Qt pdf reader

[mrdebug]

Hi, I need to extract the pages from a pdf document and store them in png files.
Can someone suggest me the easy way to do this?
Which is the most easy, free and portable library (Windows, Linux, mac) to use?

You can use QtPdf, it's an official module now.

Other popular library is poppler.

sadly not free, but a ridiculous 50$ a year.

But it has free option: under GPL.

@sierdzio you're right!

the marketplace also has a description on how to build it 🤔
It's part of the source code of qtwebengine oO

Many thanks for the replies.
After a first check, poppler seems to be not so fast to build in Windows, Mac, Linux.
An already builded version for Windows exists but it is not updated.
I don't want to buy the non free library because I need to manage pdf in a non commercial software.
The only thing that I need is to extract from the pdf each page as png image.
Is there somethin else as free library?

It seems it has another free option: LGPL

Licenses:

GPLv2

LGPLv3

How many times are you going to build/rebuild the library?
I expect once per OS, so is that build time a big deal?
Once you're done, you'll use your own binaries
