QR Code Scanner

Free QR code scanner (camera + upload, no sign-up)

This is a genuinely free QR code scanner that works in-browser with two modes: live camera scanning and image upload. No registration, no ads, and no tracking. Use it to scan WiFi QR codes, Google Review links, menu codes, payment codes, and product packaging. Because everything runs client-side, it stays fast and private—even on slow connections.

Why choose this scanner?

• Zero friction: Open the page, allow camera, and scan. No app install, no account.
• Camera + upload: Works as a free QR code scanner online with camera and as a QR code scanner from image when the camera is blocked.
• Privacy-first: Frames stay on-device. Great for sensitive QR codes like WiFi passwords or internal documents.
• Desktop-friendly: Use the upload option to decode screenshots when you are on a laptop or a locked-down corporate device.
• Fast decode: Uses @zxing/browser for quick detection and error correction, even on low-light captures.

Scan WiFi QR codes without typing

If you printed a WiFi QR from our generator, this free QR code scanner reads it instantly. No need to type SSIDs or passwords. Perfect for cafes, coworking spaces, and guest networks.

Scan Google Review QR codes

Local businesses share review links via QR. Use the camera to scan table tents, flyers, or receipts. If someone sends a screenshot, upload the image and decode it in seconds.

Menu and payment codes in low light

Restaurants and events often have dim lighting. The scanner handles common error correction well; just steady your hand and center the code. For the toughest cases, snap a photo and use the upload mode.

Bulk screenshots from desktop

When you get dozens of QR screenshots in Slack or email, you can drag-drop images one by one. This works as a QR code scanner for PC and a QR code scanner from gallery without any install.

Performance and technical notes

The page is lightweight for fast load. It avoids heavy analytics, keeping your scans private and responsive. The camera loop runs until you stop it; if permission is denied, the UI falls back to upload. For best accuracy, use high-contrast codes and avoid glare. If you need high-resolution print codes, generate them on the QR generator page first, then scan here to validate.

How to get the most reliable scans

1. Allow camera access and clean the lens for sharper focus.
2. Hold the code 6–12 inches away; avoid extreme angles.
3. Use good lighting or backlight from your screen when scanning printed codes.
4. For screenshots, crop tight around the QR before uploading.
5. If the code is tiny, zoom with your device camera, or request a higher-resolution version.

Comparing to mobile apps

Mobile QR apps often add ads, tracking, or upsells. This free QR code scanner runs in the browser, so you keep privacy and skip installs. It is ideal for temporary devices, kiosks, and shared laptops. If you already have a native scanner, keep this as a backup for uploads and desktop use.

Security and privacy

Scanning stays local: no frames or images leave your device. If the decoded result is a URL, decide before you click—especially for payment or login links. For internal teams, remind users to verify domains before opening.
