DOCX (recommended)
One major advantage with dflow is that you can upload your Word documents (.docx), edit them in Word Online and let dflow automatically convert them to pdfs when they are ready to be signed.
You may also upload pdfs, but there are some limitations you need to be aware of. It is not possible to send PDFs:
you cannot open yourself
that are password-protected or contain password-protected fields
that are over 5 MB
that are digitally signed already
If you believe that none of the above errors apply to the PDF you are trying to send, please contact us in the chat.
