1 Overview

Boring and ugly old-school qr codeA QR code (or ‘Quick Response Code’) is a machine-readable optical label in the form of a matrix bar-code.

Smart-phones easily recognize and read such 2 dimensional bar-codes. QR codes may contain many kind of data: raw text but also internet address, GPS position, phone call, sms message, email and even geographic position on earth.

Some of these formatted contents may trigger events on smart-phones, like activating your web browser with a predefined internet address or pre-filling an email for you.

1.1 QR Code Elements

QRcodeLab - online qr generator - better qr code design with flower and ladybugsQR codes usually consists of black squares distributed on a squared grid.
But it’s also possible to look at it from a new perspective.

These severe-looking squares can come in a variety of patterns and colors in order to be more discreet and visually more pleasant.
To achieve this, lets separate the various elements that make up a QR code.

First, as we move on from a black and white square world to a more graphic and colorful one, we will now talk about light and dark elements, targets, dots and logo.

1.1.1 Background

Think of it as a safe quiet zone around and beneath the QR code, of uniform color. This is recommended for a safe QR code scanning and decoding.

Your background may take different forms. Also, depending of the image you place your QR code on, you may decide to have a more or less visible background – or even no background at all, depending of your ground image.

Some examples: QRcodeLab - online qr generator - different possible qr code background forms

1.1.2 Targets

Targets are sets of concentric strips alternately dark and light. Those strips are usually squared but can adopt many patterns.
Why target? Because they’re used as finder elements, as well as they help to define the position, orientation and alignment of the matrix bar-code. Broadly speaking, they do not contain data but are safeguards to locate and read the QR code data.

QR codes always have 3 big targets and one (or more, depending on the quantity of data) small target. Targets have 3 concentric stripes: dark-light-dark. Big targets may show an additional light strip as they are located near the edge and QR codes need a light quite zone for optimal decoding. We need some minimal contrast to have the target pattern recognized.

Targets can take many different forms, like: QRcodeLab - online qr generator - different qr code targets forms design examples

1.1.3 Dots

With the dots, you’re at the heart of the QR codes’ content. The positions of the dots will determine the technical parameters as well as the encoded content of your QR code.

Dark dots usually represent the data. Light dots help recognize dark dots, especially in case the background image is also dark or there are dark spots. We need some minimal contrast to have the dots pattern recognized.

Dots can take many different forms. Some examples:QRcodeLab -  online qr code generator - different qr code dots forms design examples

QRcodeLab - online qr generator - qr code stars and owlA QR code can host an extra-layer for you to add a logo or a small image over it.

A logo image can overlap a small portion of a QR code. Don’t make it too large as the QR code won’t be readable anymore. Also, a logo image must never hide a target element! Check our blog on how to add a logo to a QR code and what to avoid.

3.2 Config File

QRcodeLab - online qr generator - configuration files panelOnce registered and log in the application, access to this menu entry is unlocked, so you can start working with configurations files.

A configuration file stores all the elements and parameters necessary for the design of a QR code or a QR image: the content of the QR code, the parameters of its components, its position and orientation including the 3D effects, the logo with its own settings as well as the associated ground image.

You can download and upload such a file and/or share it with other users of the QRcodeLab QR generator. We also provide a gallery of examples for your inspiration, which you can choose to use.

3.2.1 Load

This entry displays a standard pop-up window to download a file from your device.

QRcodeLab - online qr generator - configuration files gallery examples pop-up windowsGet access to a gallery of sample configuration files through this menu entry. Click on any image to load the corresponding configuration.

Once the process is complete, an exact copy of what you chose shows up in your viewing area, which you can then modify at your convenience.

3.2.3 Save

QRcodeLab - online qr generator - configuration files download listWell… make sure to regularly save your work and your graphic compositions so that you don’t lose your work if something goes wrong. Also, this allows you to resume your work later in case of an interruption. You may as well choose to share it with other users of the application.

A list of configuration files is provided, showing all the configurations saved during your working session, including the latest one. They are sorted in date order, from the most recent to the oldest. Just click on the download button to create a local copy of your work on your device.

3.3 Dynamic QR

QRcodeLab - online qr generator - dynamic tracking code management panelThe dynamic qr code menu entry is available if you have a currently valid paid subscription. You’ll get access to a management console for your dynamic codes, along with a set of associated functions.

The upper part of the pop-up window displays a search field to narrow down the list of dynamic codes. On the right side a gauge displays the amount of dynamic codes still available in your subscription.

Dynamic codes are listed from newest to oldest. For each code the ‘Id’ and ‘Final URL’ values are active links for you to check the redirection process and the final destination. On the right side you’ll find 4 buttons to manage your codes:

  • Edit: allows you to change the title and the destination address of your code.
  • Pause: to suspend your dynamic code. Access to the final destination is no longer available and data is no more collected. You can choose to resume at a later time.
  • Delete: well… it removes the dynamic code with no way back, including the associated statistical data.
  • QRcodeLab - online qr generator - dynamic tracking code analytics dashboardAnalytics: this one opens a dashboard for a visual display of the dynamic code’s statistical data. Choose a time frame and filter the dashboard by anything you click on. The top graph displays the following dimensions : unique visitors, page views, bounce rate (% of sessions with only a single page view), and visit duration. You can break down the data by months, weeks, days and hours according to the time frame selected. The following graphs ‘Top Sources’ and ‘Top pages’ are limited to the final URL of the dynamic code. ‘Location’ and ‘Devices’ graphs give insights into the geographical origin (country, region, city) and the type of device (by screen size, web browser or device operating system) of who scans your dynamic/tracking code.

