Barcode Tools
Scan QR Code Node.js Overview
Scan QR Code NodeJS package detects and decodes QR codes from PDF documents, scanned files, and even photographed QR codes in various image formats (PNG, JPG, TIFF). You can enable multiple barcode detection, try intensive detection algorithms, and handle inverted or rotated barcodes. The result is returned as JSON with decoded values and optional metadata.

Customizable Parameters
Fine-tune your automation with these powerful conversion options
File
File Supported formats: .pdf .png .jpg .tiffFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected PDF.
PageRange
String Default: 1-2000Set PDF page range to convert. Example 1-10 or 1,2,5.
DetectMultiple
Bool Default: FalseIf set to true, the converter will attempt to detect multiple barcodes.
EnhancedDetection
Bool Default: FalseIf set to true, the converter will use more intensive algorithms to detect barcodes.
IncludeInverted
Bool Default: FalseIf set to true, the converter will also try to detect barcodes with inverted colors.
AutoRotate
Bool Default: FalseIf set to true, the converter will automatically rotate the view to detect barcodes.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
