Frequently Asked Questions
Why do email servers reject videos close to 25MB?
Email protocols convert binary attachments into Base64 ASCII text, which increases file size by roughly 33%. A 20MB video expands to ~26.6MB in transit and gets bounced. TargetCompress factors in this overhead automatically.
