Convert Data URL to File

Convert Data URL to File decodes an embedded base64 value and returns a file with the matching MIME type.

Input and output

Direction	Field	Type	Description
Input	Data URL	String	A base64 URL such as `data:image/png;base64,...`.
Output	File	File	The decoded file.

The output is named converted.EXTENSION, where the extension is inferred from the MIME type.
