and choose the output: a full data URI, raw Base64, a ready-made HTML <img> tag or a CSS background rule. Then copy it with one click.

Frequently asked questions
Why is Base64 bigger than the image?
Base64 text is about 33% larger than the original binary file. Use it only for small images.
What is a data URI?
It is a Base64 string with a prefix like data:image/png;base64, that browsers can display directly.
Is it secure?
The conversion happens in your browser. Your image is not uploaded.
