Instant File Sharing,
No Sign-Up Required

SendMaster lets you send any file to anyone in seconds. Upload, share a link, done. Files disappear automatically after 24 hours — no clutter, no accounts, no cost.

What SendMaster Can Do

☁️

Cloud Upload & Share

Upload any file up to 1 GB. Get an instant shareable link and QR code. Recipients download directly — no account needed on either end.

⚡️

LAN P2P Transfer

On the same Wi-Fi network? Send files directly between devices at full local speed using WebRTC — the data never touches our servers.

📱

Works on Any Device

Runs entirely in the browser. No app to install. Works on phones, tablets, laptops, and desktops — iOS, Android, Windows, macOS, Linux.

📦

Installable PWA

Add SendMaster to your home screen or desktop for a native app-like experience. Works offline for the app shell after the first visit.

⏰

Auto-Expiry

Files are automatically deleted after 24 hours. No manual cleanup needed. Share without worrying about what you leave behind.

🔒

Privacy First

No user accounts. No email required. No tracking cookies. Files are accessed only via unguessable tokens and are deleted on schedule.

How It Works

1

Choose your file Drag and drop a file onto the upload area or click to browse. You can select multiple files at once. Total upload size up to 1 GB.
2

Get your share link After uploading, a unique share link and QR code are generated instantly. Copy the link or scan the QR code with any camera app.
3

Recipient downloads The person you shared with opens the link in any browser and downloads the file — with a real-time progress bar. No account, no friction.
4

Files self-destruct After 24 hours the transfer link expires and all files are permanently deleted from our servers. Nothing lingers.
