img2pdf

Command-line lossless converter of raster images to PDF. More information: https://gitlab.mister-muffin.de/josch/img2pdf.

• Convert multiple images to a single PDF, each image being on its own page:

img2pdf {{path/to/image1.jpg}} {{path/to/image2.jpg}} --output {{path/to/file.pdf}}

• Convert only the first frame of a multi-frame image to PDF:

img2pdf {{path/to/file.gif}} --first-frame-only --output {{path/to/file.pdf}}

• Auto orient the image, use a page size of A4 in landscape mode, and set a border of 2cm horizontally and 5.1cm vertically:

img2pdf {{path/to/file.jpg}} --auto-orient --pagesize {{A4^T}} --border {{2cm}}:{{5.1cm}} --output {{path/to/file.pdf}}

• Shrink only larger images to a 10cm by 15cm rectangle inside a 30x20cm page:

img2pdf {{path/to/file.tiff}} --pagesize {{30cm}}x{{20cm}} --imgsize {{10cm}}x{{15cm}} --fit {{shrink}} --output {{path/to/file.pdf}}

• Convert an image to PDF, and specify metadata for the resulting file:

img2pdf {{path/to/file.png}} --title {{title}} --author {{author}} --creationdate {{1970-01-31}} --keywords {{keyword1 keyword2}} --subject {{subject}} --output {{path/to/file.pdf}}
