Hi Adobe Community, can i ask for some help and advice please with regards to updating files in bulk to do the following .... i need to:

grab files one by one from a specified folder

trim image

make shorter canvas dimension = to longer canvas measurement (ie. square canvas)

resize image to 800 x 800 (only if size > 800 x 800)

Export > Save for Web with Quality Low to a specified folder

Close the image tab

Then move onto next image

Actions and scripting

All of this should be possible with an action and batch command.

Are the source images on a transparent background for the trim command?

After trimming, duplicate the image and rotate 90 degrees and reveal all to get a square canvas, then delete the rotated layer.

Or alternatively to the rotated layer trick, just use fit image and then canvas size, as mentioned here:

Save for web doesn't play nice with batch actions, you would need to use save as.

Otherwise a script would be required for save for web to use a variable file name.

Can you post a screenshot of the layers panel for one of the images? Are all files consistent in their layer structure?

File > Automate > Fit Image to 800 x 800 pixels has a checkbox option to resize images to the longest edge without enlarging.

Then resize the canvas to 800 x 800 pixels.

No need for the rotated layer trick (which is for transparent backgrounds).

The Batch command has an option to override recorded Save command paths and names. This doesn't work with Export > Save for Web. If running a Batch with a recorded Export command it will overwrite each file in the batch with the same name.... At least that's how I remember it working.

EDIT: I just tested, perhaps I remembered it wrong then...

Save for Web in an action will export with the existing filename. I use this daily.

that's a great trick to get the square canvas thank you. will give it a go, i'm fine doing actions but no idea with script writing. Yes all files are generally jpegs so should be fine. I'm still not sure with the resizing though.... our optimum size for the website is 800x800... so only want to resize the image if it is larger than 800 x800. If it is already smaller than i don't want to resize as will make bigger and distort the quality. I know what you mean with save 4 web being problematic so will use save as because with the rotation it may cause issues if the layer structure is then changed. Thank you so much for your reply.

So the trim command would then need to be based on the top left and or bottom right pixel colour as JPEG doesn't support transparency.

Due to the lossy nature of JPEG compression a pure white background may not remain that way, so when you re-open the JPEG file the trim command may or may not work as expected.

Can you provide some of the JPEG files for testing?
