Image to Base64 URI
Convert an image to a Base64 data URI for embedding in code.
An image as text you can paste
A data URI encodes an image as a text string that can be embedded directly in HTML or CSS, so the image travels inside the code rather than as a separate file. This converts an image to a Base64 data URI, in your browser.

When embedding an image helps, and when it doesn't
Embedding a small image directly in code has a real advantage: it removes a separate file request, so the image loads as part of the page rather than requiring the browser to fetch another file, which can speed things up for tiny images like icons. It also makes a snippet self-contained, carrying its image with it. But there is a clear trade-off — Base64 encoding makes the data noticeably larger than the original file, so it only makes sense for small images. Embedding a large image bloats the code and actually hurts performance, so bigger images are better left as normal linked files. The sweet spot is small icons, simple graphics and tiny decorative images. Converting locally in your browser means the image is encoded without being uploaded, keeping the process private, which is a nice bonus for anything you would rather not send to an online converter.
Frequently asked questions
Why embed an image as a data URI?
It removes a separate file request, so a small image loads as part of the page, and makes a code snippet self-contained.
When should I not embed an image?
For large images — Base64 makes the data bigger than the file, so embedding a large image bloats the code and hurts performance. It suits small icons and graphics.
Is my image uploaded?
No. The conversion happens in your browser.
