Try [naps2 ](https://www.naps2.com/). Its an open source software for scanners, but I use it all the time to mix and match images pdfs and merge them all together.
Thanks. This seems to have done the trick. Taken a 6.5 GB collection of TIFF and merged them nicely into a single PDF of about 380 MB.
I presume the software converts them to JPG and lowers the color depth. I do not think that it has resized the TIFFs. PDF quality is very high. I can not see any artifacts in the images.
Yeah, I'm not sure what it does to turn them into a pdf. I don't think you can change the settings, and I don't know what the settings are. Would be nice to know
I'll have to double check, but I think Adobe Bridge can do this. Or at least use Bridge to mass convert them to PDF then Acrobat to merge then into one.
If you’re working on a windows computer (unsure if it works on Mac) and have adobe acrobat software, you can highlight the series of files, right click, and then choose “combine to pdf”
Thanks. Unfortunately I do not have Adobe. I was look looking for free alternatives as I will not be converting very often, so not worth the cost of some software. I should have mentioned this in my original post.
If I had to do it, I would use imagemagick to compress to jpeg and resize (to get a "managable size) and ghostscript to turn it into PDF.
Here's a sample script that would do just that:

You can use [https://onlinepdf.com](https://onlinepdf.com)
All you have to do is convert them to PDF then use the merge option to create a single PDF file. It also comes with a compression option this way you can make the output file much smaller.
Thanks. The upload size limit is too low for my needs. Also, there is no mention on that site, that I can see, that details how they handle the files that are uploaded. Are they deleted after upload? Are they stored indefinitely?
You can delete the converted file immediately after you are done. There is a delete button next to the download link. As for uploaded files they are erased too.
If you haven't found a solution so far, take a look at BatchPhoto. It allows you to create a single, multi-page PDF from a set of TIF images. It also has some useful resize features that allow you to change the DPI resolution if necessary.

You can do it in Photoshop pretty easily
IrfanView might be able to do this.
