: How to remove white background from multiple images? So I received approximately 70 or so images from a customer and apparently they were all scanned. They are 4x6 prints but each one has a

I learned a quick tip about removing white background from an image a while back and I think it will apply here.

Here it is step by step.


Duplicate the background layer (Ctrl+J) and hide the background.
Go to the blending options by either double clicking on the layer or right click > Blending Options.
Under the Blending Options > Blend If > This Layer, drag the handle on the white side while pressing ALT key to remove the white background layer.

Just a quick and easy way to remove white background from any image. Look at the screenshot for reference.


Make an action out of this and you can batch process all of your images.

This is a job for the actions palette!

Make a new action for "Auto Crop"


Open Actions palette (Alt+F9)
Hit the "create new action" icon bottom right (paper with folded corner)
Name the action "Auto crop" (for example)
Go to Image > Trim > "Top left pixel color" (make sure all four boxes are ticked) > OK
Save as (Shift+Ctrl+S) (then indicate your output directory)
Close (Ctrl+W)
Stop the recording action


Use that new action on a batch


File > Automate > Batch
Set "Source" to "Folder" and browse to the folder with the originals
Set "Output" to your destination folder of choice (I recommend a new folder!)
OK


...sit back and watch the action :)

It's worth mentioning that if you don't actually want them cropped THAT tightly (to the pixel) you can always add to the action a step to simply increase the canvas size (say) 50 pixels all round after the trim. You can also at that point run Auto-Tone, or anything else you'd like to do.

Once you are into actions and batch automation, there is no going back!
