Image to PDF

Combine multiple images into a single multi-page PDF — one image per page.

PDF is a page description format, so combining images means deciding a page size and how each image sits on it. One image per page with the page matching the image avoids the letterboxing you get from forcing landscape photographs onto portrait A4.

The reason to reach for this is that PDF is the format institutions accept. Scanned documents, receipts and forms tend to arrive as a handful of phone photographs, and every office system on the other end wants one file. Note that the images stay images — the result is not searchable text unless something runs OCR over it separately.
