Which barcode format should you choose?
Select a format based on the system that will scan or process the barcode, not only on its appearance.
EAN-13, EAN-8 and UPC-A
Numeric retail-style formats that require the correct number of digits and check-digit structure.
Code 39
Supports uppercase letters, numbers and a limited set of symbols in compatible systems.
ITF-14
A numeric format used where a 14-digit value is required by the receiving packaging or inventory workflow.
MSI
A numeric barcode option used by some inventory, warehouse and internal identification systems.
Pharmacode
A specialized numeric format. Confirm compatibility with the exact scanning system before relying on it.
This generator creates the barcode graphic from the value you enter. It does not assign, register or verify ownership of product numbers, inventory identifiers or other encoded data.

Barcode printing and scanning tips
A technically valid barcode can still fail when printed or displayed poorly.
Keep strong contrast
Use dark bars on a clean, light background and avoid decorative effects that reduce edge clarity.
Protect the quiet zone
Leave clear blank space around the barcode. Do not place text, borders or graphics too close to the bars.
Use SVG for scalable printing
SVG stays sharp when resized. PNG is convenient for digital use and common office documents.
Test the real output
Test the barcode using the intended scanner, material, lighting and final physical size.
Barcode generator FAQ
Important limitations and practical answers before using the output.
Is the barcode generator free?
Yes. You can generate supported barcode formats and download SVG or PNG files without creating an account.
Is the barcode value uploaded to QRmakerX?
Barcode rendering happens in your browser. QRmakerX does not receive the value entered into the generator. The page does load external fonts and the barcode library from third-party providers.
Can this tool create official retail product numbers?
The tool renders the number you supply. It does not assign, register or verify ownership of retail product identifiers.
Why is my EAN or UPC value rejected?
These formats require numeric values with specific lengths and check-digit rules. Confirm the original number before generating the barcode.
Should I download SVG or PNG?
Choose SVG for scalable print artwork. Choose PNG for websites, presentations, documents and other workflows that expect an image.
Can I use the generated barcode commercially?
You may use the generated image, but you remain responsible for the encoded value, numbering rights, legal requirements and acceptance by the system that will scan it.
