Skip the 25MB email limit and the risky public cloud link. Send files up to 5GB with end-to-end encryption, password protection, and links that expire on your schedule.
The tools most people reach for were never built to move big files safely.
Most email providers cap attachments at 20–25MB. A single design file, video, or dataset bounces back before it ever reaches your recipient.
Consumer "share link" features often default to "anyone with the link." One forward, one screenshot, and your large file is exposed indefinitely — with no expiration.
Zipping and splitting large files to squeeze past size limits is slow, error-prone, and strips the fidelity out of video, audio, and design assets.
Every large transfer gets the same zero-trust protection as everything else on CipherSend.
Send a single file up to 5GB on Premium — no splitting, no compression, no quality loss. Free accounts send up to 100MB per file.
Every large file is encrypted with AES-256 and stays encrypted at rest. We never store your file in plaintext.
Set your download link to expire from 1 hour up to 30 days. Once it lapses, the file is unreachable — no lingering public URLs.
Add an optional password to any large-file share. Even if the link is intercepted, the file stays locked.
Drag and drop a file up to 5GB. It is encrypted before it is stored.
Choose an expiration window, a download limit, and an optional password.
CipherSend emails a secure download link directly to your recipient — no account required for them.
Watch downloads in real time and revoke access instantly if anything changes.
Everything you need to know about moving big files safely with CipherSend.
Premium accounts can send a single file up to 5GB. Free accounts can send files up to 100MB each. Files are never compressed, so quality is preserved exactly.
Most email providers reject attachments larger than 20–25MB. Even when a large file does go through, it sits unencrypted in multiple mailboxes indefinitely, with no way to expire or revoke it.
Yes. Every file, regardless of size, is encrypted with AES-256 and stays encrypted at rest. Only someone with the download link — and password, if you set one — can open it.
No. Recipients receive an email with a secure download link and can retrieve the file without creating a CipherSend account.
Yes. Set expiration anywhere from 1 hour up to 30 days on Premium. Once the link expires, the file can no longer be downloaded.
