Frequently asked questions

What if my Base64 has no data: prefix?

That works too. The format is detected from the first bytes of the image data.

Why do I get an error?

The text may be cut off, contain extra characters, or not be an image. Make sure you copied the complete string.

Is my data uploaded?

No. Decoding happens in your browser.
