What Is a Bulk QR Code Generator?
A bulk QR code generator creates multiple QR codes from a list of URLs in a single batch operation, eliminating the need to generate each code one at a time. This tool processes up to 100 URLs simultaneously, applies your chosen size, color, and error correction settings to every code, and packages the results into a downloadable ZIP file. All processing runs in your browser using JavaScript and the qrcode.js library, so no data leaves your device.
Bulk generation is essential for businesses that need QR codes at scale. Manually creating 50 or 100 codes would take hours; this tool completes the same task in seconds. The output uses the PNG image format at your selected resolution, and each file follows a sequential naming convention like prefix_001.png through prefix_100.png for easy sorting and identification.
How to Generate Bulk QR Codes
Follow these five steps to create and download multiple QR codes at once.
- Enter URLs: Paste your list of URLs in the text area, one URL per line (maximum 100). Each URL becomes a separate QR code.
- Customize settings: Adjust size (128px to 512px), foreground and background colors, and error correction level to match your needs.
- Set filename prefix: Choose a prefix for your QR code files (e.g., "product", "event", "link"). Files are named prefix_001.png, prefix_002.png, and so on.
- Generate: Click "Generate QR Codes" to create all QR codes at once. A progress bar tracks the batch.
- Download ZIP: Download all generated QR codes as a single ZIP file using the JSZip library.
Bulk QR Code Examples
Here are practical scenarios showing how businesses use bulk QR code generation.
- E-commerce product catalog: An online store with 80 products pastes all product page URLs, sets the prefix to "product", and generates 80 QR codes. Each code is printed on the corresponding product packaging, linking customers directly to reviews, manuals, or reorder pages.
- Conference session links: A conference organizer generates QR codes for 30 session feedback forms. Each code links to a unique Google Form. The codes are printed on table cards at each session room so attendees can submit feedback by scanning.
- Restaurant multi-location menus: A restaurant chain with 12 locations generates QR codes for each location's menu page. The prefix "menu" produces files like
menu_001.pngthroughmenu_012.png, which are printed and laminated for each table. - Real estate listing flyers: A real estate agency generates QR codes for 25 active property listings. Each code links to the property's virtual tour page and is printed on "For Sale" signs and brochure inserts.
Best Practices for Bulk QR Codes
- Use URL shorteners for long links: Shorter URLs produce simpler QR codes with fewer modules, making them easier to scan at smaller print sizes. Services like Bitly or TinyURL reduce URL length before bulk generation.
- Test before printing: Always scan a few sample codes from your batch before sending them to print. Verify that colors, size, and error correction produce reliably scannable codes.
- Maintain a 4:1 contrast ratio: Dark foreground on light background is the universal standard. Avoid light-on-dark or low-contrast color combinations that may fail on older scanners.
- Choose Medium or High error correction for print: Printed materials may get scratched, folded, or partially covered. Medium (15%) handles minor damage; High (30%) tolerates significant obstruction.
- Include a quiet zone: Leave at least 4 modules of white space around each QR code when placing them in your design. This border helps scanners distinguish the code from surrounding graphics.
- Track with UTM parameters: Append UTM parameters to your URLs (e.g.,
?utm_source=qr&utm_campaign=catalog) before bulk generation so you can measure scan rates in Google Analytics.
Bulk QR Code Use Cases
- Product catalogs: Generate QR codes for all products in your inventory linking to details, manuals, or warranty registration.
- Event tickets: Create unique QR codes for multiple event attendees for check-in verification.
- Marketing campaigns: Generate QR codes for different landing pages or tracking URLs with UTM parameters.
- Digital menus: Create QR codes for multiple restaurant menu sections or items across locations.
- Real estate listings: Generate QR codes for property listings or virtual tour pages on signage.
- Conference materials: Create QR codes for session schedules, speaker profiles, or resource downloads.
- Classroom worksheets: Teachers generate QR codes linking to video explanations, quizzes, or supplementary reading for each assignment.
Frequently Asked Questions
You can generate up to 100 QR codes in a single batch. Enter one URL per line in the text area, and the tool will create a separate QR code image for each URL. All QR codes are generated directly in your browser using JavaScript, so there is no server-side limit or upload required.
All QR codes are exported as PNG image files inside a single ZIP archive. Each file is named using your chosen prefix followed by a sequential number, for example
qrcode_001.png, qrcode_002.png, and so on. PNG format ensures crisp edges at any print size.Error correction determines how much of the QR code can be damaged or obscured while remaining scannable. Low (7%) is fine for digital screens. Medium (15%) is the default and works well for most printed materials. Quartile (25%) and High (30%) are recommended when the QR code may be partially covered, such as on outdoor signage or products that may experience wear.
Yes, you can customize both the foreground (dark modules) and background colors for all QR codes in the batch. The same color settings apply to every QR code generated. Ensure sufficient contrast between foreground and background colors so scanners can reliably read the codes. A contrast ratio of at least 4:1 is recommended.
All QR code generation and ZIP file creation happens entirely in your browser using client-side JavaScript. No URLs or data are transmitted to any server. Your URL list stays on your device throughout the entire process, making this tool safe to use with confidential or sensitive links.
For printed materials, choose 256px or higher. A general rule is that the printed QR code should be at least 2 cm x 2 cm (about 0.8 x 0.8 inches) for reliable scanning. For large format printing like posters or banners, use 512px to ensure sharp output. For digital-only use such as emails or websites, 128px to 256px is typically sufficient.
