Hi!
I'm working in an InDesign file where some illustrations are imported from an Illustrator file. This file is linked in the links tab. For some weird reason, the file suddenly says they can't open PDF. But it isn't a PDF it's an Illustrator file. And so I try to place or link my Illustrator file again, but the same pop-up that says can't open this PDF keeps coming up.
Does anybody know what's going on?
Thanks!
Cheers,
Han

If you can place an Illustrator AI file, it must have a PDF fork. InDesign can only use the PDF.
Can you save the file as PDF directly and place this?
But you wrote that you cannot open the PDF. Did you accedently try to open instead of placing/importing the file? This would cause this message.

Hi, I can open the PDF if I make it a PDF, but I don't want to do that. I used to always be able to place an Illustrator file in InDesign so don't understand why it's not working now. It worked Thursday and then on Friday I got the issue. I want to keep it an Illustrator file so I can easily update it.
Thanks for helping tho!

Are you using File>Place?

I tried file > place. I also tried just dropping it in. Both don't work unfortunately.

Make sure to select "Show Import Options" when you place.

Hi,
Thanks for helping. I always do this when placing Illustrator files in InDesign, so unfortunately this didn't work.

InDesign refers to Illustrator files as "PDF", which indeed can be misleading if you're not aware of this.

Hi,
That definitely was misleading me, yes. Good to know!

Illustrator files can be saved without the embedded PDF resource. Those files can only be read by Illustrator. You cannot place them or rasterize them in Photoshop. Try re-saving from Illustrator with Save As and see if the PDF portion was disabled.

Hi,

Hi @han_7184,
I hope the suggestions from the experts helped! Were you able to resolve the issue by ensuring the Illustrator file has an embedded PDF or using File > Place with Show Import Options checked?
If it's fixed, could you confirm the solution here? It’ll be helpful for others facing the same issue. If not, let me know what’s still not working, and we can assist further!
Looking forward to your update.

Hi!
No, I already tried all these suggestions before posting my problem here. Still no idea what is going wrong.

Hi @han_7184,
Thanks for getting back! I tried reproducing the issue on my end, but everything worked fine without errors. Could you confirm the version of InDesign you’re using and your OS details? Also, is this happening only in this particular InDesign file?
Try creating a new InDesign document and placing the same Illustrator file there. Does the error still appear? Also, try placing a different AI file in the same document and see if that works. Let me know what happens, and we’ll do our best to resolve this.
Looking forward to your update.

Hi @Abhishek Rao ,
I'm using Adobe InDesign 2025. When I try to post this Illustrator file in a new InDesign file, I get the same issue. But when I try to place a different Illustrator file in the same InDesign file, I don't get the issue. However, when I tried to make a different Illustrator file, copy pasting the content from the old file, I still get the error. So I think there has to be something going wrong in Illustrator. I'm also using Adobe Illustrator 2025.
Thanks for helping!

Do you save your AI file with PDF compatibility.
Or save as PDF and use that.

Same problem here. I've just updated to 2025, and the import options are for EPS when importing illustrator. Just imports all my artboards as one image.
This is probably one of those clever Adobe things that they do to improve UX and customer experience.

Can you post some screenshots that illustrate the problem, as well as more info regarding the file type you're placing (.ai, .eps etc.) Also, what's your operating system version?

I've worked it out. It seems that now Legacy format Illustrator files are now imported as EPS instead of Illustrator, which is why there is limited functionality in the import options.
Looks like we have to make sure we are paying for that subscription to Illustrator and not using any other software to generate .ai files. Another happy Adobe UX experience.

Good to know you solved the issue. Although it's still hard to know what kind of issue exactly you were dealing with without any kind of additional info regarding your file, the operating system, as well as some other details mentioned previously.

In former times, until 2001, ai files were saved with an EPS fork as it is now with a PDF fork. I strongly recommend to open those files in Illustrator and save them as AIY files with the PDF compatibility according to the current version.
But take care, as you might run into font problems Either, the used fonts are not available on your computer or T1 fonts are used. In both cases you must them replace with fonts which can be embedded into PDDs.

Ashley, your comment is intriguing: what other software are you using to make .ai files?

Hi Mike. I use Rhino3d to make architectural/design drawings. Sometimes export them as .ai, then in Illustrator duplicate the artboard a few times, add annotations etc. to each. Then drop them into InDesign where I have the page templates and the rest of the presentation content. Limiting the way that InDesign handles legacy .ai files seems unnecessary and was a hassle to solve.
I can only remember 2 occasions in the last 10 years where updating a piece of Adobe software brought a benefit rather than pain.

I'm still not sure what you mean by "legacy .ai files". Does Rhino3d create what you call "legacy .ai files"? Plus, you're saying that you open them in Illustrator and resave from there anyway. So how is your final file any different from a regular .ai file then?

I was not aware that any other software could make .ai files. I will have to learn more about that.
At the very least, I would wash those Rhino3D files thru a SaveAs in Illustrator, saving them with PDF compatibility, before placing into InDesign.
Further, can you avoid using anything EPS? That filetype is long deprecated.
