A free browser tool for transferring files and text between devices using direct WebRTC encryption, with optional internet relay after explicit permission.
The story so far
Textunnel is a free browser-based file and text sharing service designed for transfers between phones and computers. Users open the site on both devices, create a room on one device, and join it on the other using a shared code or QR code. The service prioritizes direct WebRTC connections for encryption and privacy, with optional internet relay available only after users explicitly grant permission in each tab.
The tool supports files up to 256 MiB through share links and folder packing, with larger room files requiring disk-saving APIs. Text transfers are limited to 64 KiB encoded messages. Transfers use WebRTC transport encryption, and users can set room passwords for additional security. The service requires no account creation, installation, or subscription and works across browsers on different devices and operating systems.

Questions and answers
How large a file can I send?
Share links and folder packing accept up to 256 MiB. After explicit relay permission, broker fallback accepts up to 25 MiB per file. Receiving room files over 256 MiB requires a supported disk-saving API; browser and device limits still apply.
Is every room end-to-end encrypted?
WebRTC data channels use transport encryption. Online signaling uses an internet broker. If you explicitly allow content relay, public-room broker payloads are not encrypted against the broker unless you set a room password.
Can it work without internet?
Open and cache the site before going offline. Nearby devices on a reachable local network can exchange offline connection QR codes. Guest Wi-Fi isolation, VPN routing and browser restrictions can prevent a direct connection even on the same Wi-Fi.
Is there any fee or subscription required when contacting support?
There is no fee to send feedback or a support request. The browser tool currently requires no paid subscription.
