• You cannot use DocuWorks Trial edition.
You can open High-compression PDF files with Adobe Acrobat 4.0 (PDF 1.3) or later.
The Image Compression feature may not be able to scan the colors of the documents
precisely due to the image processing to improve the compression ratio.
Signature using the electronic stamp of DocuWorks is not supported.
Acrobat Approval is not supported.
PKI (Public Key Infrastructure) encryption of PDF is not available. A certificate is not used
