About the Image to Base64 tool
Image to Base64 encodes your picture as a text string you can embed directly in HTML or CSS. This removes the need for a separate image file, which is handy for tiny icons, email templates, or single-file web pages. The Image to Base64 tool converts the file instantly in your browser and gives you copy buttons for both the raw string and a ready CSS rule.

Frequently asked questions
What is a Base64 data URI used for?
It lets you embed an image directly in code, avoiding an extra file request.
Is Base64 good for large images?
It works best for small images; large ones create very long strings and increase file size.
Is my image uploaded to convert it?
No, encoding happens entirely in your browser.
