How can I reduce the width of white separator strips in a 2x2 photo collage?

I have a single image made from a 2x2 grid of four photos. In the middle there is one vertical and one horizontal white separator strip, each 30 pixels wide. I want to reduce those separators to 10 pixels wide by removing 20 pixels from the internal white strips and moving the surrounding image areas together. Is there software that can do this, or a simple editing method?

This can be done manually, and easily with any version of Photoshop.
Simply use the marquee tool (M) to select an image row or column, then the move tool (V) to adjust the position of that row or column to reduce the width/height of the white area.
After that process you can either use the trim function (edit > trim) to remove any excess canvas, or again use the marquee tool to select the area you would like to keep, then crop (edit > crop) to remove the unwanted edges.
If this is something you need to do more than once, a batch process action could be set up easily using the above steps

Yes. This is easy to do in Adobe Photoshop, and similar editors should also handle it.
A simple manual method in Photoshop is:
- Use the Marquee tool to select one side of the image split by the white strip.
- Use the Move tool to shift that row or column inward until the white gap is reduced from 30 px to 10 px.
- Repeat for the horizontal or vertical strip as needed.
- Remove any extra canvas at the edge with Trim or Crop.
If you need to do this repeatedly, you can record the steps as a Photoshop action and run it as a batch process.
So the basic approach is not really a special “strip removal” program, but selecting part of the image, moving it, and then cropping the excess.
