Certain pdf images don't display after Ventura upgrade.

Since upgrading to 13.2.1 images are not displayed in certain pdf files. Files that appeared OK before upgrading now have just empty boxes where the images should be. The same files hosted on a website and viewed via a browser appear perfectly (Safari, Firefox and Chrome). However, if the files are downloaded and viewed in Preview or PDFExpert the images are missing (this is true for the original of these files as well, not just downloaded ones). Bizarrely, the files view correctly in Safari on MacOS but not in Safari on IOS (iphone and ipad), they also appear correctly on Android Internet browser.

Here is an example

Any thoughts??

Well on MacOS 13.2.1 —looking at the PDF in Safari browser no image.

Firefox browser yes images

Downloaded to Desktop>Preview images yes.

You can try a different browsers a different PDF editor and compare your reuslts.

My best advice—I would use what works.

Interesting, I was typing my reply so didn't see this come through. So it's been a problem for a while on MacOs and IOS but with no resolution.

The images are fine in Preview 11.0 downloaded in Catalina. Interesting since the Preview version in Catalina, Monterey & Ventura are the same.

The problem is really with the files being hosted on a website and visitors who want to view the files using an iPhone, iPad or Ventura report that the images are missing.

I have isolated the problem to being relatively old pdfs that were generated for print and so have CYMK-based jpeg images.

'The example on my dev server is a relatively small file so I can probably extract the images and resave them and then regenerate the pdf. However, I have a number of much larger files with many images so this is very frustrating.

Very interesting.

Yes cross platform compatibility has always been where you earn your money in dev....

Here you can include cross browser, cross application compatibility; it's always something.

good computing

I hope Apple pick this up and do something, as it potentially affects lots of pdfs containing images originally created for physical printing using CMYK.

Feel free to send Apple feedback.

Feedback - macOS - Apple

Looks like this problem has been around on IOS for a while but is new on Ventura:

Actually I see the same problem in Monterey.

Just to add, the images do appear in Adobe Acrobat Reader in Ventura when the PDF is downloaded.

Works for me as well running Ventura

Does not work for me running Ventura.

I guess. I haven't checked anything earlier than Monterey.

FWIW, The images are visible with Preview in Big Sur as well. I guess something broke starting with Monterey.
