What is a file QR code and how does it work?

A file QR code is a type of QR code that links directly to a digital file, such as a PDF, ZIP, image, or document.

When someone scans the code using their phone or camera app, the file either:

• Opens directly in their browser, or
• Begins downloading automatically, depending on the file type and phone settings.

How it works:

• You upload a file to a QR code platform (like Linko).
• The platform hosts the file and gives you a QR code that points to it.
• Anyone who scans the QR code can access or download that file instantly.

Think of it as the fastest way to hand someone a digital file, no emails, no logins, no links needed.

Tips to make your file QR codes mobile-friendly

Most QR code scans happen on mobile devices, so your file delivery experience must be smooth.

✅ Use common file formats

• Stick to formats like PDF, JPG, or TXT. They open natively on most phones without extra apps.

✅ Keep file sizes under 5MB

✅ Test your QR on different devices

Before printing or sharing, scan your QR code on:

• Android
• Older phones

Ensure the file opens quickly and clearly.

✅ Add a call-to-action

Use phrases like:

• “Scan this for discount PDF”

This tells users what they’re getting before scanning.
