3 ways to download media from the PowerApps app

Redownloading the media from PowerApps app is no longer available out of the box. Let’s explore the workarounds we have!

Together with my colleague Dhaval, I was working on the PowerApps app. I uploaded the image to the media library. I was surprised when he told me to send him the image via Teams. He wanted to use it with another app.

I was sure that exporting media from the app was available for a long time. It turns out it's not and you need to use workarounds to get the media to your machine.

In this article, we'll go through different ways to export media from the PowerApps app.

Requirements

We'll need:

• Microsoft 365 account with PowerApps license

• Some images to upload

• Browser

Preparing

For this article, I have created a canvas app with two images. One is my son's drawing and the other is 4K wallpaper from the Bing Wallpapers archive.

This is what the app looks like:

When I go to the media library in the app, I can see that there is no option to export the media:

Accessing media with browser dev tools

Our first option to download the media is to use browser dev tools. We need to play our app first. We can do that by accessing its link or using the Play* *button (top-right corner of the editor):

From here we can right-click the image and choose Inspect:

The Inspect option will open dev tools. It'll automatically select one of the elements close to the image:

From here we need to scroll up and find the img element. It'll have the src property that stores the hyperlink to our image:

Now when we hover over the hyperlink we'll have the option to open it in a new tab. Let's click the hyperlink:

From here we can save it:

Saving the app as a webpage

An alternative option is to save the app as HTML. That option is usually tied to ctrl+s shortcut. We only need to remember about choosing Webpage, complete as a file type:

As a result, we'll have the HTML file and the folder containing all the files:

The folder contains many files and our two images:

Exporting the entire app

In the PowerApps portal we have an option to export the entire app. Let's click the three dots and choose Export package:

From here we need to put any name (1) and click the Export button (2):

We'll get the ZIP file. Let's extract it:

We follow the extraction wizard with default options. Now we need to go to the folder and find the file with .msapp extension. It will be under Microsoft.PowerApps > apps > guide (long number). Go to the folder (1) and find the file (2):

Rename the file to .zip and confirm:

The .zip file will have all the images under Assets > Images:

Tip

We can get the .msapp file directly from the PowerApps editor. Click the dropdown next to the Save button (1) and choose Download a copy (2):

Comparing files with PowerShell

We have the file. But is it exactly the same as our source file?

We can check the file properties and see that the resolution and dimensions are the same for both files.

But, wait for a second. This is a technical blog. Why don't we compare the files in a more techy way? We can use Get-FileHash to compare these two images:

$originalFilePath = "$Home\Downloads\ChengduPanda.jpg"
$downloadedFilePath = "$Home\Downloads\Test app with image - PowerApps_files\46e410ea-361e-4495-83b9-1530fcecfb95.jpg"

# Calculating hashes
$originalFileHash = Get-FileHash -Path $originalFilePath 
$downloadedFileHash = Get-FileHash -Path $downloadedFilePath

# Comparing
if ($originalFileHash.Hash -eq $downloadedFileHash.Hash) {
  Write-Host "Files are the same" -ForegroundColor Green
} else {
  Write-Host "Files are different"-ForegroundColor Red
}

Warning

Remember to compare Hash properties. If we try to compare $originalFileHash and $downloadedFileHash variables directly, they will never be the same. It is because the object returned by Get-FileHash also has the Path property. The path of two different files will always be different.

Summary

Luckily for us, Microsoft doesn't do any compression of the images uploaded to the PowerApps app. (But remember, it might change anytime in the future.) Thanks to that, we can easily recover the files we uploaded to PowerApps, if we lost their local copy.
