What barcode formats are supported?

The tool supports multiple barcode formats including CODE128 (alphanumeric), EAN13 (13-digit product codes), UPC-A (12-digit product codes), and other common formats. Select the format that matches your needs. CODE128 is most flexible (supports letters and numbers), while EAN13 and UPC-A are for numeric product codes.

What's the difference between CODE128, EAN13, and UPC-A?

CODE128 supports alphanumeric content (letters and numbers) and variable length. EAN13 is for 13-digit product codes (European Article Number). UPC-A is for 12-digit product codes (Universal Product Code). Use CODE128 for custom content, EAN13/UPC-A for standard product codes.

Can I use these barcodes for commercial products?

Yes, but ensure you use correct format and valid codes. EAN13 and UPC-A require valid product codes with check digits. For commercial products, you may need registered product codes. CODE128 can be used for custom internal tracking. Always verify barcode scans correctly before production use.

What resolution should I use for printing?

For printing, use at least 300 DPI (dots per inch) resolution. The downloaded PNG image can be scaled, but ensure final print size maintains sufficient barcode width for scanning. Barcodes should be at least 1 inch wide for reliable scanning. Test print quality before production.

Can I generate QR codes with this tool?

No, this tool generates linear (1D) barcodes only. For QR codes (2D barcodes), use a QR code generator. Linear barcodes store data in vertical lines, while QR codes store data in a square grid pattern. Use the appropriate tool based on your needs.

When to Use This Tool

Use this when:

You need to create barcodes for product labels, packaging, or inventory management
You're working on retail applications and need barcodes for products
You want to generate barcodes for shipping labels or logistics
You're creating barcodes for library systems, asset tracking, or identification
You need barcodes for event tickets, membership cards, or access control
You're developing applications that require barcode generation
You want to test barcode scanning systems and need sample barcodes

Don't use this if:

You need QR codes instead of linear barcodes (use QR code generator)
You require 2D barcodes like Data Matrix or PDF417 (use specialized 2D barcode tools)
You need barcodes with specific industry standards or certifications not supported
You want to scan or read existing barcodes (use barcode scanner apps)
You require barcodes for very large-scale production with specific printing requirements

What is a Barcode Generator?

A barcode generator creates scannable barcodes in various formats (Code 128, Code 39, EAN-13, UPC-A, ITF, and more) from text or numeric input. Our generator runs entirely in your browser — your data is never sent to any server.

Barcodes are ubiquitous in commerce and logistics: product identification in retail (UPC, EAN), inventory management in warehouses, asset tracking in organizations, shipping labels, library book management, and event ticketing. Being able to generate barcodes quickly without specialized software is valuable for many professionals.

This tool is ideal for small business owners creating product barcodes for retail, warehouse managers generating inventory tracking labels, event organizers creating ticket barcodes, librarians generating book identification codes, and developers testing barcode scanning functionality in applications.

Compared to paid barcode software (which often costs $50–200+), online generators that require accounts and add watermarks, or hardware-specific barcode printers with proprietary software, PureXio generates professional-quality barcodes for free with full customization.

The tool supports multiple barcode formats for different use cases: Code 128 (general purpose, alphanumeric), EAN-13 (European retail products), UPC-A (North American retail), Code 39 (industrial/government), ITF (shipping containers), and more. Output barcodes can be downloaded as PNG or SVG, with configurable width, height, and display options.

Best for: generating barcodes in Code 128, EAN-13, UPC-A, Code 39, and more. Customizable size, PNG/SVG output. No software needed. Fully private.

Limitations & Constraints

Supports linear barcodes only—doesn't generate 2D barcodes (QR codes, Data Matrix)

Barcode format must match content type (e.g., EAN13 requires 13 digits)

Very long text may not fit in all barcode formats—some formats have length limits

Barcode scanning accuracy depends on print quality and scanner capabilities

Some barcode formats have specific requirements (e.g., EAN13 requires valid check digit)

Troubleshooting

Barcode generation fails or shows error

Solution: Check that content matches barcode format requirements. EAN13 requires exactly 13 digits. UPC-A requires 12 digits. CODE128 supports alphanumeric content. Ensure content is valid for selected format. Some formats require specific content length or character types. Prevention: Verify content matches format requirements before generating.

Barcode doesn't scan correctly

Solution: Ensure barcode is printed at sufficient size and resolution. Barcodes need adequate width and height for scanning. Check that barcode format matches scanner capabilities. Some scanners only support specific formats. Verify barcode content is correct—errors in content cause scanning failures. Prevention: Test barcode with scanner before production use.

Barcode text is too long for format

Solution: Different barcode formats have different length limits. CODE128 supports longer text than EAN13 or UPC-A. If content is too long, use CODE128 format or shorten the content. EAN13 and UPC-A have fixed lengths (13 and 12 digits respectively). Prevention: Choose format that supports your content length.

Barcode image is too small or too large

Solution: Adjust width and height sliders to resize barcode. Larger barcodes are easier to scan but take more space. Smaller barcodes save space but may be harder to scan. Find balance between size and scannability. For printing, ensure resolution is sufficient (300 DPI recommended). Prevention: Test barcode size with your printer and scanner.

Need different barcode format

Solution: This tool supports common barcode formats (CODE128, EAN13, UPC-A). For other formats (Code39, ITF, etc.), use specialized barcode generators. Check format dropdown for available options. Most common formats are supported. Prevention: Verify required format is available before generating.
