BUILT FOR THE REAL WORLD
Everything your label needs.
Nothing it doesn't.
Structured GS1 encoding
Use supported (AI)value identifiers with check-digit and length validation, plus automatic FNC1 separators.
Labels at scale
Import CSV or TSV inventory, export an organized ZIP, or print sheets with readable captions.
HOW IT WORKS
From text to label
in three steps.
- 01Enter your identifier. Use any text, SKU, serial, or GS1 element string.
- 02Choose dimensions. Keep Auto sizing for the easiest fit; set a quiet zone and colors.
- 03Export or print. Save lossless SVG, crisp PNG, or a batch ZIP with a manifest.
GOOD TO KNOW
Printing & scanning tips
Quiet zone: keep a clear margin of at least one module on every side. Two or more is a useful practical default.
Physical sizing: select the correct module dimensions for your printer, material and scanner. A vector file avoids blur when scaling.
Verify the output: test-scan real printed samples using the intended equipment before production. This tool does not certify print quality or GS1 compliance for a given application.
International text: text outside Latin-1 is encoded as UTF-8 with ECI 26; confirm ECI support in your scanners.
FREQUENT QUESTIONS
Questions, answered.
What is the difference between Data Matrix and QR code?
Both are two-dimensional barcodes. Data Matrix ECC 200 is common for tiny parts, serialized goods, medical labels and direct-part marking; QR codes are common for consumer-facing links. Scanners and application rules determine which to use.
What does GS1 DataMatrix add?
GS1 DataMatrix uses structured Application Identifiers (AIs), a mandatory initial FNC1 and separators after variable-length elements when more AIs follow. Choose the GS1 mode for supported (AI)value input, not the plain-text mode.
Are files uploaded or stored?
No. Encoding, CSV parsing, image generation and exports run within your browser. Your data is not sent to PixelOkay. The current code and uploaded rows are held in page memory until you close or refresh the tab.
Can I export directly to PDF?
Use “Print labels / PDF” and choose your browser’s Save as PDF printer. It uses the browser print workflow rather than rasterizing a PDF inside the tool.
