QR Code Generator

QR Code is a two-dimensional barcode developed in Japan in 1994 by DENSO WAVE. This tool generates QR images locally in your browser for text, web links, email drafts, phone numbers, Wi-Fi settings and vCard 3.0 contacts.

Choose a content type and enter your details. For example, use https://example.com/events for an event page, or Hello, world! for plain text. The image updates automatically. Open Customize to change its size, colors, quiet zone and error correction level, then download a PNG or SVG.

PNG is useful for documents and everyday sharing. SVG keeps the modules sharp when scaled. Preserve the surrounding blank area and test the final image on the intended screen or printed material.

• Text and URL: plain text is stored as entered. URL mode accepts HTTP and HTTPS, and adds HTTPS to a host entered without a scheme. It does not check whether the destination exists or is trustworthy.
• Email: a recipient such as alex@example.com, an optional subject such as “Event enquiry”, and an optional message form a mailto link. A compatible email app can open a draft; scanning does not send it.
• Phone: use a country code when sharing internationally, for example +1 202-555-0142. The tool accepts 6–15 digits with an optional leading + and common separators. It does not verify that a number is assigned or reachable.
• Wi-Fi: enter the exact network name and password, then match the network's security type: WPA, WEP or None. For example, a fictional network might be called Example Guest. These choices describe connection data; they do not change the router's security. Enterprise authentication and hidden-network settings are not supported.
• Contact: enter a family name, a given name, or both, with optional phone, email and organization. For Alex Taylor, the English tool writes the display name as “Alex Taylor” while preserving separate family and given name fields in vCard 3.0.

The QR symbol format is shared internationally. What happens after scanning depends on the reader, operating system and installed apps. Contact import and Wi-Fi setup may require confirmation or may not be supported. Test non-ASCII text and the intended action on the devices your audience uses.

QR codes can link to survey pages or share contact details. This tool does not issue secure event tickets, verify identity or track whether a ticket has already been used; those tasks require a separate system.

Four error correction levels are available: L, M, Q and H. DENSO WAVE gives approximate codeword recovery figures of 7%, 15%, 25% and 30%, respectively. M is a practical starting point for everyday use.

These figures concern codewords, not the percentage of the picture that can be covered or removed. Damage to detection patterns, printing quality and the reader also matter. They are not a guarantee that a logo or a damaged QR code will scan.

More content or stronger error correction may require a denser symbol. Choose among 150, 200, 300, 400, 500 and 800 pixels. If the image is too small, the tool tells you the minimum required size. Keep a quiet zone of at least four modules and a dark foreground on a light background. The contrast check is a helpful guard, not a scanning guarantee.

The displayed character and UTF-8 byte counts refer to the formatted payload. They are not the number of encoded QR codewords: numeric, alphanumeric, Kanji and byte encoding can use different amounts of space. The input guard is 7,089 UTF-16 code units; actual capacity is usually lower and depends on the content and error correction level. Shorten the content if it does not fit.

Your payload is processed in the browser and is not uploaded for QR generation. The page can still make normal requests for assets, usage measurement or advertising. On a shared device, use Clear all when finished.

A QR code is an encoding, not encryption. Anyone with access to a Wi-Fi QR image can read its password. Share images containing credentials or personal details only with the intended recipients.

These are static QR codes: the encoded content cannot be edited after an image is distributed. A URL's destination page may change independently, but the URL inside the QR code remains the same.
