What this is actually doing.
This runs a focused automated pass in the browser so you can inspect the result instead of handing the whole job to a larger app.
Smart / Local Tools
Pick the strongest photo from a batch.
Compare similar frames by focus, exposure and useful resolution, then choose the one that actually works best for your shot.
How the score works: Balanced favours focus first, then exposure and resolution. Choose Sharpness for action/product shots, or Exposure when several frames differ mainly in lighting.
Private by design: every comparison happens locally.
Useful to know
Four things worth knowing.
Where it stops.
It solves the named job, not every problem around it.
What to inspect.
Automatic results still need a human check around edges, text, faces and small details.
Worth knowing.
Keep the original until the finished result has worked in the place you made it for.
