Settings
Each setting says in a line what it does and why. Here they all are, page by page, with how each one comes.

General
- The pages. General, Drop panel, Viewer, File association, Manager, Converter, Editor and Keys.
- Cobalt Photo Pro. The days left of the trial, or your subscription: Subscribe, or Manage subscription in the Microsoft Store.
- Language. The language of Cobalt Photo's windows and menus: the same as Windows, or another.
- Theme. Light or dark windows; Same as Windows follows the app mode set in Windows and switches with it.
- Start with Windows. Cobalt Photo is ready after you sign in, so the drop panel and the viewer open at once. If Task Manager's Startup apps turned it off, it says so: turn it on there.
- Version, and the links to these docs and to the privacy page.
| Setting | What it does | As it comes |
|---|---|---|
| Language | The language of the windows and menus. | Same as Windows |
| Theme | Light or dark windows. | Same as Windows |
| Start with Windows | Ready after you sign in. | — |
| Recent on the taskbar | Right-click Cobalt Photo Viewer or Manager on the taskbar: the pictures and folders opened last, one click away. Off: the lists are cleared. | On |
| Ask before deleting | Before pictures or folders go to the Recycle Bin, Cobalt Photo asks. Off: Delete sends them at once; Don't ask again in the question turns it off too. | On |
Drop panel, Viewer, Manager
Their settings are told with what they change:

Drop panelThe key, the shelf at the edge, where it opens — settings.

ViewerDouble click, the wheel, small pictures, switching, the plate, hiding the controls — settings.

ManagerThe thumbnails' names, tags and pins, the cards of the details, the map, the cache — settings.
Converter
How pictures are written — by Convert, Save as, the drop panel's actions and File Explorer's menu.
- JPG quality. For every JPG Cobalt Photo writes, from 50 to 100.
- Converting many pictures. Several at once — two or three side by side, as many as free memory holds — or one at a time, lighter on a busy PC.
- Sharpen when made smaller. A light sharpening after a picture is made smaller.
- Smaller for mail. The long side of the drop panel's copy for mail.
| Setting | What it does | As it comes |
|---|---|---|
| JPG quality | For every JPG Cobalt Photo writes: the panel's actions, Convert, Save as. Higher keeps more detail, lower makes smaller files. | 85 |
| Converting many pictures | Several at once, or one at a time. | Several at once |
| Sharpen when made smaller | A picture made smaller — by Convert, the editor, the copy for mail — gets a light sharpening after it, as cameras do for screens: hair, leaves and textures stay crisp, with no halos. Pictures with see-through parts are left as they are. | On |
| Smaller for mail | The long side of the drop panel's copy for mail: 1280, 1600, 2048 or 2560 pixels. | 2048 |
Editor
| Setting | What it does | As it comes |
|---|---|---|
| Saving an edited picture | Ask each time; always Replace the original (kept as a backup for a week, Undo puts it back); or always save an edited copy Beside it. A camera's RAW file is never replaced: a JPEG copy goes beside it. | Ask |
| Develop RAW files | A RAW file opens in the editor developed from the sensor's data — the whole frame, more in bright skies and dark corners, white balance on the real light — and the viewer, zoomed in past a camera's smaller picture, shows the whole shot. A second or more each time. Off: the picture the camera put in the file. | On |
| 16-bit TIFF and PNG | A RAW file or a 16-bit picture saved as TIFF or PNG keeps all its 16 bits a channel: smooth skies and room for more work or for print, in a file two to four times as big. Text, drawings, stickers, a watermark or a frame make it 8 bits. Off: always 8 bits. | On |
File association
Which of the 41 picture types open in Cobalt Photo on a double click — each with its icon and the app it opens in now — and Windows asked to make them Cobalt Photo's, all at once or one by one: File association.
Keys
The last page lists every key Cobalt Photo answers to, by where it works — the same list as All keys.
