Barcode Generator
Generate barcodes in various formats including CODE128, CODE39, EAN13, UPC, and more
Different formats have different requirements

Enter your data in the input field. The type and format of data depends on the barcode format you select. For example, CODE128 accepts any ASCII characters, while EAN13 requires exactly 12-13 digits. Ensure your data matches the format requirements for successful barcode generation.
Select your desired barcode format from the dropdown menu. CODE128 is the most versatile and commonly used for general purposes. EAN13 and UPC are standard for retail products. Choose the format that matches your industry standards and scanning equipment requirements.
Adjust the bar width using the slider to control the thickness of individual bars in the barcode. Wider bars (3-5px) create larger, easier-to-scan barcodes suitable for warehouse environments, while narrower bars (1-2px) are ideal for small labels and products with limited space.
Set the barcode height using the slider to match your label size and scanning requirements. Taller barcodes (150-200px) are easier to scan from various angles and distances, while shorter barcodes (50-100px) work well for compact labels and space-constrained applications.
Toggle the 'Show Text Below Barcode' option to include or exclude the human-readable text below the barcode. Including text helps with manual verification and troubleshooting, while excluding it creates a cleaner appearance for design-focused applications.
Click the 'Generate Barcode' button to create your custom barcode. The tool processes your input data and generates a high-quality barcode image that appears instantly in the preview area, ready for immediate use, printing, or digital integration.
Download your barcode in PNG format for printing on labels, packaging, and documents, or SVG format for scalable graphics in design applications. You can also copy the barcode to clipboard for quick pasting into documents, presentations, or image editing software.
Test your generated barcode with a barcode scanner before mass production to ensure compatibility with your scanning equipment and verify that the encoded data is correctly read by your systems.
Pro Tips
- Test barcodes with your actual scanning equipment before printing large quantities, as different scanners may have varying capabilities and format support. This prevents costly reprints and ensures reliable scanning in production environments.
- Choose CODE128 for general-purpose applications as it offers the best balance of data capacity, size efficiency, and universal scanner compatibility. It's suitable for most non-retail applications including shipping, inventory, and document tracking.
- For retail products, use EAN13 (international) or UPC (North America) formats as these are industry standards recognized by point-of-sale systems worldwide. Ensure you have valid product codes assigned by GS1 or appropriate authorities.
- Maintain adequate quiet zones (blank space) around barcodes when printing - at least 10 times the width of the narrowest bar on each side. This ensures reliable scanning by providing clear boundaries for scanner recognition.
- Use higher bar width and height settings for barcodes that will be scanned from a distance, in poor lighting, or with handheld scanners. Warehouse and logistics applications typically require larger barcodes than retail shelf labels.
- When printing barcodes, ensure high contrast between bars and background - black bars on white background provide optimal scanning reliability. Avoid colored backgrounds or low-contrast combinations that may interfere with scanner reading.
- Keep encoded data concise when possible to create simpler barcodes that are faster to scan and more resistant to printing imperfections. Shorter barcodes also occupy less space on labels and packaging, providing design flexibility.
