How to Scan a QR Code from an Image: Complete Guide

QR codes are everywhere — on product packaging, restaurant menus, business cards, event tickets, and marketing materials. But what if you have a screenshot or photo of a QR code and need to read what's inside? This QR Code Scanner tool lets you upload any image containing a QR code and instantly decode its content — no phone camera needed.

What Is a QR Code Scanner?

A QR code scanner reads the encoded data inside a QR (Quick Response) code image. Unlike camera-based scanning apps, this tool works with any image file you already have — screenshots, downloaded images, photos, or exported QR codes.

QR codes can store different types of information:

Content Type	What It Contains	Example
URL	Website links	https://example.com
WiFi	Network name, password, encryption	Auto-connect credentials
vCard	Contact information	Name, phone, email, organization
Email	Pre-filled email	Address, subject, body
Phone	Phone number	Tap-to-call number
Plain Text	Any text content	Notes, codes, messages

This scanner automatically detects the content type and parses the structured data so you can read it clearly.

How to Scan a QR Code from an Image

Step 1: Upload Your Image

Click the upload area or drag and drop an image file containing a QR code. Supported formats:

• PNG — best for screenshots and digital QR codes
• JPEG — works well for photos of printed QR codes
• WebP — modern web image format
• GIF — static GIF images with QR codes

The maximum file size is 1 MB, which covers virtually all QR code images.

Step 2: Click "Scan"

After uploading, click the Scan button. The tool processes your image server-side:

1. Normalizes the image format and size
2. Extracts pixel data for QR pattern recognition
3. Detects and decodes the QR code
4. Identifies the content type automatically
5. Parses structured data (WiFi credentials, contact info, etc.)

Step 3: Read Your Results

The results appear in two sections:

• Scan Results — the raw decoded content, detected content type, and character count
• Parsed Details — structured breakdown specific to the content type (e.g., WiFi network name and password shown separately)

Understanding the Results

Decoded Content

The full text encoded inside the QR code, exactly as stored. This is the raw data before any parsing.

Content Type

The scanner automatically identifies what kind of data the QR code contains:

• URL — a web address starting with http:// or https://
• WiFi Network — network configuration in the standard WIFI: format
• Contact Card (vCard) — contact information in vCard format
• Email — a mailto: link with optional subject and body
• Phone Number — a tel: link for direct calling
• Plain Text — any other text content

Parsed Details

Depending on the content type, you'll see specific fields extracted from the QR code:

For URLs:

• Domain name and full URL displayed separately for easy reading

For WiFi Networks:

• Network Name (SSID)
• Password
• Encryption type (WPA, WEP, or Open)
• Whether the network is hidden

For Contact Cards (vCard):

• Name, phone number, email
• Organization and job title
• Address and website

For Email Links:

• Email address, subject line, and body text

For Phone Numbers:

• The phone number ready to call

Tips for Better QR Code Scanning

1. Use clear, high-resolution images. Blurry or low-resolution photos may fail to decode. Screenshots of QR codes work best.

2. Ensure the entire QR code is visible. The scanner needs all four corner markers (the large squares) to detect the code. Cropped or partially obscured QR codes cannot be read.

3. Avoid extreme angles. If you're photographing a printed QR code, try to capture it as straight-on as possible. Minor angles are fine, but severe perspective distortion can prevent decoding.

4. Check image contrast. QR codes need clear contrast between dark and light modules. Very faded, washed-out, or low-contrast images may not scan successfully.

5. The tool handles inverted QR codes. Light-on-dark (inverted) QR codes are automatically detected and decoded.

6. Try different image formats. If a JPEG doesn't scan, try converting to PNG. JPEG compression artifacts can sometimes interfere with QR pattern detection.

Common Questions

Can I scan a QR code from a screenshot?

Yes. Screenshots are actually the best source for QR code scanning because they preserve the exact pixel data without camera blur, compression artifacts, or perspective distortion. Simply take a screenshot of the QR code, upload it, and scan.

What if the scanner says "No QR code found"?

This usually means one of:

• The image is too blurry or low-resolution
• The QR code is partially cropped or obscured
• The image has very low contrast
• The file isn't actually a QR code (it might be a different type of barcode)

Try using a clearer image or a higher-resolution version.

Is my uploaded image stored on the server?

No. The image is processed in memory during the scan and is not stored, saved, or logged on the server. Your data remains private.

What's the difference between a QR code and a barcode?

A barcode (like UPC codes on products) stores data in one dimension using vertical lines. A QR code stores data in two dimensions using a grid of dark and light squares, allowing it to hold much more information — typically up to 4,296 characters.

This tool specifically reads QR codes, not traditional 1D barcodes.

Can I scan multiple QR codes from one image?

The scanner reads the first QR code detected in the image. If your image contains multiple QR codes, crop the image to isolate the one you want to scan, then upload it.

What QR code versions are supported?

The scanner supports all standard QR code versions (1 through 40) and all four error correction levels (L, M, Q, H). This covers virtually every QR code you'll encounter.

How is this different from using my phone camera?

Your phone camera scans QR codes in real-time from the physical world. This tool scans QR codes from image files you already have — screenshots, downloaded images, emailed QR codes, or photos saved on your device. It's useful when:

• You received a QR code as an image file
• You want to verify what a QR code contains before scanning it with your phone
• You're on a desktop computer without a camera
• You need to extract and copy the decoded text

When to Use a QR Code Image Scanner

• Verify QR codes before visiting links — check where a URL goes before opening it in your browser
• Extract WiFi passwords — decode a WiFi QR code to see the password in plain text
• Read contact cards — extract name, phone, and email from a vCard QR code
• Archive QR code data — decode and save the content from event tickets or receipts
• Accessibility — decode QR codes when you can't use a camera-based scanner
• Desktop workflow — scan QR codes received via email, chat, or file sharing without picking up your phone

Note: This tool processes QR codes conforming to the ISO/IEC 18004 standard. For best results, use clear images where the QR code occupies a significant portion of the image area.
