PDF Software tool needed

Hi,

I work very often with all kind of PDF-Files and i am looking for a FREE Portable PDF-Tool to do the following tasks:

1. Split and Merge PDF-files
2. Extract images from PDF-files to JPG-format
3. Convert JPG-Images to PDF-format

I do not want to use: Foxit-Pdf reader, because that program is to Big for my system
I prefer an offline standalone version

Has anobody any suggestion?
Thanks

PDF Shaper Free (not portable).

I would recommend PDF24 Creator - no charge or installation required.

Regarding PDF24, I tried 'PDF24 Toolbox' 18 months ago and found issues with it. See file.

Maybe updates have changed how it works since then but I hope the file helps.
