Free QR Code Reader — Scan & Decode QR Codes from Images Online

What Is a QR Code Reader?

A QR code reader is a tool that scans and decodes QR (Quick Response) codes to extract the data embedded within them. QR codes can store URLs, text, contact information, Wi-Fi credentials, payment details, and much more — all in a compact, scannable square pattern.

Our online QR code reader lets you upload an image containing a QR code and instantly decode its contents — no app installation required. Simply upload a screenshot, photo, or saved QR code image and get the decoded data in seconds.

Why Use an Online QR Code Reader?

• No App Needed: Decode QR codes directly in your browser without installing any software.
• Desktop Friendly: Phone cameras read QR codes easily, but if you have a QR code image on your computer, this tool is the fastest way to decode it.
• Security Check: Before scanning a QR code with your phone, upload the image here to see where it links — protecting yourself from malicious URLs.
• Batch Processing: Quickly decode multiple QR code images without switching between apps.

Types of Data Stored in QR Codes

URLs & Website Links

The most common use — QR codes that redirect to websites, landing pages, or app download links. Always verify the URL before visiting to avoid phishing sites.

Plain Text & Messages

QR codes can contain plain text messages, notes, or instructions. These are often used on product packaging, museum exhibits, and educational materials.

Contact Information (vCard)

Business cards and event badges frequently include QR codes with vCard data — name, phone, email, and address — for quick contact saving.

Wi-Fi Network Credentials

QR codes can encode Wi-Fi SSID, password, and encryption type, allowing one-scan network access in offices, cafes, and hotels.

Payment Information

Payment QR codes are used globally for mobile payments, cryptocurrency transactions, and point-of-sale systems.

How to Use This Tool

1. Click the upload area or drag and drop a QR code image.
2. The tool scans the image and locates the QR code pattern.
3. Decoded data is displayed instantly — URLs, text, contact info, or other content.
4. Copy the decoded data or click through if it's a URL.

Common Use Cases

• Verify QR codes before scanning — Check where a QR code leads before opening it on your phone
• Decode screenshots — Extract data from QR codes received in chat messages or emails
• Marketing analysis — Decode competitor QR codes to see their campaign URLs and tracking parameters
• Recover lost links — Extract URLs from QR codes when the original link was lost
• Accessibility — Decode QR codes for users who can't use a phone camera

Best Practices

• Always verify decoded URLs — Use a safe URL checker to verify links extracted from unknown QR codes.
• Ensure image quality — Clear, high-contrast images decode more reliably. Avoid blurry or heavily cropped QR code images.
• Check for the full QR code — All four corner markers must be visible for successful decoding.
• Use proper image formats — PNG and JPG images work best. Avoid heavily compressed or low-resolution files.

Frequently Asked Questions

Can this tool read QR codes from screenshots?

Yes! Upload any image containing a QR code — screenshots, photos, saved images, or downloads. The tool processes the image to locate and decode the QR pattern regardless of how the image was captured.

Is it safe to scan unknown QR codes?

QR codes themselves are harmless — they just store data. However, the content they link to could be malicious. That's why using an online QR reader to preview the decoded data before visiting any URLs is a smart security practice. Check suspicious URLs with our Safe URL Checker.

Why can't the tool read my QR code?

Common reasons include: the image is too blurry or low-resolution, the QR code is partially cropped (missing corner markers), the image has heavy compression artifacts, or the QR code is damaged. Try uploading a clearer, higher-resolution image.

What types of QR codes can this tool decode?

This tool supports all standard QR code formats including QR Code Model 1, Model 2, and Micro QR codes. It can decode URLs, plain text, vCards, Wi-Fi credentials, email addresses, phone numbers, SMS messages, and geographic coordinates.