In the event you choose to downgrade your subscription, or even to switch to free mode, all or part of your dynamic codes could be disabled. This is because each subscription handles different quantities of dynamic codes, and the free mode does not. In such a case, the excess codes will be paused (not deleted) and the current data kept. This mandatory procedure is applied by order from the oldest, and the user can refine this choice later within the subscription boundaries.

3.4 Downloads

QRcodeLab - online qr generator - file download management panelThis menu entry gives access to an interface for managing the files generated in the current work session. These can be qr images (tab ‘IMAGES’ on the left) or configuration files (tab ‘CONFIGS’ on the right). The files are listed from most recent to oldest. The internal name of each file reflects the date it was created.

These files are temporarily saved in the internal memory of the web browser (or the App) and disappear when you log out, close the web page or quit the browser (or the App). For as long as you stay in your working session, you have access to your files. We do not store any of your documents on our servers.

QRcodeLab - online qr generator - tools panelYou are now getting at the heart of our app. All the design tools are located in this panel.
We’ll make a top-down description.

5.1 Interaction Modes

The Qrcodelab online QR code generator provides three user levels for a better working experience and spare your time:

  • Dobby’ (simpler interface, basic controls),
  • Padawan’ (intermediate level), or
  • Jedi’ (full control on all settings).

Switch from one mode to another to accelerate your design process.
First, use the ‘Dobby’ mode to define your settings globally. Then dive more into details with the ‘Padawan’ mode and finish, if needed, with the advanced ‘Jedi’ mode.

These interaction levels affect the scope of the tools in the tools panel.

5.2 QR Content

QRcodeLab - online qr generator - content widgetThis drop-down widget will let you define the content of your QR code. Depending on the length of your data, the QR code appearance and size may change.

Our QRcodeLab online QR code generator allows you to define many kind of content:

  • Text: raw text, write down whatever you want!
  • URL: this is an internet address. Not only a website address but also the trailing path and even the tracking code (if you plan to monitor a publishing campaign). Depending on the device on which your code will be read, this may trigger an event that will open a web browser with the url you defined.
  • SMS: this stands for ‘short message service’. You’ll be able to define a destination phone number and a short text message. Depending on the device on which your code will be read, this may trigger an event that will open a messaging app with your predefined data.
  • Call: use this option to drive someone to initiate call. Depending on the device on which your code will be read, this may trigger an event that will open the telephone app, pre-dialing the phone number you defined.
  • Email: here you can prepare an email with the target email address, a subject line and a text message. Depending on the device on which your code will be read, this may trigger an event that will open an email application with the predefined email.
  • Geographic: specify a geographical position with latitude, longitude and altitude. Depending on the device on which your code will be read, this may trigger an event that will open a map application spotting your predefined location.
  • Google Maps: specify a Google Maps location. Use the provided link and follow instructions to get the link location and then paste it in the URL field.
  • Wi-Fi: encode a Wi-Fi network ID, authentication method and credential into a QR code.
  • Google Play Store: link to an android app on Google website. Use the provided link to search for the desired app and then copy/paste the app link in the URL field.
  • Apple Play Store: link to an IOS app on Apple website.

QR code contents are editable only if you’re authenticated and have a valid subscription plan!

5.2.1 Content for Dynamic QR Code

Some specific kind of QR code content may show up a toggle switch to activate the dynamic and tracking code functionalities, these are:

  • Web addresses (URL)
  • Google Maps
  • Google Play Store
  • Apple App Store

QRcodeLab - online qr generator - toggle switch to activate a dynamic QRIn such a case a ‘Dyn QR’ entry shows up, and you may choose to generate a dynamic and tracking QR code associated with a short URL. Simply turn on the toggle switch and some additional data will appear below:

  • QRcodeLab - online qr generator - ddynamic QR settingsTitle: a name has been set for your new dynamic/tracking code. By default, it’s ‘New dyn QR’. It can be modified later in the dynamic QR management console (refer to the matching entry of the left interface panel).
  • Id: it’s a code that’s unique, made up of a series of numbers and letters that you can’t modify. It’s a subset of yor short URL, like this example: ‘https://s.dynqr.co/a9m0z’
  • Target: the data you provided has been moved to this field and replaced by a unique short URL. Like the tile, it’s editable in the management console.

QRcodeLab - online qr generator - dynamic tracking code list panelEventually, the ‘List’ button allows to reach your collection of dynamic/tracking codes in case you wish to work with an existing one.
Note that any code labeled ‘New’ for the purpose of creating a QR code is not yet editable. You will be able to do so in the dynamic QR management panel once the QR image is generated.
