In this short guide, you’ll learn how to crop the image of a webcam added to Streamlabs.
This will be a necessary step for instance, if you want to add a Green Screen on the Background of your webcam capture in Streamlabs because if you put the chroma key far enough (which is recommended) there will be parts of the frame that do not have a green background.
But it will also be good for making more room for your screen content, or simply for hiding something!

How to Crop a Webcam (or any source) in Streamlabs
Here’s what you’ll need to do in order to control how much of your room or recording studio your webcam is able to capture.
Step #1 – Select the camera source you want to crop
As you have seen previously, in Streamlabs is possible to add more than one webcam.
The crops you are going to learn how to make are independent.
You can crop one webcam one way, and crop another webcam another way.
That’s why the first step is select within the Sources list, which device is the one you want to modify.

Step #2 – Quickly crop the webcam “on the fly”
The easiest way of cropping your webcam on Streamlabs, is after you have selected it, drag and drop the tiny white boxes of each edge while keeping the ALT key pressed.

By doing this, instead of changing the size of the source, you’ll be cropping the edge from the one you’re moving your cursor.
Step #3 – Fine tuning webcam cropping
With the above method, you can make a vague adjustment of what you want to see on the screen.
Although Streamlabs offers quite useful (green) guides while doing the cropping, you may be too picky when it comes to, for example, cropping your webcam symmetrically.
If this is your case, you’ll want to use the accurate adjustment.
You can launch it by doing a double-click on the source/layer (webcam) you want to modify > Transform > Edit Transform.

This will open a new window with certain parameters that you can modify.
This is where, for example, the image is rotated.
But the values you are interested in are those of the “crop” fields.

By default (if you haven’t cropped the webcam using the previous method) all the values will be 0.
But you can change them by any value you want here, to crop that size for each side: left, right, top and/or bottom.
How to reset a webcam cropped by mistake
If by mistake you’ve cropped way too much, all you need to do is:
- Drag and drop each side with the ALT key pressed to the outermost part of the camera.
- Or make a precise adjustment and set all the crop values to zero.
The fastest method though is to right-click on the webcam on the source list, and select Transform > Reset transform, to restore the original size.

Can you crop a webcam layer with a circle shape?
As you have seen, cropping your webcam in Streamlabs is really easy.
But maybe you don’t want to just crop the edges, but have your webcam cropped as a circle or another geometric shape.
In that case, you’ll need to use a filter.
- Right-click on the webcam layer > Filters > Edit Filters.
- You’ll need to add the one called Image/Mask Blend.
- Upload an image file of a white circle (or another shape) over a solid background.
- Leave the other parameters as default.

As you can see, cropping the webcam in this way isn’t much more complicated, but the result is much more professional.
