Text Qr Generator

Quick answer: Create QR codes for URLs, text, and Wi-Fi credentials with size and error-correction control. Open 文本二维码生成 — everything runs locally in your browser, and files never leave your device.

Steps

1. Enter the text or URL in the QR generator.
2. Adjust size, error-correction level, and margin.
3. Download as PNG or SVG.

Important notes

• Longer content means denser dots — for print, shorten URLs first or low-quality printers will struggle.
• Error-correction H survives logo overlays and scuffed surfaces at the cost of density.
• QR content is fixed forever — point at URLs you control.

Common questions

Add a logo? Yes, with level-H error correction — test-scan before printing.

Bulk generation? One at a time here; script CSV-driven batches for volume.

Pro tips

Print distance and quiet zone decide whether a QR scans in the real world. Rule of thumb: the printed code should be at least one-tenth of the scanning distance (a menu code scanned from 50 cm needs ~5 cm). Keep the quiet zone — the blank margin around the code — at least four modules wide; designers love trimming it, and scanners hate it. For event posters viewed at a distance, generate at high error correction, print large, and test with two different phones before the print run, not after.

Does a QR code expire? No — the code just encodes text. It stops working only if the destination URL dies, which is why you should point at URLs you control.
