Download function in Power Apps

Downloads a file from the web to the local device.

Description

The Download function downloads a file from the web to the local device.

In native players (Windows, Android, and iOS), the user is prompted for a location to save the file.

When used on the web, Download is dependent on the browser's settings to determine what happens with the file. For images, videos, and other file types that the browser natively supports, a new browser tab is opened to display the file.b Many browsers support saving the contents to the local file system.

Only on Windows, Download returns the location where the file was stored locally as a text string.

Download can only be used in behavior formulas.
