FAQ
Frequently asked questions
Everything you need to know before your first transfer.
Is FileTransferX free to use?
Yes. Sending and receiving files does not require an account, a subscription, or payment of any kind.
Do I need to create an account?
No. FileTransferX has no sign-up and no login. Open the site, choose Send or Receive, and you are ready to go.
Where are my files stored?
Nowhere. FileTransferX moves files from one device to another; it does not keep a copy on a server. Once a transfer finishes or the tab is closed, there is nothing left behind to store or retrieve.
How do two devices connect to each other?
The sending device generates a QR code and a short transfer code, such as X7K9-P2. Scanning the code or typing it into the receiving device pairs the two for a single transfer session.
How long does a transfer code stay valid?
Transfer codes are short-lived and tied to one session. If a code expires before it is used, just start a new send session for a fresh one.
Is there a file size limit?
FileTransferX reads and sends files in small chunks instead of loading them into memory all at once, so it is built to handle large files. Practical limits still depend on your device’s available memory and your network connection.
Can I send multiple files at once?
Yes. Select or drag in as many files as you want to send in a single session, and the receiving device can review and accept them together.
Does it work between a phone and a computer?
Yes. FileTransferX works between any combination of phones, tablets, and computers, as long as both are using a modern browser.
What happens if I close the browser tab mid-transfer?
The transfer stops. Since nothing is stored on a server, an interrupted transfer cannot be resumed from where it left off — you would need to start a new session.
Does FileTransferX work on any network?
It works on most networks, including home Wi-Fi and mobile data. Some restrictive networks, like strict corporate firewalls, can block a direct connection between devices; when that happens, FileTransferX automatically uses a fallback path so the transfer can still complete.
Which browsers are supported?
Any recent version of Chrome, Edge, Firefox, or Safari on desktop or mobile. No extension or app install is required.
