Send Anywhere and Similar File-Sharing Apps/Websites: Features, Benefits, Pros & Cons (Knowledge Base)

📅 04 Jan 2026 📂 General 👁 64 views

File sharing tools like Send Anywhere solve a common IT problem: moving files quickly between devices and people—often across different platforms (Windows/macOS/Android/iOS)—without complex setup. However, not all tools work the same way. Some use peer-to-peer (P2P) real-time transfer, while others upload to a temporary cloud link, and some provide continuous synchronization.

This article explains how Send Anywhere works, compares it with similar apps/websites, and provides practical guidance for selecting and using the right option securely.

Technical Explanation: How These Tools Transfer Files

1) Real-time P2P transfer (device-to-device)

  • Files move directly between sender and receiver.

  • Usually faster on LAN and avoids storing files on a vendor server.

  • Requires both devices to be online at the same time.

Examples: Send Anywhere “6-digit key” mode, Snapdrop, ShareDrop, LocalSend, FilePizza. 

2) Cloud link transfer (upload → share link → download)

  • Sender uploads to the provider’s servers; receiver downloads later.

  • Better for async sharing (receiver can download later).

  • Depends on server availability, retention/expiry rules, and account limits.

Examples: WeTransfer, Wormhole (encrypted storage for limited time). 

3) Continuous sync (two-way folder synchronization)

  • Keeps folders in sync between devices continuously.

  • Best for ongoing workflows (backup, team folders).

  • Needs planning to avoid conflicts and accidental deletions.

Example: Syncthing. 

Send Anywhere (Primary Topic)

What it is

Send Anywhere is a cross-platform file transfer solution known for its “6-digit key” method—simple real-time sending without needing an account. 

Key Features

  • 6-digit Key Transfer (real-time):

    • Generates a one-time 6-digit security key.

    • Key is valid for a short window (commonly described as one-time use within ~10 minutes). 

  • Direct transfer behavior (in key mode):

    • Documented as direct device-to-device transfer and not stored on the server during key-based sending. 

  • Encryption during transmission:

    • Vendor support states files are encrypted during transmission. 

  • Share links / time-limited sharing options:

    • Send Anywhere also describes a “share for 24 hours” style option (implementation varies by platform/version). 

  • Cross-platform support:

    • Mobile apps + desktop + web usage (common deployment pattern for mixed environments). 

Benefits (Why IT teams like it)

  • Fast ad-hoc sharing (especially between phone ↔ PC).

  • No account required for basic usage (lower friction).

  • Useful for support workflows (collect logs, export data, share installers quickly).

Pros

  • Simple workflow (key/QR style sharing).

  • Works across many devices.

  • Key-based transfer is designed for short-lived access (reduced “long exposure” risk). 

Cons / Limitations

  • Real-time dependency: sender and receiver typically must be online simultaneously for key-based sending.

  • Network constraints: restrictive NAT/firewalls can impact direct transfer performance.

  • Operational control: in businesses, you may need policy controls (DLP, audit logs) that consumer tools don’t provide.

Similar Apps/Websites (Alternatives)

A) LocalSend (Best “AirDrop-like” for mixed OS on the same network)

What it is: Open-source, offline-first sharing over local network; emphasizes “nearby devices” sharing and encryption. 

Features & benefits

  • No internet required (LAN/Wi-Fi). 

  • End-to-end encrypted via HTTPS (as stated by F-Droid listing). 

  • Cross-platform (Windows/macOS/Linux/Android/iOS). 

Pros

  • Excellent for internal office/LAN transfers.

  • Open-source and often easier to justify for privacy-sensitive environments.

Cons

  • Not ideal for sharing to external users outside your LAN unless you set up routing/VPN.

B) Snapdrop / ShareDrop (Browser-based, quick P2P sharing)

Snapdrop: “nearby” sharing in a browser; P2P and open-source messaging. 
ShareDrop: WebRTC-based P2P sharing, no server upload “first.” 

Pros

  • Nothing to install (works in modern browsers).

  • Great for quick one-time transfers.

Cons

  • Same-network discovery is usually best; across networks can be inconsistent.

  • Browser limitations: large files may be less stable than native apps.

Note: Public Snapdrop project status has changed over time (community notes acquisition/branding changes). 

C) FilePizza (Best for “send a link, stream P2P”)

What it is: WebRTC direct browser-to-browser transfer; files don’t pass through the service server; sender must keep the tab open. 

Pros

  • No uploads to third-party storage.

  • Extremely simple “share a link” workflow.

Cons

  • Sender must remain online with the browser open until transfer completes. 

  • Can struggle on restrictive corporate networks.

D) Wormhole (Best for secure sharing with short-lived encrypted links)

What it is: File sharing with end-to-end encryption and auto-expiring links; files are deleted after a short retention period (commonly described as 24 hours). 

Pros

  • Good balance of convenience + privacy for external sharing.

  • Asynchronous download (recipient can download later).

Cons

  • Retention window is limited (by design).

  • You still depend on the provider’s service availability.

