How to Decode QR Codes Online

QR codes are everywhere—product packaging, restaurant menus, event tickets, and business cards. Sometimes you have a QR code image saved on your computer but no phone camera to scan it. An online QR code decoder lets you upload the image and extract the data inside.

What Data Can QR Codes Contain?

• URLs: The most common use—links to websites, app stores, or landing pages.
• Plain text: Messages, notes, or instructions.
• WiFi credentials: SSID, password, and encryption type for quick network joining.
• Contact info (vCard): Name, phone, email in a scannable format.
• Email or SMS: Pre-filled recipient, subject, and body.

When to Use an Online Decoder

• You received a QR code as an image file (PNG, JPG) and want to see what it contains.
• You're testing QR codes you generated and want to verify the data.
• You need to extract a URL from a QR code in a document or screenshot.
• Your phone camera isn't available or doesn't have a QR scanner.
