Most generators give you a colour and a logo. QR Studio gives you the module shape, the eye frames, the eye pupils, a colour for each, a gradient across the whole code, and a preview of your real code while you work.
Design your QR code — free to start
A QR code is a grid of light and dark squares called modules. A scanner reads the grid, not the artwork, so as long as a dark module still reads as dark and a light one as light, you can draw the dark ones however you like — as circles, diamonds, leaves, hearts or joined-up bars.
Three squares in the corners are different. Those are the finder patterns, and a camera uses them to work out where the code is and which way up it sits. They follow a 1:1:3:1:1 ratio of dark to light across their width, and that ratio is what a scanner looks for. QR Studio lets you restyle them, but every shape in the picker keeps that ratio intact — which is why a rounded or circular eye still scans and a hand-drawn one usually does not.
Every decorative choice spends a little of the code’s error correction. Small dots leave more white between modules; a logo covers modules outright; a low-contrast gradient makes the camera work harder in poor light. None of that is a problem on its own, and all of it together is.
The studio keeps score for you. It raises a warning when contrast between the modules and the background drops too far, when a logo grows large enough to eat into the data at the error-correction level you picked, and when a combination is known to be fragile at small print sizes. The warnings are advisory — you can ship anyway — but they appear before you download, not after the poster is printed.
The safest habit is still the oldest one: download the real file, print it at the size you will actually use, and scan the paper with two or three different phones.
Downloads are vector SVG, so the code scales to a business card or a billboard without softening the module edges a scanner keys on. There is no watermark and no attribution on any plan.
The same design carries through to print-ready PDF artwork — module shapes, eye shapes, per-part colours, gradient and logo — separated for CMYK with bleed and crop marks, so what you designed on screen is what the press puts on paper.
What the feature actually does, part by part.
Squares, rounded, extra rounded, dots, small dots, diamonds, hexagons, crosses, stars, hearts, leaves, tiles and joined vertical or horizontal bars.
Ten frame shapes and nine pupil shapes, mixed freely. The frame stays exactly one module thick so the light separator a scanner needs survives.
The modules, the eye frames and the eye pupils each take their own colour, which is how a code picks up a two-colour brand instead of flattening to one.
Run a gradient across the modules at any angle, or out from the centre. Contrast is checked against the background as you go.
Drop in a PNG or SVG, size it, and sit it on a knockout plate so it never touches a module. Raise the error correction and the code reads through it.
Low contrast, an oversized logo and known-fragile combinations are flagged while you design, not after you have printed a thousand posters.
Anyone who has been told the QR code has to match the brand guidelines.
The preview renders your real code, not a stand-in, so what you see is what downloads.
Create the QR code first — the design is applied to a code that already has a destination.
Open QR Studio from the code’s menu on your dashboard.
Pick a module shape, then style the eye frames and pupils, and set a colour for each part.
Add a gradient or a centre logo if you want one, and watch the warnings panel as you go.
Download the SVG, or save the design as a brand template to reuse on other codes.
