Seconding ShareX. This is an extremely powerful tool, but only if you want it to be. I was using it as a basic lightweight snipping tool for over a year before diving deeper into it's macro, automatic uploading, screen recording, and screenshot organization tools. Among it's other features is built in QR and OCR tools. Cool stuff!
