Frequently asked questions
How accurate is the size limit?
Pages are added one at a time and a new file starts whenever the next page would exceed the limit. Single oversized pages will produce a single oversize file.
How do I get all the parts?
Each part downloads automatically as it's ready. Use "Download all" to re-trigger any you missed.
