Please recommend a simple QR Code generation app with the following features:

  • Portable (no installation)
  • Gratis (free of cost)
  • Windows compatible
  • Completely offline (does not attempt internet access)

Thanks!

  • what do you mean by "a simple [...] app"? - a stripped down GUI? light on resources? qr-generation only via plain text? – DJCrashdummy May 26 '18 at 10:51
  • @DJCrashdummy Something that simply generates a QR Code from a string. – RockPaperLizard May 26 '18 at 21:31

Download from Sourceforge, unzip file to a folder and create shortcut to qtzint.exe, double click shortcut to run. I hope this Helps!

  • Wow! That looks powerful. Thank you for your contribution. – RockPaperLizard Aug 17 '17 at 16:03

You can use WinPython + a couple of libraries to get what you need with the following steps:

  1. Download WinPython, (in this case I would recommend a 32 bit zero edition as that is a lot smaller and should work on any windows machine).
  2. Run the downloaded executable and select your USB drive as an install location, (you will need about 85 MB free with the zero edition).
  3. On your USB drive select and run WinPython Command Prompt.exe
  4. In the resulting command prompt run pip install Pillow qrcode colorama
  5. Wait a few seconds for the install to finish
  6. You can now disconnect from the internet
  7. Test with the command, in the same command prompt qr https://sourceforge.net/projects/winpython/ you should get the resulting QR on in the command window. Command Window Result
  8. You can output to a file in svg format with a --factory=svg flag: qr --factory=svg https://sourceforge.net/projects/winpython/ > link.svg
  9. You can also create in any PIL supported format, (most image formats), with qr --factory=pil https://sourceforge.net/projects/winpython/ > link.jpg enter image description here

All of the above is:

  • Free, Gratis & Open Source
  • Windows Compatible
  • Portable
  • Offline once installed.

Of course you now also have the power of python available.

i stumbled across a program you are probably interested in... Portable QR-Code Generator:

  • generates qr-codes from several data (simple text, URLs, eMails, vCard, WiFi, GPS)
  • is a portable app packed into just one jar-file (<1MB)
  • is gratis and also free as in speech (GPLv3)
  • is cross platform usable as long as JRE6 or newer is installed
  • why should it need internet access? - i haven't controlled it, but i doubt such a nasty behavior.

the only downside is, that its development seems to have stalled years ago... but well, it's open source and based on ZXing. so if there is an essential update really necessary, it shouldn't be that hard to accomplish.
