Questions
What does Free include?
The in-browser tools, uncounted and with no account, plus 10 server conversions a day, up to 100 MB a file.
Does Pro have any limit at all?
Pro removes the Free limit of 10 server conversions a day and takes files up to 2 GB. One safeguard applies to everyone, Pro included: at most 20 server conversions every 10 minutes from one network, which stops automated floods. Converting a folder of ten files, then another ten, stays inside it.
