A QR code is a scannable code that a phone camera can read. It can contain a website link, text, contact details or other information. Instead of asking someone to type a long URL or Wi-Fi details manually, you can let them scan the code to access the information. Common uses include: Sharing your website or online store on a business card, poster or product label. Making it easier for customers to contact you through WhatsApp. Helping guests connect to a Wi-Fi network by scanning a code. Sharing an email address, phone number or contact card. Sharing a location or place. Linking a resume to your portfolio or professional profile. ADAWATAI QR Code Studio lets you generate and customize the code in your browser, with a live preview before export. Step 1: Choose what your QR code should contain Start in the QR CONTENT panel. You will see nine content options. Choose the one that matches what you want people to access; the relevant input fields will appear after selection. Image 1: Choose the type of information people will access when they scan the QR code. 1. Website Choose Website to direct people to your website, online store, product page or portfolio. Enter the URL you want the QR code to open. 2. Text Use Text when you want the QR code to display a written message or a short piece of information instead of opening a website. 3. Wi-Fi Select Wi-Fi to enter your network name and password. People can scan the code to connect without typing the details manually. Privacy reminder: anyone who can scan a Wi-Fi QR code may be able to use the connection details encoded in it. Avoid posting it publicly if the network is intended for selected guests only. 4. WhatsApp Use this option to make it easier for customers or visitors to reach you through WhatsApp instead of manually saving and searching for your number. 5. Email Create a QR code that makes it easier for others to contact you by email. 6. Phone Put a phone number into the QR code so people can access it quickly after scanning. 7. Contact Choose Contact to create a code containing contact information. This can be useful on business cards and professional materials. 8. SMS Use SMS to create a code associated with a text message, based on the fields shown after you select this content type. 9. Location Choose Location when you want to share a place or geographic location through a scannable code. Step 2: Customize the QR code with colors and gradients After choosing the content, open DESIGN YOUR QR. This is where you can make the code match your brand colors or personal design style. Image 2: Visual design controls for your QR code. Quick color palettes The tool includes six quick palettes: ADAWATAI purple, ocean blue, forest green, sunset, monochrome and rose. Choose one as a starting point, then fine-tune the colors if needed. Primary and secondary colors Set the Primary and Secondary colors using the color pickers. These controls help you create a color treatment that fits your brand. Background and gradient direction You can enable or disable the background and choose its color. The gradient menu offers four directions: Horizontal. Vertical. Diagonal. Radial. Dot pattern and corner style Choose from five dot patterns: Square, Dots, Rounded, Classy and Soft classy. You can also choose the corner style: Sharp, Rounded or Dot. Reverse colors and pick from screen The interface includes Reverse colors and Pick from screen controls. The screen color picker depends on browser support. Step 3: Add your logo to the center of the QR code To give your QR code a branded look, open CENTER LOGO and upload an image from your device. Image 3: Live QR preview while customizing the design. The logo uploader accepts: PNG. JPG or JPEG. WebP. The maximum logo file size is 3 MB. After uploading, use the Logo size slider to adjust its size within the displayed range of 15% to 32%. The interface says that adding a logo automatically enables high error correction. Still, use a simple, small logo, keep the QR modules clear and test the code with your phone before sharing or printing it. Step 4: Set error correction, resolution and quiet zone Open QUALITY & EXPORT to adjust settings that help maintain scan reliability and output quality. Image 4: Error correction, resolution and quiet-zone settings. Error correction The tool displays four levels: Level Displayed percentage Note L 7% Low level. M 15% Medium level. Q 25% The default selection shown in the screenshot. H 30% High level. When you add a logo, the interface says a high error-correction level is enabled automatically. Resolution You can choose 512 × 512, 1024 × 1024 or 2048 × 2048 pixels. A higher resolution may be useful for larger layouts and print workflows, but always test the exported file after choosing your settings. Quiet zone The Quiet zone slider adjusts the space around the QR code within the displayed range of 14 to 36 pixels. Keep this surrounding area clear; do not place text or decorative elements too close to the code. Save, restore or reset your style Three controls help manage your design: Save style: save your current style. Restore style: restore the saved style. Reset design: reset the design settings. Step 5: Preview, copy, download and share your QR code The Your live QR panel displays a live preview. Review it whenever you change the content, colors or dot patterns. Image 5: QR preview and copy, download and share controls in a mobile-friendly layout. The tool also displays a contrast status to help you notice whether the design is suitable for scanning. Pay attention to this indicator if you choose light colors or gradients with similar tones. The available export formats are: PNG: suitable for most digital uses. SVG: useful for professional print and resizing because it is a vector format. JPG: a common image format. WebP: a modern image format that can help reduce file size. You will also see Copy PNG to copy the code, Download QR to save it, and Share to share it when your browser or device supports that action. Important: scan the QR code with your phone before printing. Test the downloaded file itself, not only the on-screen preview, and try more than one phone if possible. Advertisement How to use a QR code in your resume One useful way to use a QR code is to add it to your resume so a recruiter can quickly open your portfolio, personal website or professional profile. You could create a QR code that opens: Your online portfolio. Your LinkedIn profile. Your personal website or project page. An online version of your resume or professional profile. A practical way to add it to your CV Choose a public professional link you want to share, such as your portfolio or LinkedIn profile. Open ADAWATAI QR Code Studio and select Website. Enter the link and customize the QR colors to match your resume design. Download the code as PNG or SVG. After creating your resume, insert the QR image into the final document using a document or PDF editor that supports adding images. Add a clear label such as “Portfolio” or “LinkedIn”. Test the QR code from the final PDF and from a printed copy before sending your application. If you first want to create a well-organized resume, read our guide: How to Create a Professional Resume with ADAWATAI CV Builder. It explains template selection, design customization, and adding your experience, education and skills. Important clarification: QR Code Studio generates and downloads the QR image as a separate file. The supplied CV Builder interface screenshots do not show a dedicated QR insertion control, so add the downloaded image to your final resume using an editor that supports image insertion. Privacy and tips before sharing or printing The tool interface states that your QR content and logo stay in your browser, and that the code is generated on your device rather than uploaded to ADAWATAI servers. This is useful when preparing QR codes with information you do not want to send to an external service. However, remember that anyone who obtains the QR code can scan it. Keep these points in mind: Do not publish a Wi-Fi QR code publicly if you do not want everyone to access the network. Check the URL, phone number or contact information before downloading. Use strong contrast between the QR modules and background. Keep the center logo small and simple. Leave the quiet zone clear. Test the downloaded code before printing or publishing it.
