Show HN: HDRify – easily make HDR emojis and memes

https://hdrify.com
2•tloten•3h ago
Reading the 'HDR-Infused Emoji' post on HN a few days ago (https://news.ycombinator.com/item?id=43717606) I couldn't help but think that such a chaotic-evil tool needs to be as easy-to-use as possible.

So, I made HDRify.com to help the less-technically inclined access the magic of HDR emojis & brighten their Slack channels :)

Note - only works on HDR screens with a browser that supports HDR - Chrome is relatively a safe bet.
