When I tried to combine a few PDF files, I get an error " Unsupported file" once I drag the file to combine.

 

I have tried dragging the files I have combined previously, and the same error comes up.

 

I have successfully used this for around 4 months, and just started to have this problem today.

 

Please help, thank you.

Hi Matilda,

 

Like you, I am currently currently experiencing the same issue. I have successfully used this in the past and just started to have this problem today. One workaround I found was to upload the file(s) to your document cloud then combine, rather than selecting the "Combine Files" tool in the document cloud. 

 

  1. Browse to  https://documentcloud.adobe.com/
  2. Select "Upload a File" about halfway down on the web page
  3. Using your file explorer, select the files(s) you want to upload (and eventually merge).
  4. Once they are uploaded, click the square box next to the files
  5. In the tray on the right side of the screen, click combine files.

 

Hopefully that works for you

Hi - I have tried this way as well and it states that some of my documents have "too many pages".

 

Any suggestions how I can overcome this error without reducing the number of pages?

 

Thanks

Hi there

 

We are sorry for the trouble. As described you are getting the error 'Unsupported file' while combining PDFs

 

Is this a behavior with a particular PDF file or with all the PDFs? Please try with different PDF files and check

 

What is the version pof the Adobe Acrobat DC you are using? To check the version go to Help > About Adobe Acrobat DC and make sure you have the latest version 20.009.20067 installed. Go to Help > Check for Updates.

 

Also, please share the screenshot of the error message for a better understanding.

 

Also, please check if the document is secured or not.

 

Let us know how it goes

 

Regards

Amal

I have tried both methods and neither one works, what I found is that some documents are protected and due to that they cant be combined, shame on Adobe by not having a solution for this how ever they sell the products to us, what I have tried is to print prd the secured file and then try the merging button, some times works many of them not ... i think this feature of Adobe needs fine tunning, specially with siegned secured encripted documents.

Hi there

 

We are sorry for the trouble. As described, you are unable to combine the secured PDFs. Once the PDF file is secured by password protection or digitally signed it can not be combined with the other PDFs as it will chnage the document and defeat the purpose of adding security.

 

Hope this information will help

 

Regards

Amal

I sent a pdf file to be signed by a user.

Choose from Tools:  Request Signatures

 

One person was able to sign the document, but the next person I sent it to was stopped by the security.

How can I get anoher signature added?

 

Thanks.

Hi Bob

 

Hope you are doing fine and sorry for the delay in response.

 

Please add all the signers email in the recipient email address box in the order you want the signature to be done so that once the first person will sign the document it will move to the next one and so on. Once the signature process is complete the PDF will be locked for further editing.

 

Regards
