A few clear answers.

Open your phone’s camera or the Valid QR Scan scanner, then point it at the whole QR code. Keep it steady and review the decoded text or link before opening it. In the browser scanner, allow camera access when prompted.

Open the Camera app and point it at the code. If nothing appears, check your camera’s QR settings or try Google Lens or the QR scanner in Quick Settings, where available. Features vary by phone; you can also use Valid QR Scan in your browser.

Open Camera in Photo mode and hold the QR code inside the frame. Tap the link that appears after checking the destination. You can also use Code Scanner in Control Center.

Safety depends on the service and what you encode. Valid QR Scan generates codes in your browser without uploading the QR content for processing. A QR code is not encryption, anyone with the image can read its contents, including a WiFi password.

Point a compatible phone camera or WiFi scanner at the code, check the network name, and confirm the connection. A browser scanner can read the network details but cannot directly join the network. Only connect to networks you trust.

Open Camera, point it at the WiFi QR code, and tap the network prompt to join. Make sure WiFi is enabled and you are within range. If no prompt appears, check that the code contains WiFi settings and that the password is current.

Open the Valid QR Scan scanner and choose the saved image on your device. Keep the complete code and its blank border visible. The image is decoded locally in your browser, so you can read a code shown on the same phone.

Yes. Many phones can scan QR codes with their built in camera. You can also open Valid QR Scan in a browser and use the camera or select an image without installing an extra app.

Open Valid QR Scan in your browser and select an image containing the code, or start the camera and allow webcam access. For a code on your laptop screen, save a screenshot and select that file.

Clean the lens, improve the lighting, and keep the entire code and its blank border in view. Avoid glare and blurry images. If the browser camera will not start, check camera permissions or select a saved image instead.

Open the Valid QR Scan generator, choose a content type, and enter your link, text, or WiFi details. Download the code and test it before sharing. No account is required; anyone who scans the code can read the information you put in it.

Static QR codes have no built in expiry date, but their linked websites or files can become unavailable. WiFi codes stop connecting if the network details change. Dynamic codes from other services may depend on an active subscription or redirect service.

Scanning, generation and image processing run in your browser. Images and decoded contents are not sent to our servers. Loading the website itself still makes normal network requests.

Yes, after a connected first visit has cached the app. Open Install app to check the offline status. Camera support still depends on your browser and device; opening a web link needs a connection.

No. A code can decode correctly and still lead to a deceptive or harmful website. Review the actual hostname, and never enter credentials just because a QR code asks you to.

Allow camera permission, use an HTTPS connection, and close apps that might be using the camera. If camera access is unavailable, choose an image instead.

This release reads one QR code per image. Crop your image around the code you need, including its white border.

Create PNG, SVG, WebP and PDF files. SVG preserves vector modules; PDF places a high resolution QR image at your chosen physical size. Some browsers fall back from WebP to PNG.

No. Automatic history is off until you enable it. WiFi and recognized Bitcoin or payment payloads are excluded from automatic saving. Use Save locally only when you want to retain a sensitive result.
