CBZ and image folders to PDF
One page per image, in reading order, with the pictures untouched. This is the right output for a large screen, for printing, and for anything that has to open on a computer that has never had a comic reader installed.

Output format
PDF — Fixed pages. Looks identical everywhere and cannot reflow to a small screen.
The images are never resampled. This only decides how big a page is measured to be, which is what a printer and a page-fit view use.
Nothing is re-encoded
A JPEG page goes into the document byte for byte — the PDF image stream and a .jpg file are the same JPEG data, so there is no second generation of compression and no quality decision taken on your behalf.
A PNG page is decoded and stored losslessly, with transparency preserved as a soft mask, so a page with a transparent margin still looks right.
What it will not do
It will not turn a book of text into a PDF. That means rendering type at some fixed size and embedding fonts, and the result is a fixed-page document made from a book that reflows — worse to read on a phone than the book already was.
Pages in formats a browser cannot hand over as raw data — WebP, GIF, AVIF — are reported by name and count rather than replaced with blanks. Those convert fine to EPUB.
Metadata
The title, author, keywords and language from the archive’s ComicInfo.xml are written into the PDF’s document properties, encoded so that titles outside the Latin alphabet survive intact.
