How to convert images to PDF
- Tap Choose your images and select everything you want in the document.
- Pick a page size — Fit keeps each page the shape of its image, A4 makes a standard sheet.
- Tap Make PDF and save it.
Mixed formats are the normal case
Real evidence for an application is rarely all one thing. A screenshot of a payment confirmation is a PNG, the photograph of the receipt is a JPG, and the image the bank’s website let you save is a WebP. Every one of them is a picture, and a converter that refuses two of the three is making you do its work.
Each image is stored in whichever way produces the smaller page — as a photograph or losslessly — decided per image rather than per document. A screenshot of text and a photograph of a face genuinely want different treatment, and in a mixed set they each get it.
Page size, and when to change it
Fit is the default and makes each page exactly the shape of its image. It produces the smallest file and it never leaves a band of white around anything. Choose A4 when the document will be printed, or when a form explicitly says A4 — then every page is the same standard sheet and images are centred inside it.
Margins matter more than they look. Zero is right for a scan that already has its own white border; a small margin is worth adding when the photograph runs right to the edge of the paper, because printers cannot reach the edge of a sheet.
