Compare view and keyboard shortcuts

The preview has three modes (Compare, Result and Original) and six keyboard shortcuts, so you can check a cutout and save it without reaching for the mouse. On Windows and Linux use Ctrl wherever this page shows ⌘.

What are the three preview modes?

The switch at the top left of the preview picks one:

Mode	What you see	Good for
Compare	Original on the left of a divider, cutout on the right, labelled BEFORE and AFTER	Checking edges: drag the divider across hair, fur and fine detail
Result	The cutout on its own, over the background you chose	Judging the final look
Original	The photo as you added it	Seeing what the model had to work with

Every new photo opens in Compare. While a photo is still being processed you see the original, whatever the mode.

The background behind the cutout in the preview is drawn with CSS rather than baked into the image, which is why switching colours is instant even on a 40 megapixel photo. The real composite is only drawn when you download or copy. The blur preview is a close approximation; the downloaded blur is scaled to the output size (see Backgrounds).

How do I use the before and after divider?

Drag it with a mouse, a finger or a pen. Clicking anywhere on the photo jumps the divider to that point. With the keyboard, ← and → move it 5% at a time. Screen readers get the same control as a labelled slider ("Compare the original with the result").

The status line at the top right tells you how the cutout was made, for example GPU · 1.4s · 3024×4032. That is the model tier that ran, the time from start to finished PNG, and the output size in pixels. If it says CPU on a computer where you expected the GPU, Models and hardware lists the conditions for the GPU path.

What keyboard shortcuts are there?

Adding photos:

Keys	Action
⌘ O	Open the file picker
⌘ V	Paste an image from the clipboard

Checking and saving:

Keys	Action
Hold Space	Peek at the original; let go to return
← →	Move the compare divider by 5% (Compare mode only)
Esc	Show the next image, when there is more than one
⌘ C	Copy the finished cutout as a PNG

A few rules keep these from getting in your way. Shortcuts are ignored while you are typing in a field, such as the pixel size boxes. Space does nothing when a button or link has keyboard focus, so it still presses that button. And ⌘ C only copies the image when no text is selected on the page, so copying a sentence from these docs or the tool page still works as normal.

What does Copy put on the clipboard?

A PNG of the current cutout with your background, size and crop settings applied, whatever the chosen download format. The clipboard in browsers takes PNG images only. If your browser refuses image writes, the tool tells you so and the Download button is the fallback; Troubleshooting has the details.

Does the tool remember my settings?

Yes. Background choice, colour, size mode, scale, pixel sizes, crop, padding, upscale and format are saved in your browser's local storage and restored next time. A background image you picked is not kept, because it is a file and local storage only holds text; the setting falls back to None.
