Creating your first QR Code
Generating a QR code with QR Studio is simple and instant. Follow these steps:
- Enter your content: Paste a URL, text, or contact info into the "Content Data" field.
- Customize the look: Use the controls to adjust the color, background, and corner styles. You can even add a gradient!
- Add a logo (Optional): Upload your company logo to make the QR code branded.
- Download: Click "Generate QR" to preview, then download as PNG (for web) or SVG (for print).
Using Batch Mode
Need 100 different QR codes? Don't create them one by one.
CSV Format Requirement
Your CSV file must have a column named data. Optionally, add a name column to control the filenames of the downloaded images.
1. Click the Batch Generator tab.
2. Upload your CSV file.
3. Click Create ZIP.
4. The browser will generate all images and download a ZIP file automatically.
Understanding Error Correction
QR codes have a built-in redundancy feature called Error Correction Level (ECC). This allows the code to be scanned even if part of it is damaged or covered (e.g., by a logo).
| Level | Recovery Capability | Best Use Case |
|---|---|---|
| L (Low) | ~7% | Clean digital use, no logo. |
| M (Medium) | ~15% | Standard use. |
| Q (Quartile) | ~25% | Industrial environments. |
| H (High) | ~30% | Codes with logos or artistic designs. |
Note: Higher error correction levels result in denser QR codes (more dots), which might be harder to scan at small sizes.
Best Practices for Printing
- ✓ Always use SVG: For billboards, posters, or packaging, use the SVG format to ensure lines remain crisp at any size.
- ✓ High Contrast: Ensure there is enough contrast between the foreground (QR code) and the background. Dark code on light background is best.
- ✓ Quiet Zone: Leave some white space (padding) around the QR code so the scanner can detect the edges.
- ✗ Don't Invert Colors: Many scanners cannot read a white QR code on a black background. Stick to dark-on-light.
