Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on browser-based, no install needed, and helps adapt images to new aspect ratios caught me off guard. Limited control over generated content is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: browser-based, no install needed and helps adapt images to new aspect ratios. Where it lags: requires internet connection. On balance the feature set — especially adjustable extension on each side — justifies the 4 stars for our use case.
