Compact Aztec profile for very small symbols (1–4 compact layers). Configure Compact Aztec below — Generate-only profile through pinned BWIPP; capacity is enforced by the encoder. Every symbol is decoded again on your device before export.

Runs locally in your browser. Nothing is uploaded; the field clears after ten idle minutes.
This symbology has no tunable options — the engine picks the densest valid symbol.
Compact Aztec stays black on white until this output path has an independent color/raster qualification.
Frame and caption ship in the SVG download; PNG exports the bare symbol.
| Standards | ISO/IEC 24778 |
|---|---|
| Character set | Generate-only profile through pinned BWIPP; capacity is enforced by the encoder. |
| Lengths | Short text for a compact Aztec symbol |
| Check digits | Error correction fixed by the symbology or QR-studio owned. |
| Quiet zone | Specification quiet zone enforced in preview and export (2 modules minimum for matrix symbols). |
| Geometry | Matrix Symbologies; engine selects the smallest fitting symbol unless pinned. |
| Capacity | Up to ~120 characters here; the engine enforces exact capacity. |
Compact Aztec marks small parts and documents with dense square symbols: etch or print it where Data Matrix-style readers expect machine-readable serials.

How it works
The same engine that reads 2D codes writes them — every symbol is decoded again before you see it.
Capacity, error correction and shape controls for this symbology are listed above.
Only the controls this symbology accepts are shown; every symbol is read back to prove it scans.
Take a resolution-independent SVG or a PNG at your chosen module size. Nothing is uploaded.

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.
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.
