| Gmail, personal account | 25 MB of attachments in one email. Gmail sends bigger files as a Google Drive link instead. |
|---|---|
| Outlook for Windows, internet email account (POP3 or IMAP) | 20 MB (20,480 KB) in one email, by default |
| Outlook with a work (Exchange) mailbox | 10 MB (10,240 KB) by default. The administrator can change it. |
| The PDF you download | 20,000,000 bytes or less, so both counts accept it. Windows shows it as 19.1 MB or less. |

Email programs refuse attachments over a set size. Google says the limit for personal Gmail accounts is 25 MB. Microsoft's Outlook help says 20 MB for internet email accounts such as Outlook.com or Gmail, and 10 MB by default for work (Exchange) accounts, and it counts the message together with the attachment. Limits change, so check the current help page for your account.
This page opens the PDF tool with 20 MB filled in, which suits most personal email. Change the number to match your own limit, and aim a little under it, because the message counts too. If your mail program still refuses the file, type a smaller number, such as 15 MB, and try again.
