QR codes that never leave your browser.

What you get

• Private by construction

  The QR code is computed in your browser. The page sends a strict Content Security Policy that forbids any network request, so it could not upload what you type even by mistake.

• Instant

  The code updates on every keystroke. There is no generate button and no waiting.

• PNG and SVG

  Download a 500 px or 1000 px PNG, or a vector SVG that stays sharp at any size, for print or signage.

• Made to be scanned

  Choose the error correction level, the margin and the colors. LadyQR warns you about low contrast and inverted colors, the two most common reasons a code fails to scan.

• Small and dependency-free

  It has its own QR encoder, with no libraries and no build step. PHP only generates the page, so it runs on the cheapest shared hosting.

• Accessible and translatable

  High-contrast borders, full keyboard use, light and dark themes. Translations work like WordPress, with standard .po files. English and Spanish are included.

Don't take our word for it

Privacy claims are cheap, so LadyQR makes them easy to check.

1. Open the live editor and your browser's developer tools, on the Network tab.
2. Type anything. No request is made: the page can only load its own files.
3. Look at the page's policy. connect-src 'none' tells the browser to refuse any connection, whatever the code tries to do:

default-src 'none'; script-src 'self'; style-src 'self'; img-src 'self';
connect-src 'none'; base-uri 'none'; form-action 'none'

The encoder is about 400 lines in assets/js/qr.js, and the only thing the page remembers is your settings, in your own browser. What you type is never stored.

Run your own

LadyQR is a handful of files. It needs a web server that can run PHP (Apache is the target) and nothing else, not even a database.

1. Download the repository or clone it.
2. Upload it to the root of your site.
3. Optionally, copy ladyqr-config.sample.php to ladyqr-config.php and set the interface language.

The README has the details, and DESIGN.md explains how it looks and why.

Where it is going

• Done: the QR code generator, with PNG and SVG, settings, warnings, dark mode and translations.
• Next: test it on a real 100 MB shared hosting plan, then add a private, single-user URL shortener that writes its redirects into .htaccess so Apache serves them without running PHP.
• Later: installation guide and a release you can upload by FTP.

The full plan is in docs/PLAN.md.
