100% Private · No Signup Required
Send large files securely without creating an account. Your files are encrypted in transit, accessible only via your unique link, and automatically deleted after 24 hours. We cannot browse or publicly list your uploads.
Privacy promise
Big File Sharing is a temporary transfer tool — not a cloud storage platform. We do not browse, index, or publicly list your uploads. Files exist only for the brief window you need them.
What we don't do
Three simple steps. No accounts. No public gallery. Just secure, temporary file transfer.
Drag and drop any file type. No registration required.
Copy the unique URL and send it to your recipient only.
Files are permanently removed after 24 hours by default.
Every design decision prioritizes your privacy, AdSense policy compliance, and a distraction-free transfer experience.
There is no browseable file library. Your upload is never listed on our site or indexed for public search.
Files Auto-delete after 24 hours (configurable in admin). We are a transfer tool, not long-term storage.
Skip signups entirely. Upload, share, done. Less data collected means less risk for you.
All uploads and downloads use TLS encryption. Your files travel securely between you and our servers.
Each file gets a cryptographically random link. Without the URL, nobody can access your upload.
Convert, resize, and process files with our browser-based utilities — all documented and privacy-focused.
