QR code blurry
A blurry QR code usually fails because the camera cannot separate one module from the next. The fix is normally a better file, a better export, a larger size, or cleaner print production.
Why QR codes get blurry
- The QR image was exported too small and then scaled up later.
- A screenshot was used instead of the original source file.
- Heavy JPG compression softened the module edges.
- The print process introduced dot gain, smearing, or low-resolution output.
- The QR is displayed on a reflective or low-quality screen.
How to fix a blurry QR code
- Regenerate the code from the source instead of enlarging an old file.
- Use PNG at higher resolution or SVG/EPS for scalable print workflows.
- Increase the final physical size if the code contains a lot of data.
- Make sure the print vendor is not downsampling the file.
- Retest the regenerated QR on multiple phones before release.
A QR code should look sharp at the module edge level. If the edges look soft to your eyes, scan reliability is already at risk.
Best file formats to avoid blur
- SVG: best for scalable, crisp print and design handoff.
- EPS: useful in print and prepress workflows.
- High-resolution PNG: solid for digital and many print cases.
- JPG: acceptable for some uses, but usually the weakest choice for edge sharpness.
Prevent blur before launch
- Choose the correct export size at the start.
- Do not stretch a small QR image in Canva, slides, or page layout tools.
- Use 300 DPI or vector formats for print output.
- Test printed samples, not just the on-screen design file.
