CodeSquare

Create useful QR codes without an account, network connection, camera, or cloud service.

Encode the content you already have:

• Plain text for notes, messages, and special characters
• Websites with basic http and https format validation
• Contact details with optional name, phone, and email fields
• Wi-Fi network details with selectable security types

Review a real QR code preview before sharing. Adjust error correction, quiet-zone margin, and a small set of high-contrast foreground colors designed to keep the code easy to scan. Invalid or empty input is rejected, and content that is too long is clearly identified instead of producing a misleading image.

After generating a code, copy the original content, export a crisp PNG to local device storage, or save a project for later. Saved projects can be searched, opened for editing, renamed through a new save, and deleted from local history. Wi-Fi content is treated as sensitive and is never saved unless you explicitly confirm the save action.

The usage guide explains structured formats, scan reliability, and why unfamiliar QR content should be treated carefully. A local privacy statement explains that encoding and saved projects stay on your device. Core features work fully offline, with no accounts, advertising, payments, cloud sync, link opening, or QR scanning.
