I have been using snappify.com for over a year now and I absolutely love it.
I've used snappify to create code snippets to share on social media[1], I've used it to create YouTube video thumbnails, and I've used it to create slides for talks that I've given at big international conferences[2].
I have no affiliation with snappify whatsoever, and I'd love to see your comments on this tool.
What things look good/promising?
What's missing?
What other alternatives could I consider for similar purposes?
