Troubleshooting

Barcode Generation Failed

Problem: Error message appears when generating barcode Solutions: - Verify your input contains only alphanumeric characters - Check that EAN-13 and UPC codes have the correct number of digits (13 and 12 respectively) - Ensure your input length doesn't exceed 100 characters - For QR codes, special characters and URLs are allowed

Bulk Upload Not Working

Problem: CSV file rejected or processing fails Solutions: - Ensure your CSV has the correct headers: main_input, barcode_type, output_format - Check that barcode_type values are valid (code128, ean13, upc, qrcode, pdf417) - Verify output_format is one of: png, svg, pdf - Make sure you haven't exceeded your tier's row limit - Confirm your subscription tier includes bulk processing (Pro feature)

Low Image Quality

Problem: Downloaded barcode appears blurry or pixelated Solutions: - Upgrade to Pro to access higher DPI settings (up to 600 DPI) - Use SVG format for infinite scalability - Use PDF format for print applications - Avoid resizing PNG images after download

Daily Limit Reached

Problem: Cannot generate more barcodes Solutions: - Wait until the next day for limit reset (resets at midnight UTC) - Upgrade your subscription tier for higher daily limits - Sign in to your account for increased limits vs. guest usage

Tips for Best Results

1. For Printing: Use SVG or PDF format with high DPI (300+ for Pro users)
2. For Web: PNG format at 150 DPI provides good balance of quality and file size
3. For Retail: Use EAN-13 or UPC-A for standard retail scanning systems
4. For Inventory: Code 128 offers excellent flexibility for alphanumeric SKUs
5. For Marketing: QR Codes are ideal for directing customers to websites or product info
