Large file transfer software for UDP transfer and cloud sharing.
Send files between devices, share browser download links, sync folders, or collect uploads. Choose UDP endpoint transfer, WarpShare cloud sharing, or both according to your workflow.

WarpDirect
Send files between your computers and NAS.
A large master file and a folder of small assets place different demands on a transfer tool.
WarpDirect supports both types of transfer.
Transfer a 500 GB master or a folder of 50,000 small assets between supported endpoints. Speed depends on your UDP plan, network, and device performance.
See the complete product page: WarpDirect
Built for large files & high file counts
Automatic resume on disconnect
Resume an interrupted transfer from its saved progress.
Automatic connection setup
WarpSend attempts a direct connection without inbound port forwarding. Paid UDP tiers include Shuttle fallback when a direct route is unavailable.
Encrypted transfer paths
Current encryption-capable endpoints protect file data in transit across direct and relay routes.
Transfer history and notifications
Check transfer status and receive completion or failure notifications.
Multi-platform
macOS, Windows, Linux, Synology NAS.
Drag and drop
Drop files or folders into WarpDirect. No setup per transfer.
WarpShare
Share files through a browser link.
Clients need a way to download a delivery when they are ready, even after your computer goes offline.
WarpShare keeps uploaded files available by link.
After uploading, send a link that recipients can open in their browser with no account required. Files remain available while your device is offline. WarpShare bills upload volume, with no extra download fees and no UDP subscription required.
See the complete product page: WarpShare
KEY CAPABILITY
Your device can go offline
Once the upload finishes, recipients can download until the link expires, even while your device is offline.
- ∞
- recipients per link
- $0
- extra fees for repeat downloads
- 0
- accounts required
Built for simple, reliable sharing at scale
No account needed for recipients
Anyone with the link downloads in a browser. No app, no signup.
Unlimited downloads per link
No per-download fees. Share with one person or a hundred.
No plan download speed cap
Recipients download without a plan speed cap. WarpShare works independently of UDP transfer plans.
Password protection
Add a password to any link. Only those with it can download.
Custom expiry
Choose when access to a sensitive delivery ends through its sharing settings.
Delivery tracking
See when a link was opened and how many times it was downloaded.
WarpFabric Global Delivery Network
Recipients download through WarpSend’s managed delivery layer, wherever they are.
WarpSync
Keep folders in sync between devices.
When folders change throughout a project, sending each update manually adds repeated work and makes changes easier to miss.
WarpSync transfers changes automatically.
Choose the folders and sync direction. WarpSync moves changes automatically, resumes interrupted transfers, and records activity for review.
See the complete product page: WarpSync
KEY CAPABILITY
One-way and two-way sync
Send changes from a source folder to a destination, or synchronize changes in both directions.
- Automatic
- change detection; timing varies
- 0
- scripts required
- History
- sync activity recorded
Built for continuous, automated sync
Hot folder automation
Drop a file in, it transfers automatically. No manual triggers.
Automatic resume on disconnect
Network drops don’t restart jobs. Picks up where it left off.
Any two endpoints
Connect supported computers, servers, and NAS devices in the locations where your team works.
Optimized for many files
Batches transfer work to reduce overhead when folders contain many small files.
Full visibility
Monitor every job from one dashboard. See what moved and when.
API access
Automate jobs and trigger syncs via REST API. No UI required.
Encrypted sync paths
Tunnel protects direct sync traffic; Shuttle encrypts chunks and its manifest before managed WarpFabric staging.
File Requests
Collect uploads by link, with optional delivery to your computer or NAS.
Collecting large files by email or through shared drives can mean attachment limits and extra access permissions.
File Requests provides a dedicated browser upload link.
Create a reusable link for a cloud inbox, or enable automatic delivery to a folder on your computer or NAS. Uploaders send in their browser with no account or app. Choose end-to-end encryption with WarpSignet when creating the request.
See the complete product page: File Requests
KEY CAPABILITY
A reusable link for incoming work
Give clients, photographers, vendors, or collaborators one upload link. Download submissions from the inbox, or have them delivered automatically to your receiving folder.
- 0
- uploader accounts required
- Offline
- endpoint can reconnect later
- Optional
- end-to-end encryption with WarpSignet
Built for secure, repeatable inbound delivery
No uploader account
Anyone with the link can send files or folders in a browser. No WarpSend login or install.
Endpoint can be offline
With automatic delivery enabled, WarpSend queues submissions until the receiving endpoint reconnects. Cloud collection needs no endpoint.
Optional end-to-end encryption
Set up WarpSignet and select encryption when creating the request to encrypt file contents in the uploader browser before cloud storage.
Password and expiry controls
Protect the link, set a collection deadline, or pause new submissions without breaking active uploads.
Submission limits
Control the maximum size per submission and optionally cap the number of submissions.
Ask who is sending
Collect a name, name and email, or allow anonymous delivery. Add an optional message.
Track every delivery
Review submissions and, when automatic delivery is enabled, see which files are waiting for the endpoint and which have arrived.
Transfer methods
Choose how the files reach their destination.
A direct connection moves files between online devices. Cloud sharing and collection let people send or receive in a browser. Choose the route that fits the recipient and the handoff.

Parallel packingResumeByte verify
Destination endpointStudio B · NASDirect device transfers
WarpDirect uses QUIC over UDP. Browser uploads and cloud delivery use separate routes.
Interrupted transfers
Recovery depends on the transfer method. Endpoint transfers can resume from saved progress; check the job status before relying on a delivered copy.
Device support
Install the Agent on macOS, Windows, Linux, or a supported Synology NAS for endpoint transfers and folder delivery.
Workspace activity
Manage transfer, sync, sharing, and collection activity from your WarpSend workspace.

Why the transport decides the transfer.
The engineering behind the four workflows: what changes over a WAN, why small files crawl, and what a realistic finish time looks like.
