Generate Data Matrix symbols that scan.

Tiny 2D code for parts marking; rectangular or square. Configure Data Matrix below — Any text up to ~2000 characters. Rectangular by default; square optional. Every symbol is decoded again on your device before export.

Content

Tiny 2D code for parts marking; rectangular or square.

Any text up to ~2000 characters. Rectangular by default; square optional.

Advanced (error correction, shape, GS1)
Style (colors, frame, caption, export size)

Symbol contrast 100.0% (minimum 40%). The companion color adjusts automatically to hold the minimum; downloads additionally require the colored symbol to re-decode.

Outer frame

Frame and caption ship in the SVG download; PNG exports the bare symbol.

Specification

StandardsISO/IEC 16022 / DIN 66401
Character setAny text up to ~2000 characters. Rectangular by default; square optional.
LengthsAny short text — serials, part numbers, URLs
Check digitsError correction fixed by the symbology or QR-studio owned.
Quiet zoneSpecification quiet zone enforced in preview and export (2 modules minimum for matrix symbols).
GeometryMatrix Symbologies; engine selects the smallest fitting symbol unless pinned.
CapacityUp to ~2000 characters here; the engine enforces exact capacity.

Usage

Data Matrix marks small parts and documents with dense square symbols: etch or print it where Data Matrix-style readers expect machine-readable serials.

  • Data Matrix on electronic components for traceability
  • Data Matrix on ID cards and tickets for gate scanning
  • Data Matrix proofs exported as PNG at explicit module sizes

Pros

  • Data Matrix scans on modern phone and industrial imagers.
  • Every symbol is read back locally before preview or download.
  • SVG export stays sharp for print; PNG covers quick sharing.
  • Only the controls this symbology accepts are shown.

Cons

  • Data Matrix needs calm quiet zones — nearby text breaks detection.
  • Glare, blur and low contrast are the usual reasons a symbol will not read.
  • Screenshots prove scannability, not print quality grading.
  • Custom colors stay locked until contrast and tinted re-decode pass.

Form requirements

  • Enter Any short text — serials, part numbers, URLs.
  • Any text up to ~2000 characters. Rectangular by default; square optional.
  • Downloads stay locked until the local read-back reproduces the payload.

How it works

Three steps, all on your device.

The same engine that reads 2D codes writes them — every symbol is decoded again before you see it.

01

Check the spec

Capacity, error correction and shape controls for this symbology are listed above.

02

Tune and style

Only the controls this symbology accepts are shown; every symbol is read back to prove it scans.

03

Download and print

Take a resolution-independent SVG or a PNG at your chosen module size. Nothing is uploaded.

Questions

Data Matrix Generator & Specs, answered.

If you manage servers by hand, see the engineering services behind this tools series.

What can I encode in Data Matrix?

Any text up to ~2000 characters. Rectangular by default; square optional. Example input is prefilled when the page loads.

How does Data Matrix stay scannable?

Error correction fixed by the symbology or QR-studio owned. Keep the quiet zone calm, use black-on-white for print, and export SVG for anything that gets resized.

Is my data uploaded anywhere?

No. Encoding and verification run entirely in your browser — the page makes no network requests with your data, stores nothing, and wipes the field after ten idle minutes.
