A barcode generator converts your data into a symbol that a compatible scanner can read. QR Code AI creates static barcodes for retail products, stock records, cartons, books and component labels. For example, enter SKU-1042 in Code 128 to create an internal inventory label: a scan returns SKU-1042, which your inventory software can match to its record.
Create a label that fits your workflow, check the rendered symbol and keep the saved artwork organised. These tools work across all ten barcode formats.
Set foreground and background colours to fit your label. Keep bars or modules darker than the background; the live preview warns when contrast is too low. For linear barcodes, show the human-readable value for manual entry or hide it for a simpler label. Data Matrix uses the symbol without a text caption.
Review the High, Medium, Low or Not scannable result before saving. Fix a Not scannable result to continue. Each download is checked against your saved data and format; unreadable or mismatched files are blocked. These checks do not certify print quality.
Download PNG, JPG or WebP images, or SVG, PDF or EPS vectors. Each file preserves the colours and proportions of your saved barcode.
Adjust extra padding from 0 to 32 pixels. The required quiet zone, the clear area around the symbol, remains even at zero extra padding. Preserve it when placing the download on packaging or a label.
Find saved Barcodes with search and tags, inspect their encoded value and format, or duplicate one as a starting point. Archive and restore items, and review up to one year of change history.
Keep barcodes, QR codes and Smart Links in one Workspace. Create and edit barcodes as a Workspace Owner or Member. Viewers can preview, download, export and read history. Filter by member or export up to 10,000 matching records as CSV. The CSV contains records, not barcode images.
QR Code AI also creates QR codes for website links, WiFi access and documents. Use a barcode to identify a product and a QR code to open its instructions. Share branded short links in emails or messages with Smart Links.
Integrate barcode generation into your applications and workflows. Use product numbers or inventory IDs from your own system to create barcodes for labels and packaging. Automate repeated creation tasks without entering each value manually in the editor.
Go from an identifier to a downloadable barcode in three steps.
Select the format required by your scanner or receiving system. Enter your identifier, or use the structured fields for GS1-128. The editor checks the input and provides check-digit guidance where applicable.
Adjust the foreground, background, human-readable text and padding. Review the automatic readability result as you make changes. If the result is Not scannable, correct the design before saving.
Save the Barcode, then choose PNG, JPG, WebP, SVG, PDF or EPS. The final download is checked against the saved data. Test a printed sample at its intended size, on the intended material, with the receiving system. Use formal barcode verification when your trading partner requires it.
Choose by the data you need to encode and the system that will read it. For retail and logistics, follow your trading partner’s requirements and the GS1 guide to choosing a barcode.
Letters, numbers and supported ASCII characters
SKU-1042
Uppercase letters, digits and selected punctuation
A 13-digit product number, including its check digit
An assigned 8-digit product number
EAN-8 requires its own assigned identifier; it is not a shortened EAN-13.
A 12-digit product number, including its check digit
An eligible compressed UPC number
UPC-E compression applies only to eligible UPC numbers.
A GTIN represented as 14 digits
Structured Application Identifier fields
Code 128 and GS1-128 serve different needs. Use the GS1-128 fields when the receiving system expects structured data such as a lot number or expiry date.
A valid ISBN-10 or ISBN-13
Supported text or identifiers
Use a compatible 2D scanner. This generator creates generic Data Matrix, not GS1 DataMatrix.
Open a dedicated generator for input rules, examples and format-specific guidance. The same editor supports every format and all six download options.

GS1-128 Barcode Generator
Create a book barcode from an existing ISBN-10 or ISBN-13. Check the normalised number, add an optional five-digit supplement and export the artwork.
ISBN Barcode Generator
Create a Data Matrix symbol for supported ASCII text or internal identifiers. Keep clear margins and export vector or raster artwork.
Data Matrix GeneratorChoose image files for everyday layouts or native vectors for scalable artwork.
PNG for labels and image layouts.
JPG for software that requires JPEG.
WebP for compatible digital layouts.
Images are at least 1024 pixels wide and keep the barcode’s proportions. Long barcodes may be wider so each bar stays at least three pixels wide. Data Matrix exports are 1024 × 1024 pixels.
SVG for design tools.
PDF for print layouts and documents.
EPS for packaging and illustration workflows.
All three preserve vector shapes, text outlines, colours and gradients. Keep the complete barcode and its quiet zones when resizing. Choose the physical print size for your barcode and scanner; pixels alone do not determine it.

Yes. Create three Barcodes in your personal account and three in each non-Premium Workspace, with free PNG, JPG, WebP, SVG, PDF and EPS downloads. Editing does not use a creation slot; archiving does not restore one. Premium allows more creations. Barcode creation, editing and downloads never start the seven-day trial. The encoded value keeps working after a trial ends.
You can choose a format, enter data, customise the design and check its readability in the website editor before signing in. Sign-in is required to save the Barcode to your account and download it. Your in-progress design stays on your device, and the same design continues into your account.
No. QR Code AI creates the barcode image from the number you provide; it does not issue a GTIN or ISBN or register a retail product. For an item sold through a retailer or marketplace, use the assigned identifier and the format that partner requires. For an internal inventory label, use an identifier linked to your own stock record. GS1 US explains the difference between a GTIN and its barcode.
A standard EAN or UPC product barcode carries an identifier. The checkout or inventory system uses that number to retrieve the product name, price and other details from its database. Generating the symbol does not create those records. The ISBN option can also include a five-digit price add-on when the book workflow requires it.
These barcodes contain their value directly and have no built-in expiry date or managed redirect. The printed data stays the same. A receiving system can still reject an unknown identifier, so keep the corresponding inventory or product record available. An expiry date encoded as a GS1-128 data field describes the item; it does not switch the barcode off.
You can edit the saved Barcode and download an updated image. Changing the encoded value requires replacing the existing printed or shared symbol; old copies keep their original data. QR Code AI Barcodes do not include scan analytics. Your inventory or checkout software may record scans within its own workflow.
A phone needs a camera app or scanner that supports the chosen barcode format. Support varies, and Data Matrix needs a compatible 2D reader. Test the final label with the actual device and software your team will use. The editor’s automatic readability check does not guarantee that every camera app supports the format.
Barcode is the broader family of machine-readable symbols. Linear formats such as Code 128, EAN and UPC use bars; QR codes and Data Matrix use two-dimensional patterns. This editor offers nine linear format options plus generic Data Matrix, not GS1 DataMatrix. For a website link, WiFi connection or hosted document, use the QR code generator.
