Barcode Generator

Welcome to the Barcode Generator! This tool allows you to create various types of barcodes with customizable options directly in your browser.

Key Features:

• Multiple Formats: Supports common barcode types including CODE128, CODE39, EAN-13, UPC, ITF-14, MSI, and Pharmacode.
• Customization: Adjust barcode width, height, colors (foreground and background), font, text visibility, and text position.
• Live Preview: See the barcode update instantly as you change options.
• Download Options: Download the generated barcode as a scalable vector graphic (SVG) or a raster image (PNG).
• Validation: Basic validation helps ensure the entered data is suitable for the selected barcode format.

Understanding Barcode Options:

• Barcode Content: The data you want to encode (text, numbers). Validity rules depend on the chosen format (e.g., EAN-13 requires 12 or 13 digits).
• Barcode Format: The symbology standard used (e.g., CODE128 is versatile, EAN/UPC are for retail).
• Width (px/bar): The width of the narrowest bar in pixels. Affects overall barcode width.
• Height (px): The total height of the barcode bars in pixels.
• Display Value: Whether to show the encoded data as text below or above the barcode.
• Font/Text Position: Customize the appearance of the displayed value (if shown).
• Colors: Set foreground (bar) and background colors. Ensure sufficient contrast for scannability (black on white is standard).

How to Use:

• Enter the data you wish to encode into the "Barcode Content" field.
• Select the desired "Barcode Format" from the dropdown.
• Adjust other options like width, height, colors, and text display as needed.
• Click the "Generate Barcode" button.
• If the data is valid for the format, a preview will appear.
• Use the "Download SVG" or "Download PNG" buttons to save the barcode.
• If there's an error (e.g., invalid data), a message will indicate the problem.
