Dear community,
I have a long lasting frustrating issue for which I would love a bit of help.
Error description
I have an EMF file (graph.emf) that I place in PPTX (graph.pptx) and export to PDF (graph.pdf) using "File => Export => Create PDF/XPS Document".
Problem : The picture schrinks in the PDF.
I have seen the problem in other ressources without final solution : https://learn.microsoft.com/en-us/answers/questions/4905523/pptx-to-pdf-conversion-issues-with-emf-graphics?page=1#answers
Note : the same EMF, in LibreOffice Impress to PDF -> no issue at all.
Information on versions
Version 2509 (Build 19231.20246 Click-To-Run) - Monthly Enterprise Channel
Windows 11 - 25H2 - 26200.7171
Request
Maybe having all the involved files might help understand the underlying problem.

Thank you in advance for your support
That EMF file has problems. If I open it in Inkscape, there is no visible file content at all. If I open it in Adobe Illustrator, the chart is larger than the page size by about the same proportions as the original slide size is to the size in the PDF. In addition, none of the chart text appears in Illustrator.
Perhaps you can use software that exports a more compatible version of EMF, or you can export to a different vector format, like SVG, or a bitmap format, like PNG.
I use EMFs on a regular basis, usually converting Illustrator format to EMF using InkScape, and never see any problems with size changes to the EMFs in PDF exports.
Good morning John,
First of all, thank you for your quick answer. Before going further, the link I gave for picture download cannot be seen (it shows [Moderator note: personal info removed]), still it seems you were able to get the pictures. It is removed automatically?
A bit more of context, I am the editor of the software UniPlot that creates the EMF.
Regarding your comments, when I open the EMF in Windows Paint, it opens properly and the size is correct. I did it in InkScape longtime ago but I do not recall the result, I will check again today.
If you are familiar with EMF+ coding, is there any particular property you would recommend me to check? For example in my last investigation I worked on Units with functions like : SetMapMode(hmf, MM_HIMETRIC);
Regarding using another format, for many different reason my end user really wants to use EMF+ format, so for now I cannot change this.
Also, how come that it works perfectly fine on Linux?
Thank you in advance.
Adrien
I'm not familiar with coding for EMFs, so I can't advise on correcting the issues. I think it's worthwhile testing in InkScape (and Illustrator, if you can afford it). InkScape currently has one of the best EMF imports and exports I've seen available.

Dear @Adrien LAVEAU (External),
Thank you for reaching out to the Microsoft Q&A forum. We are happy to assist you.
This scenario has been observed in similar cases, and the effective next step is to engage the Microsoft Support team to review the backend configuration. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.
The Global Admin can create a support ticket by sign in to the Microsoft 365 Admin Center > Support > Help & Support.
For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.
Note: If you’re an end-user, please coordinate with your Office 365 Global Administrator to handle these steps.
Please accept my apologies for redirecting you to the related team support, as the moderators in this community have limited resources and permission to verify the backend information and to get the quick and better assistance, I requested for this.
In addition, I recommend considering the guidance provided by @John Korchok. Since there are no alternatives for situations where EMF+ is required, his recommendations represent an appreciate approach for your case.
Please let me know if you need further assistance, I'm here to help.
