Introducing QR Factory 3, a modern QR code generator for macOS and iPadOS. Rebuilt in Swift with a redesigned interface, it provides an efficient workflow for creating QR codes for both individual and larger projects.

Download QR Factory 3 from the App Store to start a free 7-day trial. After the trial, continue with a subscription or choose a one-time purchase. An Enterprise Edition is also available for MDM deployment or for those who prefer a standalone, one-time purchase option.

QR Factory 3 supports the creation of unlimited QR codes entirely on-device. Codes are never hosted by Tunabelly Software and remain under full ownership and control of the user. QRD files make it easy to organize, edit, and move work between devices.

Batch generation is supported using CSV files, and the app includes templates for Avery and DYMO labels for accurate grid-based printing. Exporting is flexible, with options for PNG, TIFF, PDF, and EPS formats, as well as rotation and colorspaces such as RGB, CMYK, and Grayscale.

For macOS workflows, a full Command Line Interface is available.

Avery Label Support

We listened and delivered an incredible new feature in QR Factory 3 - layout the QR codes to print onto labels from Avery & DYMO.

Using the multiple codes feature, choose the label number that will be used and it will generate a multi page PDF with all the QR codes laid out exactly to the template.

Need specific sizing? Add custom dimensions if your desired size isn't in our extensive pre-set list.

Export Formats

QR Factory has support for many of the file formats needed for professional agencies including:

PDF & EPS* for vector formats
PNG & TIFF* for bitmap formats
RGB, CMYK and Grayscale color spaces
Export up to 4096 x 4096 pixels for bitmap formats
Optional rotation in 90° increments to help with certain layout requirements

* These formats are only available on the macOS version due to lack of native support on iPadOS. We're working on adding these in a future update.

Command Line Tools

On macOS, QR Factory can be launched via the command line to generate single or multiple QR codes. All the features that are normally available are also provided through the CLI. It even supports the standard input and output streams for redirecting the generated QR codes, or providing the content from another tool.

Time-Saving Tools

In addition to the professional features in QR Factory 3, we've also included the following abilities (click on the tabs to the right to view them) to help increase productivity.

Auto Verification

QR codes are continuously scanned to ensure that they are readable by a real user. The result of the verification is shown below the code.

As well, it also will monitor the reliability level when a middle icon/logo is used and adjust it accordingly.

Translations

Not everyone speaks English, so we added translations for the following languages:

QRD File

The entire app state can be saved into a snapshot, called a QRD file. This can be opened later to make changes to a QR code design without having to start over.
