Qarto: QR Code Generator

Qarto makes QR codes. Type what you want encoded, watch the code build as you type, then save it as a PNG or share it.

Everything runs offline on your device. There is no account, no sign-up, no ads, and the app requests zero Android permissions — including no camera, because Qarto does not scan.

WHAT YOU GET

• Eight content types
A link, plain text, Wi-Fi credentials, a contact card, an email, an SMS, a phone number or a location — each with its own form and the right encoding.

• A live preview with the numbers
The version, the module count, the error-correction level and the mask are all on screen, along with how much of the capacity you have used.

• Error correction you can see
L, M, Q and H shown side by side with the same content, so the size you pay for the damage tolerance is obvious rather than theoretical.

• Design that stays scannable
Change the module and background colours, the module shape and the quiet zone — and get warned before you export if the contrast or the margin would break a scanner.

• Export at any size
512, 1024 or 2048 pixels, or as a vector. Saving goes through the system picker, so no storage permission is needed.

• A saved library
Every code you keep, with what it encodes, when you made it and how often you have exported it.

• No upload, no shortener
Your link goes into the code exactly as you typed it. Nothing is sent anywhere and nothing sits in the middle of it.

• Eight background themes
A full Appearance section with eight crafted backgrounds and a modern, animated navigation bar.

PRIVACY FIRST
Qarto has no camera feature, so it never asks for the camera. Everything you create stays in local storage on your device. Zero permissions requested.

Note on Wi-Fi codes: the Wi-Fi QR format stores the password in plain text. Anyone who scans the code can join the network. Qarto tells you this before you make one.

WHO IT IS FOR
Cafés and shops printing a menu or a guest network, anyone sharing a contact card at an event, and anyone who wants a QR code without an account or a tracking redirect.
