QR Code Generator Actor An Apify Actor that generates customizable QR codes with support for bulk generation, custom styling, and logo overlays. ## Features - ✅ Generate QR codes for URLs, text, WiFi credentials, or any string content - ✅ Bulk generation - Generate multiple QR codes in a single run - ✅ Custom colors - Customize dark and light module colors - ✅ Multiple formats - Output as PNG (base64 data URL) or SVG - ✅ Logo overlay - Add your brand logo to the center of QR codes - ✅ Error correction - Automatic high error correction when using logos - ✅ Flexible sizing - Customize QR code and logo dimensions ## Input The Actor accepts the following input parameters: | Parameter | Type | Required | Description | Default | | ---------------------- | ------- | -------- | ------------------------------------------------------------------------ | ------------------ | | content | array | ✅ | List of strings to encode as QR codes (URLs, text, etc.) | ["https://example.com"] | | format | string | ❌ | Output format: png or svg | png | | size | integer | ❌ | Width and height of the QR code in pixels (50-2000) | 300 | | colorDark | string | ❌ | Color of dark modules (hex format) | #000000 | | colorLight | string | ❌ | Color of light modules (hex format) | #ffffff | | errorCorrectionLevel | string | ❌ | Error correction level: L (7%), M (15%), Q (25%), or H (30%) | M (auto H with logo) | | logoUrl | string | ❌ | URL of a logo image to overlay on the QR code | - | | logoWidth | integer | ❌ | Logo width in pixels (defaults to 15% of QR code size) | - | | logoHeight | integer | ❌ | Logo height in pixels (defaults to 15% of QR code size) | - | ### Input Example json { "content": [ "https://example.com", "https://apify.com", "mailto:hello@example.com" ], "format": "png", "size": 400, "colorDark": "#1a237e", "colorLight": "#e8eaf6", "errorCorrectionLevel": "H", "logoUrl": "https://example.com/logo.png", "logoWidth": 60, "logoHeight": 60 } ## Output The Actor saves results to the default dataset. Each item in the output contains: | Field | Type | Description | | ------------------ | ------ | --------------------------------------------------------------- | | originalContent | string | The original input content that was encoded | | qrCodeDataUrl | string | Base64-encoded PNG data URL (when format is png) | | qrCodeSvg | string | SVG markup string (when format is svg) | ### Output Example json [ { "originalContent": "https://example.com", "qrCodeDataUrl": "data:image/png;base64,iVBORw0KGgoAAAANS..." }, { "originalContent": "https://apify.com", "qrCodeDataUrl": "data:image/png;base64,iVBORw0KGgoAAAANS..." } ] ## Usage Tips ### Logo Overlay When using a logo overlay: - The error correction level is automatically set to H (High - 30%) for better scannability - Logos are automatically sized to 15% of the QR code dimensions (customizable via logoWidth/logoHeight) - A white background is added around the logo for better contrast - Supported logo formats: PNG, JPG, SVG ### Error Correction Levels - L (Low) - ~7% error resistance - Best for clean, controlled environments - M (Medium) - ~15% error resistance - Good general-purpose level - Q (Quartile) - ~25% error resistance - Better for outdoor use - H (High) - ~30% error resistance - Required for logos, best for damaged/dirty conditions ### Bulk Generation To generate multiple QR codes in one run, simply add multiple strings to the content array: json { "content": [ "https://example.com/product1", "https://example.com/product2", "https://example.com/product3" ] } Each QR code will be saved as a separate item in the dataset with its originalContent for easy identification. This reads input from storage/key_value_stores/default/INPUT.json and saves output to storage/datasets/default/. ## Resources - Apify Platform - Apify SDK Documentation
