PDF edit size and convert other document types to pdf

Hello,

I need a software that can reduce pdf size and convert other types of documents in to pdfs for manjaro.

Im using manjaro KDE.

Perhaps have a look at pdfsam.
Though, the ‘reduce size’ functionality might be part of the non-free version.
At least they offer a 14days trial, so you can check.

Hi. you can check masterpdfeditor and masterpdfeditor-free from AUR.
Also calibre has a lot of options to convert document formats.

Please forgive my non-free recommendation, but in case you want that flavor:

I cannot recommend any higher the PDF Studio app by Qoppa.

I have used it for years in many OS’s and it fits our needs.
No affiliation with company. Just like it.

Good luck!
