Frequently Asked Questions

Yes, QR Code Builder is 100% free to use. You can create unlimited QR codes with full customization options, download them in PNG or SVG format, and use them for any purpose — personal or commercial. There are no hidden fees, premium tiers, or sign-up requirements.

No, you do not need to create an account. QR Code Builder allows anonymous QR code generation without any registration. Simply visit the site, choose your QR code type, enter your content, customize the design, and download — all without signing up.

QR Code Builder supports 8 types of QR codes: URL (website links), Plain Text, WiFi network credentials, vCard (contact information), Email (with pre-filled subject and body), Phone numbers, SMS messages, and Geographic locations. Each type has dedicated input fields optimized for that content.

Absolutely! You can customize foreground and background colors, choose from multiple dot shapes (square, rounded, dots, classy, classy-rounded, extra-rounded), customize corner square shapes and corner dot shapes. You can also choose from pre-designed templates for a professional look.

QR Code Builder supports PNG and SVG file formats. PNG is ideal for digital use and printing at fixed sizes, while SVG is a vector format that scales to any size without losing quality, making it perfect for large prints, billboards, and professional design workflows.

You can download QR codes in multiple sizes: 256x256, 512x512, 1024x1024, 2048x2048, and 4096x4096 pixels. For most digital uses, 512px or 1024px is sufficient. For high-quality printing, we recommend 2048px or 4096px. SVG format provides unlimited scaling.

No, static QR codes generated by QR Code Builder never expire. The QR code data is encoded directly into the pattern, so it will work forever as long as the linked content (such as a website URL) remains active. There is no time limit or scan limit.

Static QR codes encode data directly in the QR pattern and cannot be changed after creation. Dynamic QR codes use a redirect URL that allows you to change the destination, track scans, and gather analytics without reprinting the code. QR Code Builder currently supports static QR codes, with dynamic QR codes planned for a future update.

Yes, all QR codes generated with QR Code Builder can be used for commercial purposes without any restrictions. You can use them on business cards, marketing materials, product packaging, restaurant menus, event tickets, and any other commercial application.

To create a WiFi QR code: 1) Select the "WiFi" type from the QR code type selector. 2) Enter your network name (SSID). 3) Enter your WiFi password. 4) Select the encryption type (WPA/WPA2, WEP, or None). 5) Optionally mark if the network is hidden. 6) Customize the design and download. When scanned, the QR code will automatically prompt the user to connect to your WiFi network.

To create a vCard QR code: 1) Select the "vCard" type. 2) Fill in contact details including first name, last name, phone number, email, company name, job title, website, and address. 3) Customize the QR code design. 4) Download and print. When scanned, the QR code will prompt the user to save the contact information directly to their phone.

QR Code Builder uses the highest error correction level ("H") by default, which can recover up to 30% of damaged data. This means your QR codes will still scan reliably even if partially covered, slightly damaged, or printed at lower quality. This is especially important for printed QR codes exposed to wear and tear.

Yes, QR Code Builder offers a bulk generation feature. You can upload a CSV file containing multiple entries, apply consistent styling across all codes, and download them all as a ZIP file. The bulk tool supports up to 100 QR codes per batch, ideal for inventory management, event ticketing, and marketing campaigns.

Yes, QR Code Builder provides a REST API for programmatic QR code generation. The API supports all QR code types, customization options, and output formats. Visit the API Documentation page for details on endpoints, parameters, and code examples in multiple programming languages.

Yes, we take privacy seriously. QR codes are generated client-side in your browser whenever possible, meaning your data never leaves your device. For server-side operations (like SVG generation), data is processed temporarily and never stored. We do not track, log, or store the content of your QR codes. See our Privacy Policy for complete details.

If your QR code is not scanning: 1) Ensure sufficient contrast between foreground and background colors. 2) Make sure the QR code is printed or displayed at an adequate size (minimum 2cm x 2cm for close scanning). 3) Check that the "quiet zone" (white border) around the code is not cropped. 4) Verify the encoded content is valid (working URL, correct WiFi credentials, etc.). 5) Try scanning with a different device or QR reader app.
