Power Platform Community Forum Thread Details

Hi All,

I have an application to generate field visit reports. I upload photographs in several image boxes, which I then send embedded in the body of an email using Power Automate and HTML code.
The problem is that sometimes when the images are large, an error occurs. Is it possible to somehow take the photographs that are uploaded and reduce their size so that it is the maximum allowed by P. Apps?.

Thanks,

Francisco

Building Power Apps

Yes, you can reduce the size of uploaded images in PowerApps before sending them via email. Here are a few approaches:

1. Use PowerApps Inbuilt Compression (Recommended)

PowerApps provides an inbuilt function to resize images before saving or sending them.

When using an Add Picture control (Image1), set its OnChange property to:

ClearCollect(
    colCompressedImages, 
    { 
        ImageData: UploadedImage1.Image,
        CompressedImage: Substitute(JSON(UploadedImage1.Image, JSONFormat.IncludeBinaryData), """", "")
    }
)

Use CompressedImage in Power Automate instead of the raw image.

2. Reduce Image Resolution Before Sending

Instead of embedding full-sized images, you can adjust their size using the Resize function:

Resize(UploadedImage1, 500, 500)

This resizes the image to 500x500 pixels, reducing file size.

3. Convert Image to Base64 with Lower Quality

If using JSON format to send images, reduce image quality:

JSON(Resize(UploadedImage1, 500, 500), JSONFormat.IncludeBinaryData)

This keeps the image under control while keeping it embeddable in HTML.

4. Use Power Automate for Further Compression

If images are still too large:

Save them to OneDrive/SharePoint first.

Use a Power Automate "Compress Image" action (if using AI Builder or third-party APIs).

Retrieve the compressed version for email.
