About QR Data Formatter
Format text for optimal QR encoding — analyze encoding modes, estimate minimum QR version, and compare capacity across formats.
How It Works
Paste your text to see which QR encoding mode applies, the byte count, minimum QR version needed at each error correction level, and tips for optimizing the data to reduce code size.
Frequently Asked Questions
What encoding modes does QR support?
Four modes: Numeric (0-9, most efficient), Alphanumeric (0-9, A-Z, space, $%*+-./:), Byte (any UTF-8), and Kanji (Shift JIS double-byte characters).
How can I reduce QR code size?
Use uppercase letters (enables Alphanumeric mode — 45% more efficient than Byte mode), shorten URLs, remove unnecessary data, and use lower error correction if the environment is clean.
