            Bug ID: 207088
           Summary: Uploading photos from iOS photo library strips EXIF
                    data
           Product: WebKit
           Version: Safari 13
          Hardware: iPhone / iPad
                OS: iOS 13
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: henry at escapelab.com.au

In earlier versions of iOS, photos uploaded via Safari retained their EXIF data. In iOS 13, all EXIF data appears to be stripped out.

There does not seem to be any settings or options that allow the EXIF metadata to be included in the uploaded file - even if a user chooses to upload the 'Actual Size' image. Without EXIF data, it is impossible for a user to have a proper backup of their photo. It is also impossible for web apps to do even the most basic photo management, such as sorting uploaded photos by the date they were taken. 

Stripping out EXIF data also leads to the ridiculous situation where photos no longer have the correct orientation (https://bugs.webkit.org/show_bug.cgi?id=203482). 

Currently, for a user to upload an iPhone photo that includes EXIF data, they need to first transfer it to a computer via AirDrop or ImageCapture, and then upload it via a desktop web browser. 

If EXIF data is being deliberately stripped out for privacy purposes, it seems like there could easily be an option to include this data if the user wants to. Users are already able to select the size of the file to upload ('Large', 'Medium', 'Small' or 'Actual Size'), and this screen seems like the perfect place to give the user an informed choice about including EXIF data.
