    Provided all files are set up the same way (if not, batch save out as png first);
    Set up an action that performs a CTRL+Left Click on the layer,
    Then ALT+i
    Then P to crop flush.
    Then CTRL+SHIFT+ALT+S to save for web as a png.
    Test it on a control group, once confirmed as working, batch run this action on your folder.

    If you have glow effects and such, there may be empty space that seems useless, but it still contains a pixel somewhere at the outermost edge.

      I created an action for trimming images with transparent backgrounds but when I run Batch for multiple files, Photoshop asks me every single time anyway whether I want the trimming to be based  on transparent pixels or whatever color in the corners. How can I skip on this dialogue and sort of set it to transparency by default so I can leave the computer and just let it run?

      @kaig11620057 - Action panel screenshot please, relevant steps expanded.


      I mean the standard dialogue when you trim a picture:

      Although I recorded an action having my preferred default options ticked, Photoshop asks me for every single picture in a batch process...and that is not the point obviously.

      Do you know how to skip this dialogue?

      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?

      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.

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