About This Tool

This tool provides a server-side PHP workflow to encode text or binary payloads into QR codes. It validates inputs, selects a QR version and error correction level, and outputs a PNG image or a data URL suitable for web embedding. It follows ISO/IEC 18004 and UTF-8 to preserve Unicode data. By modularizing the encoding logic, developers can reuse the core algorithm in APIs, workers, or batch processes.
Core features include: input normalization, support for UTF-8 text, error correction level options (L, M, Q, H), version handling auto or fixed versions, margin control, and output formats. Optional advanced features include batch encoding, high-DPI outputs for print, and integration hooks to store images to storage or return data URLs.
Use cases span embedded QR codes in invoices, URL payloads for product tracking, tickets, and customer-facing discounts. The tool is designed for developers who need deterministic results, reproducible encodings, and minimal dependencies. Its unique value lies in the clear separation of validation, encoding, and output formatting, enabling easy testing and reuse across PHP projects.

Frequently Asked Questions

Find Quick Answers

What inputs are required?

At minimum, provide the data to encode as a string and choose whether to auto-select version or set a fixed version. Specify the error correction level and margin to influence size and resilience. UTF-8 is supported for Unicode.

What output formats are supported?

The encoder returns either a PNG image as bytes or a data URL suitable for embedding in HTML or emails. Additional file path output can be returned by exporting the generated image to storage.

How is Unicode handled?

Input strings are encoded as UTF-8 by default, preserving non-ASCII characters. The QR encoding process uses that UTF-8 representation to determine capacity and module arrangement.

What standards govern QR codes?

The implementation adheres to ISO/IEC 18004 for QR code specification, ensuring compatibility with standard scanners across versions, error correction levels, and module patterns.
