Photographing a document is quick. Sending someone fourteen separate images is not. Here is how to turn them into a single PDF that opens and prints like a real document.
Two things separate a usable photographed document from an obviously photographed one. The first is framing: crop each photo to the page edges before you build the PDF, so there is no desk, no hand and no shadow around the paper.
The second is contrast. A photo of white paper is rarely white, it is grey with a shadow across it. Running the images through the adjust tool with the clean scan preset lifts the contrast and flattens the shadow, which makes printed text read sharply.
Choose A4 or Letter pages rather than fitting the page to the photo. It means the document prints at a normal size on normal paper, which is usually the point of making a PDF at all.
This tool puts one photo on each page. If you want them side by side on a single sheet, merge the images first and then convert.
No. A photograph of text is a picture, not text. Making it searchable needs text recognition, which is not built yet.
