You can only upload PDF files to Penneo.
Text files can be exported from your word processor in PDF-A compatible format. This format is recommended for long-term storage of digital documents (ISO 19005-1 compliant).
Files must not exceed 20 MB, and we recommend having a max size of 15 MB, as processing of the document can increase the size of the files by 25%.
When using copy recipients, the size of all files in the final e-mail must not exceed 7,5 MB, otherwise they cannot be delivered to the recipient.
