Why does my data URL fail to convert?
It may be truncated, use an unsupported format such as SVG or GIF, or be missing the data:image prefix. Check that it was copied in full.
What file name will the download have?
The file is named image with the extension matching its type, for example image.png. Rename it after downloading.
