Can't find link option in Preview under annotation

You can add link annotations with Adobe Acrobat DC Pro if you have that, or as an example, PDFPen, or PDFpen Pro from the Mac App Store. There are no included tools with macOS that will link annotate your existing PDF.

Hi, I am having a similar problem but my PDF came from photoshop and I need to add links to it. It's not something I do often so I didn't even notice that the link annotation had been removed. Any advice?

The link annotation has been gone from Preview for years. A properly set URL link in a Pages v5.5.3 document will survive and function after an Export to PDF.

1. In Pages, select the text to receive the link
2. Right-click on this selected text and choose Add Link
3. Type in the full URL of the link, and press return to set it.
4. Click outside of the Link dialog in your document (the dialog will close)
5. Export your Pages content to PDF.

Well, I am the one that said Pages v5.5.3. But, it does not export blue hyperlinks, or blue text, by default. Pages '09 v4.3 does export hyperlinks as blue text with blue underlines by default. Thus, the steps that I provided above for Pages v5.5.3, would be different using the Link Inspector in Pages '09.

Pages '09 v4.3

1. Select the text to receive the link
2. Open the Link Inspector, and check Enable as a hyperlink
   1. Set Link To selection as webpage, email, or bookmark (Links to other Pages documents do not export to PDF, or Word)
   2. Type in the URL and press return to set it
   3. Export to PDF as usual
