Whitening can be a single move. Add a new layer, use a channel to select the bright skin areas, fill it with white — done. Then dial the opacity back so the skin texture comes through again. Three steps, about a minute to learn.
Before you start
- Open the Online PS (zaixianps.cc) site.
- Click File → Open at the top left of the page (or simply drag your image in) to load the photo you want to whiten.
The one-pass whitening steps
-
Create a new blank layer
At the bottom of the Layers panel on the right, click the “New Layer” button (the icon that looks like a sheet of paper) to create a blank layer, and make sure it sits above the original image.
-
Open the Channels panel and load the RGB channel as a selection
In the Channels panel on the right, hold Ctrl (Windows) / ⌘ Command (Mac) and click the RGB channel. Photoshop builds a selection from the brightness of the image — a luminosity-based selection.
-
Fill the blank layer with white and deselect
Switch back to the blank layer you just created and make sure it is still the active layer. Then:
- Press D to reset the foreground color to the default black, then X to swap foreground and background so the foreground becomes white.
- Press Alt+Delete (Windows) or Option+Delete (Mac) to fill the selection with white.
- Finally press Ctrl+D (Windows) / ⌘ D (Mac) to deselect.
The whole image brightens instantly — that is the “one-second whitening” effect.
Optional follow-up (use as needed)
- If the result looks too bright overall, lower the opacity of the blank layer in the Layers panel to somewhere between 70% and 90%.
- To keep more detail, set the layer mode to “Soft Light” or “Overlay” before filling with white — that also gives a more natural brightening.
- When you are happy, save the result to your computer with File → Export As → PNG/JPEG.
