Hi Delightful_thinking9504,
Thank you for reaching out.
Could you please share more information on what you are trying here? Are you trying to convert files to PDF using the Acrobat web account?
Would like to inform you that there is a limitation when trying premium tools on Acrobat web. If you don't sign in to Acrobat web or Acrobat browser extensions with an Adobe ID, you can only complete one free transaction and download the resulting file one time. When trying premium tools, you can make one free transaction every 30 days on a rolling basis. For more information, please refer to the information under the “How many times can I use the free tools?” on the following page: FAQ | Try Adobe Acrobat online services.
Let us know if you have any questions.
Thanks,
Meenakshi
