Problem with Saving PDF file with transparent background

[B3cold]

Hello. I'm kinda new to PS and trying to help my with my friend logo. I'm trying to make a PDF with Transparent background. 

What have I tried? I tried to follow this thread. I've saw a thread in here but I'm not sure if all work?

• Save As > Photoshop PDF
• High Quality Print.joboptions 
• Change compatibility to Acrobat 6 or higher (this will trigger "modified")
• In the Compression tab, uncheck "Convert 16 Bit/Channel Image to 8 Bits/Channel"

When I open the PDF (it's open in google chrome), it still shows a White background, is that normal? If so, where can I check if it's really transparent? Thank you for your answer.

Hi simply save it as a png logo with transparent background that can help you or you can use psd file for printing...regards

But I need it to be a PDF file, does it works the same? My friend needs that logo to be printable for his working clothing. So he said, It needs to be a PDF file.
