How to crop batch multiple images?

[hello8989]

I have a bunch of images that I want to trim. How to crop/ trim batch multiple images?

Thank you!

Do they all need exactly the same amount of crop and same positioning of crop?

If so, create a 'canvas size' action.  Then go to File > Automate > Batch.  Select your images and apply your Canvas Size action.

If each image needs a unique input, I can't think of a way to batch that.

Thank you, but what is 'canvas size' action?

I just want to trim the 'blank page' around my images.

Photoshop has a facility to record a set of repetitive actions which you can run in the future.

Canvas Size is a means to change the canvas size (not to be confused with resampling the image).  So if you had a canvas of (say) 200px x 200px.  If you set canvas size to 180px x 180px, you would reduce the canvas size by 10px on each side. (crop).

What do you mean by 'blank page'?  Why have images got blank page?

Image > Trim, based off transparency, upper left or lower right pixel colour?
