The problem
Why are ZIPs email’s least favorite files?
The archive stacks two problems: the weight — you zip precisely because there’s a lot to send, so you quickly blow past the 20-25 MB attachment limit — and the distrust of email services: many block or quarantine archives, especially when they contain executables.
And re-compressing saves nothing: photos, videos and XLSX files are already compressed, so the ZIP barely shrinks them. Splitting into volumes (z01, z02…) forces a painful reassembly on the recipient, and the drive adds an account and permissions.
The simplest route: send the archive as is through a dedicated transfer, scanned by antivirus on arrival. That’s what TransferNow does, free up to 5 GB.

The solutions
Four ways to send a large archive
The goal: the archive arrives whole, with no security alert and no gymnastics on the recipient’s side. An honest comparison.
| Method | Max size | Quality | For the recipient |
|---|---|---|---|
| TransferNow (dedicated transfer)Recommended | 5 GB free · 500 GB with an account | Archive intact, scanned by antivirus | One click, no account |
| Email attachment | 20-25 MB | Intact | Often blocked or quarantined |
| Split into volumes (z01, z02…) | 20-25 MB per message | Intact if every volume arrives | Manual, fragile reassembly |
| Drive / cloud storage | Depends on the account quota | Intact | Account or permissions often required |
The dedicated transfer: the archive gets through, period
No attachment filter, no 25 MB cap: the ZIP leaves as is, up to 5 GB for free. The antivirus scan before the link goes live lifts the recipient’s legitimate wariness of archives.
The attachment: quarantine guaranteed
Even under the size limit, archives trigger the security filters of corporate email — with good reason. Your legitimate ZIP ends up in quarantine and nobody gets told.
Split volumes: the missing piece
Multi-volume archives date back to the floppy disk era: if a single piece is missing or lands in spam, the entire archive is unusable. Avoid it whenever a modern transfer is possible.
The cloud: possible, less direct
Dropping the ZIP on a drive works, at the cost of occupied quota and permissions to manage. For a one-off delivery, a direct link with no account is simpler on both ends.

With TransferNow
Built for your ZIP files
No blocking
No email filter
The recipient gets a link, not an attachment: no quarantine, no silent rejection, even for archives containing legitimate executables.
Antivirus
Scanned before it goes live
Every file is scanned by an antivirus solution before the link becomes active — the recipient opens the archive with confidence.
Integrity
The archive arrives whole
Byte-for-byte transfer: no missing volume, no CRC error. What you compressed is what unpacks on arrival.
Folder as is
What if you didn’t zip at all?
TransferNow accepts entire folders: drag the folder in as is, structure preserved — the compression step often becomes unnecessary.
Password
Double protection possible
A password on the transfer (on top of your archive’s own, if it has one) and an availability window you control, up to 365 days with an account.

Frequently asked questions
Why is my ZIP blocked by Gmail or Outlook?
Email services filter archives for security, especially when they contain executables — on top of the size limit (20-25 MB). A transfer link sidesteps both problems: no attachment, so no filter.
How large a ZIP can I send for free?
Up to 5 GB per transfer, with no sign-up. With an account, up to 500 GB per transfer.
Is the archive scanned for viruses?
Yes: before the download link is made available, files are scanned by an antivirus solution. Your recipient is reassured — and so are you.
Do I really need to zip before sending?
Often not: TransferNow accepts entire folders and preserves their structure. The ZIP remains useful to freeze a deliverable into a single file, but it’s no longer needed to "get the send through".
Do 7z and RAR go through too?
Yes, every archive format travels as is: ZIP, 7z, RAR, TAR.GZ… None is rejected or modified.
