Cedo, antes de lidar aqui, estava começando um pequeno #script #Bash para facilitar o cotidiano do #qpdf para remover a #senha de #contas recebidas, antes de guardá-las. 🗄️

O que costumo fazer até agora é abrir o #PDF no #Evince (leitor de PDF do #GNOME) e então "imprimi-lo" como PDF. Isso pode ser feito pelo navegador também, mas, ao menos no #Firefox, aparentemente o texto se torna imagem: arquivo maior e menos legível.

Há um app "unlockR" no #flathub que faz isto, porém ainda bem rudimentar.

QPDF: A Content-Preserving PDF Transformation System https://qpdf.sourceforge.io/ #linearization #encryption #library #merge #split #qpdf #file #c++ #pdf

#qpdf is one of the greatest tools in my everyday life.

https://qpdf.sourceforge.io

I use it for merging certain pages of multiple PDF files to a single one.

#qpdf #pdf

Again looking at #PDF things at work (malicious PDFs, content/mime-type detection). And again and again I just *love* #QPDF

Basically, QPDF is a tool to "convert" any PDF into... PDF. Many PDFs are often binary files (due to compression and embedding of binaries), this is a hassle to edit/manipulate (my use case). But it's possible to make any PDF a "plain text file" that's also a valid PDF. QPDF does just that. You can then edit tags, extract info, delete watermarks *cough*, etc., with your text editor. The resulting PDF ain't correct anymore, likely (offsets and jumps addresses being wrong) but you can ask QPDF to recalculate them – et voila!

@caiocgo @massa #qpdf does everything I'ce ever needed to to with pdfs It's CLI and very powerful
