Preview (like most Mac apps) can print to PDFs, and even has a shortcut for this functionality via a menu option Export as PDF.... I have a scanned document in .tiff format that I'd like to convert to a PDF, but using the option above yields a PDF with large margins around the image file. Is there a reason why this is happening? More importantly, is there a way to suppress these margins?

I know of a website that people have used that is supposed to be very good (there is no software to download) and everything is carried out online. It is called FillAnyPDF:

which includes digital signature. I have never used it myself, but it may turn out to be what you are looking for, but it might just be for form filling.
Alternatively Wondershares PDF Editor for Mac maybe cheaper than Adobe:

I left another suggestion in the comments below however this article by OSXDaily (particularly the comments section) should provide more insight to your needs:
Instead of Save As... PDF, Print->"Save as PDF". You can get around the print margins by setting up a printer/presentation that has no margins, "full bleed".
A few important steps:
First, go to File -> Page Setup and make sure that you've got the dimensions there identical for the default paper size in the printer. In my case, it's 8.5 x 11 inches for Letter size paper. Read the dialog box carefully, and select the option that lets you set a size larger than the printer will allow.
In the print dialog, make sure you do NOT have "scale to fit paper" checked.
You should now see that the print preview in the print dialog is edge to edge.

If you don't want any borders, create a custom paper size and change margin size to 0 as shown below:
Name your custom paper size, use it and create PDF.
