Can User Guides in PDF format on The Document Foundation website that I downloaded be transferred to my Kindle Reading app?

I have the Amazon Send To Kindle app on my PC & my downloaded LibreOffice Calc Guide, Writer Guide & LibreOffice Getting Started Guide on the USB flash drive attached to my PC. I would like to ask Libre Office permission use the dragndrop feature in my Amazon Send to Kindle app to transfer these Libre Office Guides in PDF format on my USB flash drive to my Kindle Reading app. If NOT, could I download a separate copy of Libre Office Calc 7Guide in PDF format to my smartphone’s Send To Kindle App?
