Gmail's attachment limit is 25 MB
25 MB per email, for all the attachments together. Go over and Gmail swaps the file for a Google Drive link, which means it has to upload to your Drive before the email can go.

What happens when it's too big
Gmail doesn't bounce it. When the attachments add up to more than 25 MB, it removes them and adds a Google Drive link to the email instead. The file goes into your Drive, and the email waits until it's uploaded.
The other side has a limit too. Google Workspace accounts accept emails up to 50 or 70 MB, and Google counts that after encoding, which it says adds about 37%. Other providers set their own: Outlook.com and Yahoo send at most 25 MB and iCloud Mail 20 MB.
And if your Google storage is full, Gmail can't send or receive attachments at all.
Gmail's own way round it
Google's answer is Drive. Upload the file to Google Drive and insert it into the email as a link. Drive takes files up to 5 TB, so size is rarely the problem.
The catch is the upload and the space. The whole file has to reach Google before the link works, and it counts against the same storage as your email: 15 GB on a free account, shared with Photos. A 20 GB video won't fit at all.
Drive links follow Drive's sharing settings, so check who can open it before you hit send.
Or skip the upload
With download.fyi there's no upload step. Drop the file, paste the link into your email, and it streams from your browser to theirs the moment they open it. Nothing lands in your Google storage, and there's no size cap.
Your tab has to stay open until they've got it. If they won't get to it today, a pass keeps the file online for 14 days (up to 100 GB, $5) or 30 days (up to 500 GB, $9), paid once.
Questions
Is Gmail's limit 25 MB per file or per email?
Per email. All the attachments in one message have to come to 25 MB or less.
Can I raise Gmail's sending limit?
No. Google Workspace has the same 25 MB limit for attachments you send. Anything bigger goes as a Drive link.
Why did my attachment turn into a Drive link?
Because the attachments came to more than 25 MB. Gmail does it automatically, and the file is stored in your Google Drive.
Does the recipient need a Google account to open a download.fyi link?
No. They open it in any browser. Neither of you signs up for anything.
Other apps' limits
Sign up. Upload. Wait. Just drop it.
No account and no size cap. Your link is ready the moment you pick a file.
