How It Works

1. Upload — sign in, then drop or select files on the sending device. Choose expiry, an optional password and a download limit.
2. Share — copy the link, send it by email, use your phone's share menu, or show the QR code.
3. Download — open the link on the other device and tap Download. No account needed to receive.

Large files and weak connections

Files are uploaded in 6 MB chunks. If your connection drops, SM Share retries automatically and continues from the last finished chunk. If you close the page, select the same file again and the upload resumes where it stopped. Each file can be up to 5 GB.

iPhone tips

In Safari, tap Select Files and choose Photo Library or Browse. Keep the page open while uploading — iOS pauses background browser tabs.

Security

Links use long random codes. Files are private in storage and are only reachable through short-lived download links created after the share link is checked.
