Frequently asked questions
Why is my PDF still rejected after compression?
The portal may also enforce page count, encryption, filename, paper size, PDF version, or unpublished rules. Uploadable only confirms rules it can observe and that you entered.
Does Ready to upload guarantee acceptance?
No. It confirms the technical rules entered and checked by Uploadable. The destination may apply additional unpublished requirements.
