PDF don't upload - Message error


I have tried to upload a PDF file but  “Something went wrong”.

The technical détails are:

What is the problem ?

Thank you.

Hi Samuel,

You might this issue in uploading a PDF file to the online editor if your computer is behind a firewall. 

Please make sure that JavaScript, cookies, Flash and pop-ups are allowed/white-listed for *.prezi.com, *.prezi.com.s3.amazonaws.com and prezi-a.akamaihd.net in your browser and any firewall software, browser privacy add-on, etc. that you may be running on your computer. You can find more about this in our knowledge base:

Hope this helps!

Thank you for your answer Lisa,

Is it possible that this problem appears only with some files and not with another ?
Because when I try with another PDF it works perfectly.

I hope we can resolve that because Prezi can be very usefull for our company.

Kind regards

Hi Samuel!

If you find that this upload works with some PDF files and not others then this means that the file itself may contain some unsupported formatting. Please try “re-printing” it with a virtual printer like pdfcreator: http://www.pdfforge.org/. Or, convert it into a SWF with SWFTools - http://swftools.org/download.html

Or you can convert your PDF to a regular image file with any converter, like this one: https://duckduckgo.com/?q=convert+PDF+pages+to+images.

Hope this helps!


I have re-print the pdf with PDF Creator and I upload successfully the pdf.

Thank you very much for this solution !

Kind regards,
