Frequently Asked Questions
Does someone need an internet connection to read a Text QR code?▼
No! Unlike website URL QR codes that require an active data connection to load a page, a Text QR code encodes the words directly into the black-and-white pixel pattern. When someone scans it with an iPhone or Android camera, the raw text displays immediately on their screen even in airplane mode.
How many words can I store in a single Text QR code?▼
Under the international QR code standard (ISO/IEC 18004), a Version 40 QR code can store up to 2,953 bytes (approximately 500 words of plain text). For maximum scanning speed on small smartphone lenses, keeping text under 150 words is recommended.
Are my secret notes or serial numbers uploaded to your servers?▼
Never. The conversion from text to QR code occurs 100% locally in your web browser. No text is transmitted across the internet, logged, or saved to a database.
Can I encode multilingual text with accents or non-Latin alphabets?▼
Yes. Our encoder uses standard UTF-8 character encoding, supporting Spanish accents, French cedillas, German umlauts, Japanese Kanji, Cyrillic, Chinese, and emojis.
What is the best error correction level for Text QR codes?▼
Level M (15% error correction) is ideal for text. It keeps the square matrix reasonably compact while providing strong resilience against scratches or printing imperfections.
