Step-by-Step Instructions
Step 1: Open QuickBridge on the receiving device
Go to quickbridge.app in any browser on the device that will receive. A QR code and 6-digit PIN appear. No account, no installation needed.
Step 2: Open QuickBridge on the sending device
On the other device, scan the QR code with your camera, or open quickbridge.app and enter the PIN. Both devices can be on the same Wi-Fi or completely different networks.
Step 3: Verify the emoji security codes
Both devices display an emoji sequence derived from the DTLS certificate fingerprints used in their WebRTC connection. Comparing the sequences through a trusted channel helps users detect a possible man-in-the-middle attack. The comparison does not indicate whether the connection is direct or uses a relay.
Step 4: Send the file
On the sending device, drag a file into the browser tab, use the file picker, or paste from your clipboard. The transfer starts the moment you drop it.
Step 5: Receive on the other device
The file arrives as a standard browser download. On Chromium-based browsers with auto-save enabled, it streams directly to disk without a prompt.
Frequently Asked Questions
Do both devices need to be on the same Wi-Fi?
No. QuickBridge attempts a direct browser-to-browser connection first. If both devices are on the same network, the file travels locally at full network speed. If they are on different networks, QuickBridge routes through an encrypted relay. Either way, no USB cable is needed.
What operating systems does this work with?
Any combination: Windows, macOS, iOS, Android, Linux, ChromeOS. The only requirement is a modern browser on each device. Chrome, Firefox, Safari, Edge, and Brave are all supported.
How is this different from Bluetooth file transfer?
Bluetooth transfers are slow (roughly 2 to 3 MB/s) and require pairing, which involves confirmation codes on both devices. QuickBridge pairs via QR scan and transfers at Wi-Fi speed. A 100 MB file takes a few seconds over Wi-Fi versus several minutes over Bluetooth.
Is there a file size limit?
512 MB per file by default when receiving in memory (with lower limits on mobile, such as 300 MB on iOS Safari, and a 1 GiB aggregate ceiling). On Chromium-based browsers (Chrome, Edge, Brave), enabling auto-save allows files up to a configured 10 GB ceiling by streaming them directly to disk.
Do I need to install anything?
No. QuickBridge runs entirely in the browser. No app, no extension, no driver. Open the site on both devices and you are ready to transfer.
What happens if the connection drops mid-transfer?
QuickBridge detects the disconnection and attempts to reconnect automatically. If the reconnection succeeds, you can restart the file transfer. Outgoing transfers are flagged as retryable so you do not have to re-select the file.
Is QuickBridge free?
QuickBridge is free to use, with no subscription required. Advertisements may appear on the site to help support its ongoing operation.
What is QuickBridge?
QuickBridge is a browser-based peer-to-peer file transfer tool. Open the site on both devices, scan the QR code or enter the 6-digit PIN, and files stream directly between the two browsers over an encrypted WebRTC channel. No account, no app install, and no cloud file storage.
Who is QuickBridge best for?
QuickBridge is best for anyone who needs to move files between two devices in real time without a USB cable, account, or app install. Both devices need to have a browser open at the same time. Choose a cloud service like Google Drive or WeTransfer when the recipient will not be online right away, or when you need the same file to reach several people at different times.
