What Is Secure File Transfer?
Secure file transfer ensures your data is protected while sending files online. BigSendy uses encrypted connections (TLS 1.3) and AES-256 for stored files to keep your sensitive documents safe from unauthorized access, interception, or breaches.
Unlike regular email attachments or basic file sharing services, BigSendy prioritizes security at every step — from upload to download, and during storage.
Best for Business & Personal Use
For Business: Share confidential contracts, financial reports, legal documents, and client data with complete peace of mind.
For Personal: Send private photos, personal identification documents, medical records, or any sensitive files securely.
No matter what you're sending, BigSendy ensures your privacy is never compromised.
No Setup Required
Upload files, share the secure link, and you're done — no software installations, no plugins, no complex configurations. Works instantly on any device with a browser.
Your recipients don't need to sign up either. They just click the link and download securely.
