Why Worm

Built for Speed, Privacy & Simplicity

Everything routes over your local network — nothing ever touches a third-party server.

Ultra Fast Local Speeds

Transfer large 4K videos and gigabyte archives directly over your local network without internet bandwidth bottlenecks.

No Mobile App Required

Connect any iOS or Android phone instantly by scanning a QR code with any browser application.

100% Private & Offline

Your files never leave your local wireless network. No third-party servers, no trackers, complete privacy.

Unlimited File Size

No arbitrary caps or premium tiers. Send an entire project folder or a full video library in one go.

Zero Configuration

Open the app and it just works — automatic device discovery with no accounts, pairing codes, or setup screens.

Cross-Platform Native

Purpose-built native apps for macOS and Windows, tuned for each OS rather than a generic web wrapper.

Getting Started

Three Steps to Your First Transfer

No setup wizard, no account — you'll be sending files inside a minute.

Install & Open

Download WORM for your OS and launch it — it joins your local network automatically.

Discover the Device

Nearby computers and phones on the same network appear instantly, or scan the on-screen QR code.

Drag, Drop, Done

Drop your files onto the target device and watch them arrive at full local-network speed.

Benchmarked

Real Local-Network Throughput

Because files never leave your router, WORM saturates your local link instead of your internet upload cap — measured against common alternatives for a 1GB transfer.

Questions

Frequently Asked Questions

Do my files ever touch the internet or a server?+

No. WORM transfers files directly between devices over your local network using direct device discovery. Nothing is uploaded to a cloud server at any point.

Can I send files to my phone without installing an app?+

Yes. Scan the QR code shown in the desktop app with your phone's camera to open a lightweight browser page — no App Store or Play Store install needed.

Is there a file size or transfer limit?+

There's no artificial limit. Transfer speed and total size are only bound by your device's storage and your local network's throughput.

Which operating systems are supported?+

Native apps are available for macOS 11 and later, and Windows 10/11. Mobile devices connect through any modern browser.

Is Worm really free to use?+

Yes, WORM is free. If you'd like to support ongoing development, you can leave a tip through the "Buy Me a Mandhi" button.
