Go to quickbridge.app in any browser. The QR code and a 6-digit PIN appear immediately. Leave this tab open.
Step 2: Join from your phone
On your phone, scan the QR with the Camera app or open quickbridge.app and enter the PIN. The transfer page opens in your mobile browser.
Step 3: Match the verification codes
Both screens display a short emoji sequence. Confirm they are the same on both devices before sending.
Step 4: Find and send your PDF
Tap the file picker on your phone. On iPhone, the Files app opens, navigate to where the PDF is saved. On Android, look in Documents or Downloads. Select the PDF and tap Send.

Frequently Asked Questions
I received a PDF on WhatsApp. Can I send that to my laptop?
Yes. On Android, WhatsApp saves received files to internal storage and they appear in your file picker under Documents or the WhatsApp folder. On iPhone, long-press the file in WhatsApp, choose Share, then share it to Files. Once in Files, the QuickBridge file picker can reach it.
My PDF is in my email app. Can I transfer it without forwarding the email?
Yes. Save the attachment to your phone
Does this work from an office laptop on a corporate network?
QuickBridge does not use cloud file storage for your transfers. Files travel over encrypted WebRTC data channels, either directly between devices or through a TURN relay when required by network conditions. Signalling and relay services may process connection metadata needed to establish and maintain a connection.
Will the PDF be altered in transit?
QuickBridge transfers files as raw binary data without re-encoding or compressing them. When both devices support digest verification, the receiver computes an incremental SHA-256 hash to confirm the received file matches the sender
Can I send multiple PDFs in one session?
Yes. Select multiple files in the file picker, or send them one after another without re-scanning. The connection stays open until you close the tab.
Is there a file size limit for PDFs?
512 MB by default when receiving in memory on desktop browsers (300 MB on iOS Safari, 500 MB on Android). PDFs are rarely that large, so this is not a practical constraint. In desktop Chromium browsers that support direct disk saving, enabling
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.
