Frequently asked questions

What does a data URI look like?

It starts with data:, then the MIME type and ;base64, followed by the encoded data, for example data:image/png;base64,iVBORw0KGgo…

How is the image type detected without a prefix?

Every image format starts with a recognisable signature ("magic bytes"). For example PNG starts with 89 50 4E 47 and JPEG with FF D8 FF.

Why do I get an "invalid Base64" error?

The string may be truncated, contain characters outside the Base64 alphabet, or not be an image at all. Make sure you copied the whole value.
