Create QR codes locally from plain text, links, contact details, and Wi-Fi data.

Choose a content type, enter the required fields, and preview the QR code before saving. Adjust error correction, margin, color palette, and export size to fit different scanning needs. The app shows character counts and a simple complexity estimate while you type, and it prevents empty or invalid input from being encoded.

Saved projects can be renamed, searched, restored from trash, and exported as clear PNG images. Recent generated items remain available on the home screen for quick access. Wi-Fi projects are treated as sensitive content, and the app lets you decide whether to keep them locally.

Everything works offline. No camera, account, cloud sync, or network access is required.
