Make a Circle QR Code That Still Scans

A round QR code is a standard QR code restyled with rounded or dotted modules and framed inside a circle. The underlying data grid follows the normal QR standard, so it scans like any square code - the circular shape is purely a design choice.

Yes, when designed properly. The three finder patterns and the data grid still follow the QR standard, and the circular frame is decorative around them. As long as contrast is high, the quiet zone is preserved, and the code isn't distorted, circular codes scan reliably on any modern phone.

Yes. Center the logo on a solid background at a size that stays under about 30% of the code area, so it never overlaps a finder pattern. Set error correction to the highest level (H) first - it gives the code enough redundancy to stay readable behind a logo.

SVG is best for print because it's a vector and scales to any size without losing sharpness. For screens, a high-resolution PNG works well. For professional printing, supply SVG or a PNG at 300 DPI.

Not if they're built correctly. The scannable structure is identical to a square code. Problems only appear when contrast is too low, the quiet zone is removed, the code is stretched, or a logo covers a finder pattern - all of which are avoidable design choices.

Use level H, the highest of the four levels (L, M, Q, H). It recovers roughly 30% of a damaged or obstructed code, which gives you the redundancy needed to add a logo and apply rounded styling without breaking the scan.

Anywhere the surface is already round: stickers and labels, coasters, buttons and pins, wax seals, bottle caps, packaging lids, badges, and social profile rings. The shape reads as intentional on these formats instead of looking pasted on.

Yes. Brand colors work well as long as the contrast between the modules and the background stays high - dark modules on a light background is the safest pairing. Test the combination before printing, since low-contrast palettes are the most common cause of failed scans.

As a rule of thumb, keep it at least 2 × 2 cm (about 0.8 inches) for close-range scanning, and larger for greater scan distance. A common guideline is a minimum size of scan distance ÷ 10. Always export at 300 DPI for print.

KoloQR generates codes in your browser - the code itself contains only the data you enter, and static codes point directly to your link with no tracking layer in between.

A rounded QR code keeps the square shape and only softens the modules - rounded corners or dots on each cell. A round (circle) QR code wraps the whole square grid in a circular frame, so its silhouette is a circle. Both scan the same way; the rounded version fits a square layout, the round one fits a surface that is already circular. In the generator, rounded corners are the Grouped rounded pattern and the circle is the Circular shape.
