Assemble photos or scans into a single PDF, in the order you choose, with page size and orientation handled for you.
Photographing a signed form or a receipt and sending five loose JPEGs is a guarantee that one will be lost. Converting them to a single PDF in the right order produces something that behaves like a document: one file, page numbers, consistent size.
Fitting every image to A4 with a small margin produces a tidy, printable file. Keeping each page at the image's own proportions is better when the pictures are already correctly framed and you do not want white borders. For a tall phone photo of a page, automatic orientation saves a page that opens sideways.
The converter does not improve a blurry photo. Shoot straight, fill the frame, and use even light: that fixes more than any setting. Very large photos make a very large PDF — compress afterwards if it must be e-mailed.
Yes, image inputs can be mixed as long as each file is a supported picture format.
Yes — A4 or letter, portrait or landscape, with an optional margin.
Images are embedded at their original resolution, so nothing is upscaled or lost.
