Common Questions

Why did I get a colour warning?

Contrast is key. Scanners read the difference between light and dark.

However, this warning is just a guideline. Many modern phones can read "suboptimal" colour combinations perfectly fine.

Test and Adjust: Always scan the preview with your own phone. If it works, ignore the warning! If it struggles, try darkening the foreground dots slightly.

How do I create an updateable QR code / link?

QR codes are permanent, but you can make them "updateable" by using a redirect on your own domain.

YOUR DOMAIN

Point your QR code to something like yoursite.com/qr.

Later, you can change where that link (yourSite.com/redirect) goes in your domain settings. The QR code stays the same, but the destination changes.

Need a domain? We recommend Namecheap. You can get a domain for roughly $10/year and use their free URL forwarding. No hosting or website required.

Easy redirect creation guide

What size image should I use?

Any image will do!

However, for logos and photos, square images work best.

A resolution of around 1000x1000 pixels is optimal. This ensures your file/image looks crisp when printed.

My issue is not listed / Scanning issues

Is your QR code very complex?

If you have a lot of text or data, the QR pattern becomes very dense. The on-screen preview is scaled down, which might make it look blurry to a phone camera.

This can happen when previewing large QR codes with the Poster/Lost pet frame*.

Solution: Download the saved file or print it out. The full-resolution file is much clearer and easier for cameras to read than the small preview window.

How many QR can I generate at once?

In Batch Mode, you can generate hundreds of codes. We recommend keeping batches under 500 lines at a time to prevent your browser tab from freezing.
