hyperlinks not working when downloading PDF from email

[Olivia34270948xwmz]

So I am using Illustrator and I have a couple of hyperlinks in the document. I made them transparent, so the layout looks nicer. The links work when I save it as a copy to a PDF from Illustrator and then I attach it to an email and it works when you open the document from the email. But when the PDF is downloaded from the email, some of the hyperlinks don't click, and some parts of the URL change. Any advice on how to fix this? Thank you!

WHich application are you using to open the PDF? It needs to support links.

I send it on Gmail and then download it on Mac and it opens with Prewiew

If you open it directly in Preview, does it then work?

If I open the pdf just downloaded from Illustrator in Preview it works just fine. When I attach it to Gmail it works when you open it from the email, but when you download it from the email and open the pdf then some of the links don't work or they change.

That is then nothing that Illustrator has anything to do with.
