Step-by-Step Instructions
Step 1: Open QuickBridge on your computer
Go to quickbridge.app in any browser on your Windows or Mac. A QR code and 6-digit PIN appear on screen. This is the session your phone will join.
Step 2: Scan the QR code with your phone
Open the Camera app on your iPhone or Android and hold it over the QR code on your computer screen. The transfer page opens in your mobile browser. Alternatively, open quickbridge.app on your phone and enter the PIN.
Step 3: Confirm the emoji codes match
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: Select your video and tap Send
Tap the file picker on your phone. Choose the video from your camera roll or Files app. It starts streaming immediately over the direct connection. No upload step.
Step 5: Save the video on your computer
On Chrome, Edge, or Brave, auto-save streams the video directly to disk as it arrives. On other browsers, a download prompt appears. Either way, the video transfers as raw binary data without re-encoding or quality loss.
Frequently Asked Questions
Will the video arrive compressed?
No. QuickBridge sends the exact bytes your phone provides. There is no transcoding, resizing, or quality reduction at any point. A 1 GB video recorded in 4K arrives as a 1 GB 4K video.
Is there a video 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) with the File System Access API, enabling auto-save raises the ceiling to 10 GB by streaming directly to disk rather than buffering in RAM.
What video formats does it support?
Any format your phone produces: MP4, MOV, HEVC, AVI, MKV, or anything else. QuickBridge does not inspect or convert the file. Whatever the phone sends, the computer receives.
How fast is the transfer?
On the same Wi-Fi network, QuickBridge transfers directly between the two browsers at local network speed, typically 20 to 80 MB/s depending on your router. A 1 GB video takes 15 to 50 seconds. Over different networks, it uses an encrypted relay, which is slower but still faster than uploading to a cloud service.
Can I send multiple videos at once?
Yes. The file picker on iOS and Android supports multi-select. Select several videos and they queue and transfer in sequence over the same connection, without re-scanning the QR.
Why is this better than WhatsApp or Telegram?
WhatsApp compresses videos to reduce data usage and limits file size to 2 GB. Telegram has a 2 GB limit and routes files through its servers. QuickBridge sends the original file directly between your browsers with no cloud storage upload and no compression.
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.
