Publish a Webcomic on Multiple Platforms FAQ
Production answers without the guesswork
Should every platform receive identical files?+
Keep one high-quality master, then derive destination files only where current official requirements require a change.
How often should I verify requirements?+
Check the linked official source and live upload dashboard for every release because platform rules can change without notice.
What does manual review mean?+
It means the cited official public page does not expose a fixed value, so the tool refuses to assume one.
