No. Everything runs in your browser - your file never leaves your device. How this is verifiable
The DataMatrix code is a two-dimensional matrix code (ISO/IEC 16022) that packs a surprising number of characters into a tiny area. You find it on components, circuit boards, medicine packs and shipping labels - anywhere space is scarce but the code still has to stay reliably readable.
You simply enter your text or number, choose the module size and instantly get a real, freely scalable SVG. Built-in Reed-Solomon error correction keeps the code readable even when part of it is damaged or dirty.
Generation runs entirely locally in your browser - your data is not uploaded, not stored, and no foreign library is loaded from a CDN. If the input does not fit, the tool says so honestly instead of producing a wrong code.

Limitations: Generates DataMatrix codes (ISO/IEC 16022) as SVG. For linear barcodes use the barcode generator, for QR codes the QR code generator. Data capacity is high but limited; very long inputs can fail - the tool then says so honestly.
No. The DataMatrix code is generated entirely locally in the browser; your data never leaves the device and is not stored.
For marking small components, for circuit boards and electronics, in the pharmaceutical industry (for example GS1 DataMatrix on medicines) and on shipping and logistics labels.
Both are 2D codes. DataMatrix is usually more compact and made for very small areas and industrial marking; the QR code is more common in the consumer space. For QR use the QR code generator.
SVG is a true vector and stays crisp at any scale - ideal for labels and print. You can convert it to a raster in any graphics program if needed.
