I have for long time being disapointed with evince pdf reader with it's lack of capacity to zoom in and out. The same happened with foxit reader and its lack of history management in its linux version.
Finally I discovered mupdf. It has a vi key biding, has a great zooming window, allows back in the history. The only missing feature is beeing able to follow links with keyboard as luakit does.

- i : dark mode
- / : search
- W : fit to page
- t : go back to last jump
→ Concatenating pdf
The command below is great to concat multiple pdf together. I had some problem with pdftk. You can also add a pdf title, and chose the pagesize
gs -dBATCH -dNOPAUSE -sPAPERSIZE=a4 -q -sDEVICE=pdfwrite -sOutputFile=merged.pdf mine1.pdf mine2.pdf -c "[ /Title (My New Title) /DOCINFO pdfmark"
Also this command allows to compress a large pdf into something smaller:
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/default -dNOPAUSE -dQUIET -dBATCH -dDetectDuplicateImages -dCompressFonts=true -r150 -sOutputFile=output.pdf input.pdf
It is also possible to split pdf with pdfbox:
java -jar /app/edsr/script/java/pdfbox-app-2.0.0-SNAPSHOT.jar PDFSplit ./authorisation-inscription.pdf
→ pdf generation
→ from html
weasyprint makes a brillant work to transform html page into pdf.
pip3 install weasyprint
weasyprint https://website/index.html index.pdf
→ Well structured pdfs
