200 times the Gmail limit
TransferNow’s free tier absorbs everything email rejects: 5 GB per transfer, no sign-up, no credit card.
25 MB is the exact limit for Gmail attachments — and the reason behind the “file too large” message. TransferNow sends up to 5 GB for free, 200 times more, with no sign-up: your recipient simply gets a download link.

The problem
Gmail’s 25 MB cap (20 MB for Outlook) dates back to a time when a photo weighed 500 KB. Today, a single phone video, a presentation with images or a scanned file exceeds it — and the recipient’s mailbox can reject the message even when yours accepts it.
Worse: attachments are encoded before sending, which inflates their size by about a third. Your 20 MB file actually takes up ~27 MB in the message — that’s often where the baffling rejection comes from.
Logarithmic scale — the exact values are what counts.
The solutions
The problem is as old as email itself, but the solutions don’t all cost the same. An honest comparison.
| Method | Max size | Quality | For the recipient |
|---|---|---|---|
| TransferNow (dedicated transfer)Recommended | 5 GB free · 500 GB with an account | Files intact, no compression | One click, no account |
| Compress to ZIP | 10 to 30% savings at best | Intact | Not enough once media is involved |
| Google Drive auto-suggested by Gmail | Depends on quota (15 GB shared) | Intact | Access rights to manage, quota used up |
| Drive / cloud storage | Depends on the account quota | Intact | Account or access rights often required |
Above 25 MB, a download link replaces the attachment: your message stays light, the recipient clicks and grabs the files — up to 5 GB for free, with no account on either side.
Compressing office documents can sometimes squeeze a borderline send through. But photos, videos and scanned PDFs are already compressed: ZIP gains you next to nothing.
Gmail automatically shifts large attachments to Drive — eating into your shared 15 GB and adding access rights to manage. For a one-off send, a transfer link is cleaner.
Dropping the file into online storage works, at the cost of an account, permissions and a link that never expires on its own. A time-limited transfer is a better fit for handing files over.
Guide
The 48 MB PowerPoint goes as is: no compression, no splitting, no account to create.
TransferNow sends the message for you — or you paste the link into your own email, which now weighs just a few bytes.
Download straight from the browser, no sign-up. You’re notified as soon as the file is picked up.
With TransferNow
TransferNow’s free tier absorbs everything email rejects: 5 GB per transfer, no sign-up, no credit card.
The message you send only carries a link: no clogged mailbox on the recipient’s side, no silent server-side rejection.
Files are scanned by an antivirus engine before the link becomes active — more reassuring than an attachment.
The link stays active for up to 7 days for free — and up to 365 days with an account.
Attachment encoding adds about a third to the real size: a 20 MB file takes up ~27 MB in the message, above the 25 MB limit. And the recipient’s mailbox may have an even lower cap.
Create a TransferNow transfer (free up to 5 GB, no sign-up) and send the link by email: the message always goes through, whatever the files weigh.
No: they click the link and download from their browser, no sign-up required. You’re notified of the download.
TransferNow plans go up to 500 GB per transfer, with availability configurable up to 365 days.
Yes: a 45 MP full-frame RAW weighs 45.4 MB according to Canon’s manual (EOS R5) — nearly double the limit, before encoding even kicks in. The same camera’s high-quality JPEG (≈ 13.5 MB) fits, but two are enough to max out the message.
