Step-by-Step Instructions
Step 1: Open QuickBridge on your PC and enable auto-save
Go to quickbridge.app in Chrome or Edge on your PC. Once the QR appears, find the auto-save toggle in the receiver panel and turn it on. This streams large files directly to disk instead of buffering in RAM, unlocking transfers up to the configured 10 GB ceiling.
Step 2: Choose a save location
When you enable auto-save, your browser prompts you to pick a folder. Select your Downloads folder or wherever you want the files to land. This is a one-time setup per session.
Step 3: Scan the QR on your phone
Use your camera to scan the QR code on your PC screen. The transfer page opens in your mobile browser. On iPhone that is Safari. On Android that is Chrome.
Step 4: Select your large file on the phone
Tap the file picker on your phone. Navigate to your video, archive, or large document. Select it and tap Send. A progress bar appears on both screens the moment it starts.
Step 5: Watch the progress and wait for completion
Both sides show a progress bar with estimated time remaining. For a 1 GB video on a home Wi-Fi network this typically finishes in 1 to 3 minutes. The file writes directly to your chosen folder on the PC as it streams.
Frequently Asked Questions
Why is direct transfer faster than uploading to a cloud service?
Cloud services upload the file to their servers over your internet connection, then you download it again on the other side. That is two full passes over your internet bandwidth. QuickBridge uses your local Wi-Fi network for both devices, which is typically 10-100x faster than your internet upload speed. A 1 GB file that would take 10 minutes to upload to Google Drive and download again can finish in under 2 minutes on a 5 GHz home network.
What is the actual file size limit?
512 MB per file with standard in-memory reception (with lower device-specific limits on mobile, such as 300 MB on iOS Safari, and a 1 GiB aggregate ceiling). Up to 10 GB when auto-save is enabled on the receiving PC. Auto-save uses the File System Access API (available in Chrome and Edge) to write directly to disk, bypassing the browser
Does auto-save work in Safari on Mac?
Safari does not support the File System Access API as of 2026, so auto-save (and the 10 GB limit) requires Chrome or Edge on the receiving side. Safari on the Mac can receive files in memory up to 512 MB. If you need to receive files over 512 MB on a Mac, use Chrome or Edge for Mac with auto-save enabled.
What happens if the connection drops mid-transfer?
QuickBridge has a transfer resume feature. If the connection drops, the receiving side holds the partial file in a 2-minute grace window. If the sender reconnects within that window, the transfer picks up from where it left off rather than starting over. The sender side shows a Resume button for interrupted transfers.
Can I send large video files from an iPhone?
Yes. The iOS Files app and the Photos picker both appear in the file picker. Videos from your camera roll and files in iCloud Drive are accessible. Note that very large ProRes videos (iPhone 15 Pro and later) can be several gigabytes per minute of footage. Make sure auto-save is enabled on the PC before sending.
Does transfer speed depend on my internet connection?
Only if both devices are on the same local network. In that case, QuickBridge creates a direct peer-to-peer connection using your router. Your internet speed is not involved and does not limit transfer speed. If the devices are on different networks (phone on cellular, PC on Wi-Fi), traffic routes through a TURN relay and is limited by the slower internet connection.
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.
