Barcode Tools
Generate Barcode API Overview
The Generate Barcode API allows you to generate high-quality barcode images from provided payload. It supports a wide range of barcode formats, including 1D barcodes like Code 128, Code 39, EAN-13, and 2D barcodes like Data Matrix. You can customize the output image format (vectorial SVG, PNG, JPG, TIFF), set specific dimensions (width and height), adjust margins, and set image resolution. The API also provides an option to use recommended proportions for optimal readability and supports GS1 formatting standard.

Bool Default: FalseIf set to true, the barcode will be generated in GS1 format.
OutputFormat
Collection Default: svgThe format of the output image.
Values: svg png jpg tiffImageWidth
Integer Default: 600Image width in pixels.
Range: 10 .. 20000ImageHeight
Integer Default: 600Image height in pixels.
Range: 10 .. 20000ScaleProportions
Bool Default: TrueIf set to true, the barcode will be generated using recommended proportions based on the larger dimension.
ImageResolution
Integer Default: 200Set output image resolution in dpi.
Range: 10 .. 800Margin
Integer Default: 0The margin of the barcode image in pixels.
Range: 0 .. 1000StoreFile
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.
