It looks like a monochrome pixelated image , but the QR codes hide behind from a web link to your WiFi code, a file, a YouTube video or your current location. Any information or content that you want to share is within the reach of a pixelated code. So popular are they that your Android phone and iPhone can scan them directly from the camera app and tell you what's behind that pixelated code.
Scanning QR codes is very easy. And what about creating them? The good news is that it is also something that anyone can do and in a few seconds. Free of charge and from any device connected.
You can create your own QR codes from Google Chrome and derivatives such as Brave, Opera, Vivaldi or Edge, also using mobile applications for this purpose. And on the internet there are many web pages that integrate their own generator of codes. Easy to use, without the need to register and compatible with any type of content that can be shared online. But let's get down to business: how to create QR codes from any browser on any device.
Generate QR codes, free and online
QR-Codes is one of many websites that allow you to create QR codes for free, from your web browser. It does not matter if you access from your computer, a tablet or a smartphone. The page loads the same since it is very simple and efficient.
Using it is no secret either. First, we choose what we want to share through the code generated by ourselves. It can be a link to a web address, an SMS message, a phone number, an email with your address, subject and message, a text of up to 160 characters, a vCard contact card, your location on the map using latitude and length, a calendar event or your WiFi address.
The second step consists of customizing the appearance of that code , in size and complexity. It can be small, medium or large, very small or very large. And decide the complex of the code: low, medium, high or very high. Finally, click on the button Generate QR code and voila, we will obtain a personalized code following the instructions that we have previously configured.
This generated code is free, you can use it in any context , personal or professional, and it does not expire. Come on, that will continue to work for years as long as you have a QR code reader handy. As for the content linked or encoded in the code, if you want to change it you will have to use dynamic QR codes . Later we will explain what they consist of and how to make them yourself.
Share your own codes
What do we do with that QR code generated with QR-Codes ? You can print it, save it on your device in image format, add it to another image, document or content, share it on social networks or instant messaging such as WhatsApp or Telegram … In short, you can do whatever you want with it. And if you want to insert it in your blog or web page, you can use the permanent link in HTML format instead.
You also have a third option to share the generated code. It consists of creating a dynamic QR code , that is, a pixelated code whose destination content can be changed to reuse the same code that we have previously created. It will be very useful to offer renewed content with the same code that you have printed or placed in a fixed place. So you will not have to change the QR code constantly.
Based on the recommendations of the QR code generator that we have used above, it is best to share that code in black and white and without frills. But if there is no other option, you can integrate it into more complex images and provide the color code . Of course, make sure there is a contrast between the generated code and the background. This will make it easier to read and decode it . In that sense, you can also play with the size of the code, which you can customize when creating it with the generator of QR-Codes .
