Hello and thank you for reaching out!
First, may I ask how you’re using Collabora, is it for an organization, a company, or perhaps part of a larger integration?
Now, regarding your issue: we understand how frustrating it can be when landscape-oriented pages in PDF files aren’t displayed properly in Collabora. You’re right — while Collabora offers full support for Word documents, PDF handling is more limited and primarily focused on viewing, not editing.
If this is a critical part of your workflow or time-sensitive, we’d strongly recommend contacting our support team would be the best option for a quicker resolution.
Alternatively, if it’s not urgent, you’re welcome to open a GitHub issue describing the problem in detail (with a sample file if possible). You can file the issue here:
https://github.com/CollaboraOnline/online/issues
We’ll add it to our backlog and prioritize it based on available resources and community impact.
If you or your team have a technical background and would like to contribute a fix or improvement, we’d be more than happy to help guide you! You can check out our contributor guide here:

Thanks again for sharing your feedback
Cheers,
