I Created a Tool That Combines Multiple PDF Pages into One!

if you want to try the tool but you don't have a pdf file you can create a pdf file from a web page using this tool: https://www.pdfequips.com/web-to-pdf just paste a url like https://www.pdfequips.com and click convert.

you can also ask the AI to generate a markdown code then copy the code and paste it here: https://www.pdfequips.com/markdown-to-pdf

This is known as 2-up (and more generally, n-up) and there are many tools which can already do it.
