Can it fix torn corners or missing pieces?

No. A tap or a stroke fills a small area from the picture beside it. A torn corner or a missing piece has nothing beside it to copy from, and rebuilding it would be inventing a picture. Crop it off in Finish instead.

Can it colourise a black-and-white photo?

No. Colour can be warmed or cooled and saturation changed, but nothing here adds colour that was never in the photograph.

What scan settings should I use?

Scan at 600 dpi or more for a small print, save as PNG or a high-quality JPG, and clean the scanner glass first — dust on the glass becomes specks on every scan, in the same place each time.

Every fix is made on this device.

Touch up an old photo

A recipe for a scanned print: specks and scratches, Auto for the fading, a straighten, a crop.

Drop a photo in. Tap the spot you want gone.Click to browse. A copied picture pastes straight in. Nothing is sent.Spot · Heal stroke · Edge dab · Lift · Red-eye · Level — 6 marks, then it stops

Nothing to hand?

A drawing, not a photograph. Drag the seam: a speck of sensor dust in the sky, something dark pressed against the top border, the lower left corner sitting in shade — one tap each, and the one at the border only shows with the seam pushed right.

What is wrong with it?

Optional — the uploader works without it. It takes about five seconds and can save you a tap you would have undone.

The order for a scanned print

Fix: tap each speck with Spot; drag a Heal stroke (key 2) along a short scratch.
Light: press Auto. A faded print usually gains contrast and loses a colour cast.
Fix → Level, or Finish → Straighten, if the print sat crooked on the glass.
Finish: crop off the scanner bed and any torn edge, then save.

Six placed fixes per photo is the ceiling. A print with dozens of marks is past a quick pass. Related: Remove spots from a photo, Remove a mark from a photo, Straighten a photo.

This is a touch-up of a scan — not reconstruction of torn pieces and not colourisation.
