Getting to a first result
A browser workflow is suited to a quick initial assessment: open the linked experience, provide an image if its available controls allow it, and review what comes back. Photoshop starts with an editing workspace and asks you to choose and adjust a technique. That extra setup is useful when you already know which part of the photo needs attention.

Controlling the correction
Photoshop offers established editing tools for sharpening, local selections, masks, and layered revisions; the exact options depend on your version and workflow. A web-based result is better treated as a first-pass proposal unless the linked product explicitly offers comparable controls. If only a face or a sign is soft, selective editing may avoid sharpening distracting background texture.

Judging fine detail
Inspect text, eyelashes, hair, straight edges, and repeated patterns at the same zoom level. Enhancement can make a photo appear crisper while changing small features or creating edge halos. Photoshop also allows over-sharpening, so manual control is not a guarantee of accuracy. Keep the untouched original beside every version you evaluate.

Finishing the file
For a casual photo, one acceptable result may be enough. For a client image, archive scan, or print, compare the whole frame, check important details against the source, and retain an editable master if you need further revisions. The best-looking preview is not automatically the most faithful final file.
