Command pdftocairo is an utility from poppler-utils package. It's a PDF to PNG/JPEG/PDF/PS/EPS/SVG converter using Cairo. I use this command to update a very old PDF from version 1.2 to 1.5, for example:
$ pdftocairo -pdf input.pdf output.pdf
The PDF version of the output PDF in my system is always 1.5:
- Linux Mint 21.1
- poppler-utils 22.02.0-2ubuntu0.1
- cairo 1.16.0
My questions:
1) Is possible to convert to a higher PDF version? Like 1.7?
2) There is ANY advantage in update a PDF version?
PS.: I have opened an issue in Gitlab's Poppler.
