アステカコードジェネレーター

Generate Aztec Code 2D barcodes from any text, URL, or structured data. Aztec codes are used in boarding passes, transit tickets, and ID documents due to their compact size and high damage tolerance. Configure error correction level and module size, then download the barcode as a PNG.

使い方

Enter your text, URL, or data into the input field. Use the preset examples for boarding pass, ticket, or URL formats. Adjust error correction level (higher levels tolerate more damage) and module size for your output requirements. The Aztec code renders in real time — click ダウンロード to save as PNG.

特徴

Real-time rendering – code updates instantly as you type
Configurable error correction – adjustable level for different damage tolerance requirements
Adjustable module size – controls the physical size of the output
Built-in presets – boarding pass, transit ticket, and URL examples
PNG download – export the generated code as a high-quality image
クライアントサイドのみ – your data never leaves the browser

 よくある質問

What makes Aztec Code different from QR codes?

Aztec Code has a bulls-eye finder pattern in the centre rather than the three corner squares of QR codes. This makes Aztec codes more compact at small sizes and allows them to be read without a quiet zone (the white border required by QR codes). Aztec codes are preferred in constrained spaces like boarding passes and transit tickets, while QR codes are more universally supported by consumer devices.
Why are Aztec codes used on airline boarding passes?

Aztec codes are the IATA standard for boarding pass barcodes (BCBP — Bar Coded Boarding Pass) because they can encode the required passenger name, flight, and seat data in a compact format that prints reliably on thermal paper, survives folding and light damage due to high error correction, and can be read quickly under varied lighting conditions in busy airport environments.
How does error correction work in 2D barcodes?

2D barcodes like Aztec use Reed-Solomon error correction, which adds mathematically derived redundant data to the encoded payload. When a portion of the barcode is damaged or unreadable, the decoder uses the redundant data to reconstruct the missing symbols. Higher error correction levels add more redundancy, allowing more damage to be tolerated at the cost of a larger barcode for the same payload.
What data formats can Aztec codes encode?

Aztec codes can encode any binary data, including plain text, URLs, structured formats like BCBP (boarding passes), vCard contact information, calendar events (vCal), geographic coordinates, and arbitrary binary payloads. The maximum capacity is around 3,832 characters for text or 3,067 bytes of binary data, depending on the error correction level chosen.
