Adjusting Thickness of Multiple Horizontal Lines

[Joshua23155736fmzf]

I have a PDF for which I need to make the thickness of dozens of horizontal lines uniform. I have attached one page of the PDF to this post. Currently, the only way I know to do this is to zoom in on each line individually and drag it until it is the correct thickness, which is very time consuming. Is there a better way to do this? I have Office 365 and Adobe version 22.3.20322.0. 

I've looked up ways to do this and found a few ways, none of which have worked for me. One is to right click on the horizontal lines and select 'Properties' and change the thickness, but when I click on the horizontal lines, 'Properties' is not one of the options for me. Another method I found was to use the Find and Replace to adjust the Properties of the horizontal lines, but when I search for "Horizontal Line" in the "Find" box, it doesn't return any matches.

Your sample pdf is showing 3 types of lines, the first two lines are actually rectangles, about 1pt. in size, most other lines are actual lines (strokes), the last 3 lines are type (fonts). One option would be to re-do the document in Word so all the lines are consistent, you would not need to re-do the form fields, as you can do a file> replace (Tools> Organize pages> Replace), using the updated pdf as the new file, that would preserve the original form fields. Another option would be to go to Tools> Print Production> Fix Hairlines (make them 1pt.). This would only effect the strokes, so the font lines would not change. There is also a preflight profile that works pretty much the same as Fix Hairlines. Another option would be to place the pdf into InDesign where you could replace all of the existing lines, delete the original lines in Acrobat, update the InDesign link, export to a new pdf.

I should also mention that different types of lines may appear to be different sizes, even if the sizes are the same, depending on pdf viewer and preferences.

Thank you Luke. I am using your first suggestion. I converted the PDF into a Word document and then was clicking on each line individually and then going to Draw and then clicking on Thickness and selecting 3/4. However, the Thickness button has disappeared. Any ideas on how to get it back? I restarted my computer but that didn't fix it. Also, is there a way to select multiple lines simultaneously? I am on a PC.

It might be better to start with the original Word file, if you have it, as converting from one software to another is almost never a perfect trip. I don't use Word very often, so I can't help you there.

That's not really an option. I spent 12+ hours reformatting the PDF so the original word document is totally out of date.
