In iOS 13 (maybe 12?) you can scan documents using the files app. It uses the camera, manually or automatically crops, allows multiple pages, and produces a PDF. A very large PDF.
My single A4 page is 10MB. A drivers license 4MB. It’s too big for uploading to some sites.
Is there a way to reduce the file size, either while scanning or after the fact? Specifically without using a 3rd party app (there’s lots and my expectation was to avoid the need for these with a built in feature).
