25MB is the email-shaped cap

Gmail made 25MB the default “small enough to attach” size. Countless HR and school forms copied it even when they are not mail servers.

This page is the generic 25MB tool. If you are definitely sending email, the email landing has Gmail/Outlook-specific notes; the encoder is the same.

25MB has room for a couple of minutes at 1080p. Longer than that, trim or use 50MB.
