Why has Adobe not seen it fit to include a QR code generator in Illustrator? Currently, getting QR code "images" into Illustrator is a pain in the a##. Adobe please wake up.
On the mac there is a small app available which you just run, paste in your url and it opens a vector QR code in Illustrator (CC too), ready for anything.
I use this web app to make QR-Codes, which you also can download as a vector file (for the vector file you have to be logged in).
It's the best QR-Code generator I know.
I do wonder why there is not a generator included in Illustrator, something to do with intended/expected use maybe.
You can quite easily generate a QR code in inDesign and then either copy/paste or drag/drop the matrix image into Illustrator from there, obviously this is a better workflow if you regularly use inDesign but the option is there.
If you have the Creative Cloud account and Illustrator 2014 CC and a Mac, I'd recommend this one. You can get it off the Adobe Add-Ons.
QR Code Maker
Check out QR Code Pro by Scanova. Its available for Creative cloud users currently for versions CC and CC 2014. Although its not free but they provide a free trial for 30 days.
Soooo, sticking to the Adobe suite for QR codes goes a little something like this:
1. Start up InDesign.
2. Make some lame layout like a blank letter page.
3. place a content box on the page.
4. Access the menu along the top and select "Object>Generate QR Code...".
5. It will generate your QR Code inside the content box.
6. Click once on the center of the content box in order to select content, not the container itself.
7. press "cmd/ctrl + c" to copy content.
8. Start up Illustrator.
9. open target document.
10. Press "cmd/ctrl + v" to place QR Code. Adobe's generated codes are already vectored. You can you the pathfinder to reduce the number of objects placed.
It would be nice if Adobe Illustrator had its own QR Code generator (as well as a barcode generator and validating tool for both QR codes and barcodes). One of Adobe's rivals, CorelDRAW X7 has a QR Code and barcode generating capability. I've used the QR Code generator in InDesign; it works alright, but doesn't have nearly as many features as the one in CorelDRAW X7.
If Adobe Illustrator is going to incorporate a QR Code generator I'd like to see one with more custom options, such as true incorporation of logos or images in part of the code. Most QR Code generators will make the code with a certain amount of error correction. That can allow you to place a simple icon (or true logo) in the middle of it at a small size and still leave enough valid code visible for it to work. But it seems like a kludge to simply flop artwork directly over bits of QR Code data. Why not make a QR Code generator that makes bits of code flow around the icon in the center? That would be a lot more cool and useful. I don't think any of the other QR Code generating tools out there can do that. So it would be an opportunity for Adobe to one-up the competition.
if you need universal QR code generator for Illustrator you can use a special script that generates qr code with Symbols and Layers
as you can see in this picture.
Also max 30% of the QR Code space can be occupied by your logo or picture.
I found this thread while searching for something else. Thought I'd leave an updated solution - InDesign makes QR Codes. You can add them to your library from Indesign, and / or copy paste to Illustrator / Photoshop etc.
