How Images to PDF works
Image to PDF combines one or more images, JPG, PNG or WebP, into a single PDF document, with each image placed on its own page. You control the page size and orientation, and the order of the pages matches the order you arrange your images before converting.
This is the reverse of extracting images from a PDF: here you are creating a PDF from pictures. For scanning-related workflows, pair it with the PDF Deskew and OCR tools to go from raw scan to searchable document. The output is an image-based PDF with no text layer, so run OCR on it afterwards if you need searchable text.
