Seamless File Transfer Between PC and Smartphone
Say Goodbye to Hunting for Cables
Want to move a proposal or design draft from your PC to your phone to review on the go? Or quickly pull field photos and videos from your phone into a document on your PC? For these everyday device-to-device transfers, do you still find yourself hunting for a USB cable, emailing files to yourself, or attaching them to your own chat?
These conventional methods come with more friction than you'd expect: mismatched cable connectors (Lightning, USB-C, etc.), email attachment limits, unwanted draft emails piling up, and compatibility issues across operating systems (Windows and iPhone, Mac and Android, and so on). With FS!QR, no special hardware or apps are needed — a browser and a camera (QR code) are enough to break down those barriers completely and achieve a truly seamless transfer.
How to Send Files from PC to Smartphone
Sending a file from your PC to a smartphone takes nothing more than a mouse drag and a scan.
- Upload files： Open the FS!QR homepage in your PC browser and drag and drop the file you want to send.
- Adjust settings (optional): If you like, adjust the retention period (e.g. 1 hour or 1 day) and optionally set ID/password protection.
- Show the QR code and scan it: Scan the QR code shown on screen after the upload completes with your phone's camera.
- Download on the phone: Run the download from the page that opens in the phone's browser and save the file.
This works even for someone else's phone that has no email configured or isn't linked to any chat account — as long as they're standing in front of you, the file is theirs instantly.
How to Send Files from Smartphone to PC
Sending photos taken on a smartphone or saved PDFs to a PC is just as straightforward with FS!QR's flexible interface.
- Upload from the phone: Open FS!QR in your phone's browser and upload the file by selecting it from your camera roll or Files app.
- Receive on PC (QR code): If your PC has a camera that can scan QR codes, scan the QR code shown on the smartphone's upload-complete screen to open the download page.
- Receive on PC (link entry): If the PC has no camera or scanning is difficult, type the share link shown on the smartphone's upload-complete screen into the PC browser. If you note down the share ID and 6-digit password, you can also open the file from the search page.
Why It's Safe to Use On the Go, on Shared PCs, or at Internet Cafés
File transfers on shared computers — a hotel PC on a business trip, a shared office machine, a co-working space terminal, or an internet café — always carry the risk of leaking account credentials or browsing history. Here's why FS!QR is especially well-suited to these environments.
- No login required: There's no need to log into a cloud storage service or email account, so no passwords or login sessions are left behind on the shared PC.
- Automatic data erasure: The service deletes its records and stored files when the retention period ends; backups and copies saved on recipient devices may remain.
- Encrypted Communication (SSL/TLS)： All transfers are encrypted, so third parties on the same network — such as a public Wi-Fi hotspot — cannot eavesdrop on your data.
Pro Tip: Use FS!QR as a Cross-Device Clipboard
FS!QR is just as useful for quickly copying text or URLs between devices as it is for large files.
For example, if you need to move a long or complex URL you found on your PC, a two-factor authentication code received on your phone, or a Wi-Fi encryption key, you can use FS!QR's Note (collaborative note) feature or create a temporary text file (.txt) and upload it as a shared clipboard between devices. Move information cleanly, without typos from manual entry or unnecessary communication history.
