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 10MB, and we recommend having max. size of 7,5MB, as processing of the document can increase the size to 25% larger.
When using copy recipients, the size of all files in the final e-mail must not exceed 7,5MB, otherwise they cannot be delivered to the recipient.
