How to Create a Professional QR Code

Follow these simple steps to design and generate your first QR code in seconds.

1. Step 1, Select Content Type

   Choose what the code holds — a website link, plain text, an email, a Wi-Fi network, a phone call, an SMS or a map location. Each type has its own fields.

   Note

   You can also browse our library of pre-designed templates for popular use cases to save time.

2. Step 2, Enter Details

   Complete the required fields based on your selected type. For instance, enter the target URL for a web link, or network ID and password for a Wi-Fi code.

   Note

   Verify that all information is 100% accurate, as this data will be encoded directly into your final QR code.

3. Step 3, Visual Customization

   Pick a style for your code from the Posty5 templates or from your own templates. A template sets the colors, the logo, the title, the dot size and the image size.

   Note

   This step is entirely optional; feel free to skip it and use the professional default design if you’re in a hurry.

4. Step 4, Generate & Download

   Save the code, then use Download on its card, on its details page or on the screen shown after you save it to get a PNG, a PNG for print, an SVG or a PDF. Download and print

   Note

   Pro tip, Always test your QR code with multiple scanning devices and apps before proceeding with high-volume printing or public distribution.

Choose static or dynamic

Pick Dynamic to be able to change where the code leads after you print it, or Static to put the content itself in the image. Dynamic is selected by default.

Note

Wi-Fi codes are always static.

Design your QR code

A QR code’s look comes from a template. Open Templates in the QR Codes menu, create a template, and pick it when you create or edit a QR code. The editor shows a live preview and a Scannability card next to its tabs.

• Size & quality - the image width and height in pixels, the error-correction level, and the border around the code.
• Colors - the dark and light colours, a Fill section that paints the code pattern in one colour or in a linear or radial gradient of two or three colours, a Transparent background option, and separate colours for the corner markers, the alignment marker and the timing lines.
• Shapes - the dot shape (square, rounded, dots, classy or extra rounded), the corner frame shape (square, rounded, circle or leaf), the corner centre shape (square, rounded, circle or diamond), and sliders for the dot size.
• Frame - seven frames around the code, from a title strip to a circle ring. Pick a call to action such as Scan for menu to fill the frame text in your language, or type your own text of up to 32 characters, then set the frame and text colours.
• Logo - upload a logo file, paste an image URL, or choose one from the logo library, then set its size and background. Uploading needs the Starter plan or higher and takes PNG, JPEG, WebP or SVG files of up to 2 MB. A pasted URL and the library work on every plan.
• Title - a text strip with its own colours, height and margin. It appears only for classic designs; with the new renderer, use the Title strip frame instead.

Classic and new designs

Choosing a shape, a fill, a transparent background or a frame moves the design to the new renderer, which draws those options. A note above the tabs then says the look may shift slightly, and the Logo tab gains Clear dots behind logo. Use classic renderer, in the same note, removes the new options and brings back the classic look.

Templates and QR codes you do not change keep their classic look.

Check scannability

The Scannability card next to the preview rates the design for the print size you pick and lists what to fix. It only warns, so you can always save. It checks the following.

• Contrast - warns when the code colours, including every gradient colour and corner colour, are too close to the background. Darken the code or lighten the background.
• Inverted code - warns when the code is lighter than its background, which some scanner apps cannot read.
• Logo size - compares the logo’s area with the error-correction level. It warns when the logo covers more than about 3% of the code at level L, 8% at M, 12% at Q or 15% at H, and rates it poor above 5%, 12%, 18% and 22%. Make the logo smaller or raise error correction.
• Margin - warns when the empty border around the code is narrower than 4 modules, and rates it poor under 2. A frame’s padding counts as margin.
• Module size - warns when each module would print smaller than 0.5 mm at the chosen print size, and rates it poor under 0.33 mm. Print larger or shorten the content.
• Dot size - warns when the Dot Size slider is below 0.7, and rates it poor below 0.5.

Note

The same card appears when you create a QR code, and in the PNG for print and PDF windows when you open them from a code’s details page. Download and print

Change where a printed code goes

With a dynamic code you change the content, not the image, so there is nothing to reprint.

1. Open the code

   In your QR codes list, choose Edit on the dynamic code.

2. Change the target

   Enter the new content. You can also change the type, for example from a website to a phone call.

3. Save

   The next scan of the printed code opens the new content.

Tip

Only dynamic codes can be changed this way. A static code needs a new image.

Counting Visits

Scanning a Posty5 QR code opens its content directly, so Posty5 never sees the scan. What a code’s details and its Analytics tab count is visits to its Posty5 page. To count scans of a printed code, print a short link’s QR image instead. How visit analytics work

Operational Best Practices

Follow these expert guidelines to ensure your audience enjoys a seamless, error-free scanning experience every time.

Visual Design Standards

• Prioritize Contrast - Use a dark foreground against a light background to ensure high readability for all camera lenses and lighting conditions.
• Keep Logos Small - Stay within the Scannability card’s limit for your error-correction level, which is about 15% of the code at level H and less at lower levels.
• Max Durability - Implement the highest Error Correction Level (Level H) when applying complex branding or dense color customizations.

Tactical Placement Guide

• Flat & Non-Reflective - Display QR codes on flat surfaces and use matte finishes to eliminate glare that can interfere with scanning.
• Scale for Success - Maintain a minimum size of 2x2 cm (0.8x0.8 in) for print items to ensure compatibility across all mobile devices.
• Strategic Visibility - Position QR codes at eye level and within natural traffic flows to maximize user engagement and interaction.

Pre-Launch Testing Protocol

• Multi-Device Verification - Scan your code using various smartphone models (iOS and Android) and different reader apps to guarantee universal compatibility before mass distribution.
• Content Link Integrity - Double-check that the embedded URL or data is correct and points precisely to the intended, live destination without technical errors.
• Environmental Light Stress-Test - If your code is deployed in physical spaces, test its scannability under diverse lighting, from direct sunlight to low-light evening environments.

Content & Conversion Strategy

• Strong Call-to-Action (CTA) - Always accompany your QR code with a clear verbal instruction (e.g., ‘Scan for Menu’ or ‘Claim Your Discount’) to significantly boost engagement rates.
• Mobile-First Destinations - Ensure your landing page is 100% responsive and optimized for mobile devices with fast load times.
• Content That Changes - For content that may change, such as a seasonal menu, encode a short link and change its destination instead of reprinting the code.
