How to upload large files to support

When reporting problems to support or asking questions about a specific functionality, it is always helpful to provide as much information as possible:

  • Profiles or Process Plans when working with pdfToolbox or pdfaPilot
  • Example documents 'before' and 'after' to explain the problem or question
  • Screenshots explaining the specific problem

If such files are larger than 2MB, it is more reliable and faster to send them to us via WeTransfer.

  1. Go to
  2. Click on 'Add files' and select the files that you want to upload (can be one or more).

  3. Enter your email address.

  4. If there is already a support ticket, please enter the relevant ticket number in the 'Message' field so that the files can be easily merged into the appropriate support case.
  5. Your files will be uploaded to the callas software workspace and sent to our support team.

You will receive an email confirming your files were uploaded succesfully.