E) WeTransfer (Popular cloud-link transfer for large files)

What it is: Upload files, share a link/email; emphasizes encryption and optional password protection. 

Pros

  • Very easy for clients/vendors.

  • Useful for large media deliverables; configurable expiry in many plans/workflows. 

Cons

  • Cloud-based: files are stored temporarily on provider servers.

  • Password protection and retention features can vary by plan/workflow; confirm before relying on it. 

F) Syncthing (Best for ongoing sync/backup between devices)

What it is: Continuous file synchronization between two or more devices, designed to keep your data under your control. 

Pros

  • Great for internal backup workflows and multi-device sync.

  • Decentralized approach (no mandatory central cloud).

Cons

  • More setup than “one-time send.”

  • Requires careful folder/permission planning to avoid accidental propagation of deletions.

Use Cases (Practical Scenarios)

1) “Send a file right now” (helpdesk / urgent sharing)

  • Best: Send Anywhere (6-digit key), LocalSend, Snapdrop/ShareDrop.

  • Why: Minimal steps; fast initiation. 

2) “Share with a customer/vendor who will download later”

  • Best: Wormhole, WeTransfer.

  • Why: Link-based download with expiry. 

3) “Regular folder sync between office PC and server/NAS”

  • Best: Syncthing.

  • Why: Continuous synchronization model. 

Step-by-Step: How to Use These Tools

A) Send Anywhere (6-digit Key Transfer – common workflow)

  1. Open Send Anywhere on the sender device.

  2. Choose files/folders to send.

  3. Generate the 6-digit key and share it with the receiver.

  4. Receiver opens Send Anywhere → enters the key to start receiving.

  5. Complete transfer (note: key is short-lived and one-time use). 

B) LocalSend (LAN sharing)

  1. Install/open LocalSend on both devices.

  2. Ensure both are on the same Wi-Fi/LAN.

  3. Select files → choose the detected target device → send.

  4. Accept on receiver. 

C) Wormhole (encrypted link sharing)

  1. Open wormhole.app.

  2. Upload/select files.

  3. Copy the generated link and share it securely.

  4. Receiver downloads before link expiry (often 24 hours). 

D) WeTransfer (cloud link)

  1. Go to WeTransfer.

  2. Upload files.

  3. Set options (password protection/expiry where available).

  4. Send via email or share link. 

Commands / Examples (When apps aren’t ideal)

Secure copy over SSH (best for sysadmin/server workflows)

# Copy a local file to a server
scp "report.zip" user@server.example.com:/home/user/

# Copy a folder recursively
scp -r "Logs/" user@server.example.com:/home/user/Logs/

rsync (efficient for large folders / incremental updates)

rsync -avh --progress "/path/source/" user@server.example.com:"/path/destination/"

Common Issues & Fixes

Issue: Transfer is slow / fails mid-way

Likely causes

  • Wi-Fi instability, low signal, or congested 2.4GHz band

  • Firewall/NAT blocking P2P/WebRTC

  • Device sleeps during transfer

Fixes

  • Switch to 5GHz Wi-Fi / wired LAN where possible

  • Temporarily allow the app through firewall

  • Disable sleep during transfer / keep screen awake

Issue: Receiver can’t find sender (LocalSend / Snapdrop-type tools)

Fixes

  • Confirm both are on same subnet/VLAN

  • Disable “AP isolation” on Wi-Fi router (if enabled)

  • Try direct IP mode (if the tool supports it) or use link-based alternative

Issue: Link expired

Fixes

  • Recreate transfer with longer expiry option (if available)

  • Use a tool designed for longer retention (or a managed cloud drive)

Security Considerations (Important)

  • Treat file links/keys as sensitive credentials. Anyone with the link/key can potentially access the file until expiry.

  • Prefer end-to-end encryption for sensitive data (example: Wormhole). 

  • For cloud-link services, use password protection where available and share the password via a different channel. 

  • Scan inbound files (AV/EDR) before opening, especially from external sources.

  • Verify integrity for critical files: share a hash (SHA-256) separately for confirmation.

Example hash generation:

# Windows PowerShell
Get-FileHash .\installer.exe -Algorithm SHA256

# Linux/macOS
shasum -a 256 installer.exe

Best Practices (IT-friendly)

  • Choose tool by data sensitivity + urgency + network context:

    • LAN internal: LocalSend 

    • Fast ad-hoc cross-platform: Send Anywhere 

    • External secure async sharing: Wormhole 

    • Client deliverables (common industry flow): WeTransfer with password if needed 

  • For business environments, document:

    • Approved tools list

    • Max file size policies

    • Retention expectations

    • Handling rules for confidential data

Conclusion

Send Anywhere is a strong choice for quick, cross-platform transfers—especially via its short-lived 6-digit key workflow. 
If you want a “local AirDrop alternative,” LocalSend is often the most practical. 
For secure external sharing with expiring encrypted links, Wormhole fits well. 
And for ongoing synchronization/backup-style workflows, Syncthing is the right model.
