    Hello ​@Southdude 

     

    I hope you are doing well, and thanks for reaching out.

     

    Could you please share more details about your issue? 

    The suggestion to save as PDF is to recreate the PDF file with a different file name.

    Here’s how it works in Acrobat instead:

    • Menu > Save > Saves your changes to the same PDF
    • File > Save As > lets you save a copy of the same PDF (new name or location)

    So, in this case, if the goal was to re-save or refresh the file:

    • Use Save to overwrite the existing PDF, or
    • Use Save As to create a duplicate PDF

     

    We’re here to help, just need more info.

    Regards,

    Anand Sri.

    Hi there

     

    Hope you are doing well and sorry for the trouble. 

     

    Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. Also try requesting signatures via Adobe Document cloud here https://adobe.ly/3LJShXe and check.

     

    The “unsupported file type” message usually appears if the file you’re trying to send for signature isn’t in a supported format. Adobe Acrobat Sign supports PDF files, so please make sure your document is saved as a PDF before uploading.

     

    If it’s already a PDF, try the following:

    • Open the file in Acrobat and choose File > Save as PDF (this can help reformat the file if it was converted from another format).

    • Ensure the file isn’t encrypted, password-protected, or contains dynamic XFA forms.

    • Check that the file size doesn’t exceed the upload limit (usually 10 MB for Sign).

    Once done, try sending it again and see if that works. 

     

    Let us know how it goes.

     

    ~Amal
