About QR Scan to PDF
QR Scan to PDF turns your phone into a wireless document scanner for your computer: scan a QR code on-screen to open a peer-to-peer WebRTC connection, then use your phone's camera to capture pages one by one — each photo streams straight to your browser and compiles into a single PDF. There's no app to install. The connection is direct when possible and may use encrypted WebRTC relay infrastructure when direct connectivity is unavailable; the application does not intentionally store transferred files after the session. It's the fastest way to digitize paper documents when you don't have a physical scanner nearby, using hardware you already have in your pocket.

Search intent
Before vs after
Before
You have a document that needs a quick change, but the workflow is blocked by file size, formatting, security, or organization issues.
After
The PDF becomes ready for sharing, submission, printing, or archival with the exact changes you needed without leaving the browser.
Common mistakes
- !Skipping a quick preview before downloading the final file.
- !Not checking the output on a real device before sending it to a colleague or portal.
- !Using the wrong tool for the job because local PDF editing and conversion are not interchangeable.

Frequently asked questions
Do I need to install an app on my phone?
No. Your phone just needs a modern browser (Safari or Chrome). Open the URL from the QR code and start scanning.
How is the data transferred?
Via PeerJS (WebRTC) — a direct peer-to-peer connection between your phone and computer. Data never passes through any server.
Does it work on the same WiFi network?
WebRTC works across any network — same WiFi, different networks, or even mobile data. Signaling uses PeerJS's free servers only for initial handshake.
How many pages can I scan?
No limit. Keep taking photos and they pile up on the desktop PDF builder. Compile into one PDF when done.
Is the connection secure?
Yes. WebRTC connections are encrypted with DTLS. No data is stored on any server at any point.
