CodeSquare

Create useful QR codes entirely offline, with a clear preview before you save or share.

Choose the format that matches your content:

• Text for messages, notes, and special characters
• Website for a basic web address check without opening or visiting the site
• Contact for a name, phone number, and email in a structured format
• Wi-Fi for a network name, password, and security type

Adjust error correction, quiet zone, and high-contrast color in the preview. The app uses standard square QR modules to keep codes easy for common scanners to read. Empty content and content that exceeds QR capacity cannot be generated or saved.

After reviewing a code, copy the original content, save a high-resolution PNG to the device, or keep the project in local history. Saved projects can be searched, opened again, and deleted with confirmation. Wi-Fi projects are treated as sensitive and require an explicit confirmation before their password is stored locally.

Everything happens on your device. There is no account, upload, cloud sync, advertising, payment, link access, camera, scanning feature, or safety judgment. A QR code is only a container for content, so take care when scanning unfamiliar codes and sharing sensitive information.
