MaiImg QR Code Generation Guide
Need a QR code for an image? Upload → get QR → share. The entire process takes 30 seconds and requires no account for basic use.

Quick Start: 4 Steps
Step 1 — Open maiimg.com
Step 2 — Upload your image (drag-and-drop or click to browse)
- Supported: PNG, JPG, JPEG, GIF, WebP
- Max size: 50 MB per image
- Batch: up to 25 images at once
Step 3 — Wait 3–5 seconds for processing
Step 4 — Download the QR code (right-click → save, or copy to clipboard)
Done. The QR code links directly to your image.
What the QR Code Does
When someone scans the QR code with their phone camera:
- Their browser opens automatically
- The full-resolution image loads
- They can view, zoom, and (if allowed) download the image
No app installation required. Works on every smartphone with a camera.
Customizing Your QR Code’s Behavior
After upload, adjust settings to control the experience:
Allow or Block Downloads
Toggle the download button. When off, viewers can see the image but can’t save it to their device.
Set a View Limit
Cap how many times the QR code can be scanned. After the limit, scans show an “unavailable” message.
Set an Expiration
The QR code stops working after your chosen date. Perfect for time-limited campaigns or events.
