About Blink
Last updated: August 2026
What is Blink?
Blink is a privacy-first ephemeral file sharing service. Share files, images, videos, and audio through a secure link that self-destructs after a timer you choose. Available on the web and as an Android app. No accounts. No tracking. No permanent traces.
How It Works
- Encrypt on your device - Your file is encrypted with AES-256 before it ever leaves your phone. Your private key stays with you - not even we can read your data.
- Share instantly - A unique secure link is created for each transfer. Share it anywhere - by text, WhatsApp, email, or QR code. Only the receiver with the key can decrypt and view the content.
- Vanish automatically - The file is permanently deleted from our servers when the timer expires. No backups, no archives, no recovery.
Key Features
- End-to-End Encrypted - AES-256 encryption happens on your device before upload. Servers only ever see encrypted ciphertext.
- Any File Type - Share any file type up to 100MB per batch in the Android app (5MB on the web).
- Auto-Vanish Timer - Choose 1 to 10 minutes (5 is the default). When time is up, the file and every copy are gone forever.
- No Account Required - No sign-ups, no emails, no personal data. Just open and share.
- Daily MB Quota - Enjoy a free daily transfer quota, and watch a short ad to instantly get more when you need it.
- Lightning Fast - Powered by Cloudflare's global edge network for low-latency uploads and downloads from anywhere.
Our Privacy Promise
Blink is built around one idea: your data should not live forever. Files are encrypted on your device, keys never leave your hands, and everything is permanently erased when the timer expires. We do not create accounts, we do not collect personal information, and we cannot recover your files - by design.
