Hello @zebedee4321,
I hope you are doing well, and thanks for reaching out. We're sorry for the trouble you had.
Could you please share more details about the issue?
Are you converting an image file, such as JPG/PNG/HEIC/TIFF, or are you converting a PowerPoint file to PDF?
On the Mac, are you using PowerPoint's Acrobat ribbon/add-in, Acrobat desktop > File > Create > PDF from file, or Acrobat on the web?
What are your Acrobat version/build, macOS version, and PowerPoint version?
For the Acrobat online converter, in Acrobat on the web, go to Convert > Convert to PDF, choose the appropriate conversion tool, select the file, and continue; the file is converted and saved to Adobe Cloud storage. Please note that Acrobat preserves the original image quality and dimensions during default JPG-to-PDF conversion unless compression is requested. So if the PDF is visibly lower quality than the original image and you did not use a compression step, I’d suggest testing the same file in the desktop app and checking the quality.
If you have Acrobat Pro and need control over image compression/downsampling after the PDF is created, use PDF Optimizer:
Open the PDF in Acrobat Pro.
Choose File > Save as Other > Optimized PDF on macOS.
In the Optimized PDF dialog, adjust the relevant panels, especially Images
Please check these articles and try the suggestions, and let us know how it goes: https://adobe.ly/4wRlGBE
