How do I merge two documents together

I need to combine all of my documents together and I'm not sure how to do that. Also, when I try to create a new form by uploading a pdf it says there is a 15 page limit, but I've uploaded more than 15 pages before. 

Hello! Please find answers to your queries below:

- I need to combine all of my documents together and I'm not sure how to do that.

I believe that you are referring to combine the generated PDF responses. If yes, then please note that with JotForm you have the option to download single filled-in PDF for every response. You'll need to use other options available online and offline to combine/merge these PDFs into one.

This is Adobe's guide to merge multiple PDFs into one: https://helpx.adobe.com/in/acrobat/how-to/combine-files-into-pdf.html?set=acrobat--fundamentals--edit-pdf

If you're referring to something else, then please elaborate.

There has always been a limit of 15 pages for the PDF Form Converter and the only way to resolve this problem is to reduce the number of pages.

I hope this helps. For further queries, feel free to write back to us.

Thank you!
