I am trying to convert a PDF file using the PDF24 PDF to PPTX tool, but I am having difficulties uploading my file to the online service. Every time I try to upload my PDF file, I encounter technical problems or the website no longer responds. In addition, it seems that the tool does not accept the size of my PDF file, even though it should be able to handle different file sizes according to its description. Despite several attempts and checking my internet connection, I am unable to upload my file. This problem prevents me from using the tool as intended for the conversion of my files.

The difficulties you describe may be due to temporary technical problems with the website or due to server overload. Try again at a later time. Also, make sure that your PDF file is not being uploaded from an account that may have restrictions. If the problem persists, it could be that your file has a special format that the tool does not support. Try converting your file to a more common version of PDF. If that still doesn't work, contact support for a more detailed error analysis.
