1. Re: Which PDF Optimizer options are necessary to preserve hyperlinks?
It seems there is a long standing bug that flattening transparency does this. (But only if it actually has transparency to flatten). Flattening is mandatory to save as PDF 1.3.

2. Re: Which PDF Optimizer options are necessary to preserve hyperlinks?
Thanks for the info, useful to know - though I was also hoping for those options that by design remove hyperlinks.
So my latest run (working with a huge file here so not easy to test) had everything ticked except (on Discard Objects) "Discard all JavaScript actions" and "Discard document tags" and (on Discard User Data) "Discard all comments, forms and multimedia", "Discard all object data" and "Discard external cross-references".
If anyone already knows, it'd be great to know which of the above five will remove hyperlinks and which will preserve hyperlinks if ticked.

3. Re: Which PDF Optimizer options are necessary to preserve hyperlinks?
Some software will use named destinations to implement their hyperlinks, so that can be relevant. Others will use JavaScript. Others will use neither. So the type of hyperlink is relevant.

4. Re: Which PDF Optimizer options are necessary to preserve hyperlinks?
Ah, okay, didn't know that. This is for hyperlinks in documents exported from inDesign (CS6).

5. Re: Which PDF Optimizer options are necessary to preserve hyperlinks?
Does nobody know which are the settings that remove hyperlinks?
I'm currently stuck doing blind trial and error, and the results seem inconsistent, which makes me think there's something to do with combinations. Maybe, if the hyperlinks end up implemented one way, certain settings remove them or switch the way they are implemented, and if they end up implemented another way, other different settings remove them.
Any clues on how to discover which flavour of hyperlinks a document uses would also be very helpful - how to know if any given hyperlink is a 'named destination' hyperlink or a javascript hyperlink.
(Seems like "Discard all comments, forms and multimedia" is one of the ones that might need to be unticked)
-------
Incase any people enjoy giving the RTFM treatment, I'll pre-emptively point out that the manual is very unhelpful here. It just re-states the titles of each option as a sentence, with no additional information.
For example:
- Discard All Comments, Forms And Multimedia
- Removes all comments, forms, form fields, and multimedia from the PDF.

6. Re: Which PDF Optimizer options are necessary to preserve hyperlinks?
Yes, absolutely. Hyperlinks are implemented in different ways. You can look at them in Acrobat to find how they are done. And InDesign is likely to vary what it does. So, if there is a JavaScript hyperlink, and you remove JavaScript you are demanding that the link be broken. Many links will use form features so that option is relevant. What you see as a hyperlink could readily actually be a fill-in form!
You need to understand your links to get anywhere with this.

7. Re: Which PDF Optimizer options are necessary to preserve hyperlinks?
Thanks - but how in Acrobat do I look at them to find out how they are done? I'm guessing it's one of the 'Tools' but they seem to be all specific to one thing, so I'd need to know or have an idea of what the link was to know which tool to use on it.
