Show HN: I built a free tool to make Before–After comparison videos

I often wanted to show photo restoration results in a clean before–after format, but most video tools were either paid or overly complicated.

So I built a simple web tool — you upload two photos (before and after), and it automatically generates a sliding or fade video showing the transformation.

It’s useful for photo restoration, AI art comparisons, makeup, design edits, and more.

You can try it for free here: https://beforeafter.online/
