How to Make QR Codes

QR codes are becoming an increasingly popular tool in today's digital age. QR codes are two-dimensional barcodes that can be scanned using a smartphone camera and a QR code reader app. They provide a convenient way to access information and are widely used in various industries, from marketing and advertising to healthcare and retail. QR codes provide businesses and individuals with a cost-effective, measurable, and versatile solution for sharing and accessing information.

QR codes have a much larger capacity for storing information compared to barcodes, allowing them to store more data such as URLs. If your need is to make very short texts machine-readable, a barcode generator will do the trick.

In this article, we'll show you how to make QR codes in a few simple steps.

QR code tips

In order to keep your QR codes recognizable and readable, here are some tips to keep in mind.

QR codes should be square

Image width and height should be equal. A perfect square makes your QR code easy to recognize by smartphones.

Background should be light

Code squares must be dark, and background must be light. If you think that inverting colors is a great design feature, think twice. It often makes QR codes unscannable.

Mind the contrast

Another important aspect of code readability is contrast. Make sure that your code stands out from the background.

How to create a QR Code for URL

For most QR codes, you may want to redirect users to a URL. In that case, enter the URL as a text, using Bulk QR Code Generator. When a user scans your QR code with a URL, the browser will open that address.

Ensure that your URL begins with either "http://" or "https://", even though many QR code reader apps can identify URLs without these prefixes.

QR codes with URLs are indistinguishable from QR codes containing any text. You can color freely as you wish, taking care not to impair readability.

• You can link any content type such as PDFs, VCF contact cards, and MP3 files. Links containing Microsoft Word, Excel, PowerPoint documents are also suitable for QR codes.
• You can link to any online form, including Google Forms, Canva, Typeform, Jotform.
• You can track the number of scans your QR code has received, by utilizing a web app or a URL shortening service such as bit.ly, cutt.ly, tinyurl. With measurable results, you can track conversions, and overall engagement with your customers. This data can be used to adjust your marketing strategies and improve the overall effectiveness of your campaigns.
• You can link to any website or mobile app (iOS and Android) to provide menus. QR codes can direct customers to a contactless online menu so they can order right from their phone. They also allow restaurants to instantly update menu items based on availability and pricing.
