QR Code PNG Format

A QR code generator will allow you to export your QR code in both PNG and SVG formats. The PNG format has special characteristics that you need to check before going for it.

For a start, PNG stands for Portable Network Graphic and is a compressed file that can handle 16 million colors while remaining small and handy —it is perfect for images with a transparent or a semi-transparent background.

Its lossless compression feature prevents it from losing quality every time it’s saved and opened.

QR Code PNG vs SVG Format

When exporting your newly-created QR codes, you face a transcendental decision: you want them as PNG images or in SVG format.

However, there are essential differences to bear in mind when exporting your QR code in either format. Let’s have a look.

PNG images are small in nature and are capable of very decent resolutions. However, if you expand them too much beyond their tight limits, you could end up with a code that no mobile phone —or any other QR code scanner— could scan.

On the other hand, SVG files are larger as they are vector-based. This means they are a complex mathematical network of lines, dots, shapes, and algorithms, which allows them to expand to bigger sizes without affecting their resolution.

When to Export QR Codes in PNG Format

Web

If you want to utilize your QR code on the internet —let’s say, have people scan your code on a screen— PNG codes are the best bet. Since you don’t need to print the code in big sizes, PNG codes will do the job as they only need to fit a screen.

Social Media

You can export to PNG all the social media codes you want to generate —a QR code for Instagram, for instance. This format is very convenient as it will ease the upload process given its size and lossless properties.

Small Prints

Indeed you can print a code in PNG format as long as it is in a small size. This means you can use this format for small billboards or posters, as well as print it on the back side of books, and on business cards.

How to Do the QR Code PNG Format Right

Given the specific properties of the PNG code, there are some elements you need to consider to make it functional. Not following these recommendations might result in a smartphone not being able to scan the code.

Size

Yes, size matters in this case. Too big a PNG code and quality will suffer and make it impossible to scan, whereas if it’s too small scanning devices will find it hard to pick it up.

In this sense, the minimal size is 1.2 inches or 32×32 millimeters. Be careful with the size since the wrong measurements could spoil a whole marketing campaign.

Color composition

As a rule of thumb —to make a code scannable— the background should be clearer than the dots and the marker center and border —graphic elements.

Low contrast between the foreground and background could make the code unreadable, so think of the color combination very carefully.

Call-to-action

QR codes are attractive devices that call your attention from distance. But it is necessary to include a call-to-action to prompt potential users to scan it. They hence will know what they should do with the code even if it’s self-explanatory!

FAQs

When should I use QR codes in PNG format?

PNG formats are perfect for online use and small prints. If you need large prints of a code you should go for the SVG format as it can be modified in Photoshop, Illustrator, and InDesign.

SVG formats allow lossless enlargement that is far superior to that of PNG files. They’re perfect for big banners or posters so users can scan from distance —they are heavier than the PNG format.

Wrap-Up

Knowing which format to print your QR code is absolutely important, and will spare you headaches in your marketing efforts or day-to-day use. The wrong type could mean a code that is not scannable, while the wrong color combination when creating it on the editor can also spoil the code’s readability.
