FlashScan Pro is a free online tool to create and read QR codes and barcodes right in your browser. Unlike most online services, no data is sent to any server: all generation and decoding happens locally, on your device. You can even use it offline, for sensitive content — a Wi-Fi password, a business card, an internal link — without it ever leaving your machine.
Most online QR code generators send your content to their servers to produce the image — and some attach tracked links or ad redirects. FlashScan Pro works differently: the generation library runs entirely inside the page, your data stays with you, and the generated code contains exactly what you typed, with no intermediate server. Your scan history is stored locally and organized in folders; you can export or erase it anytime.
Our blog explains formats and best practices: the different types of QR code, choosing an error correction level, recommended print sizes and how to protect yourself from quishing, phishing via QR code.
