I have 100 JPEGs open in one Preview window. All are the same size in pixels. All are selected in the Sidebar. While Image Size and Export and other commands work on all these images as a batch, the Crop command only works on the frontmost image.
Is there a way to extend Preview's batch processing capabilities to cropping, perhaps using AppleScript?
I've also tried in Photos.app with no luck.
try the `sips` command.
this cannot be undone so i suggest working on a copy of your files if not using a vcs or updating timemachine.
you can batch process with a loop in terminal.
cd your/image/dir
for f in *.«filetype»; do sips -c «h» «w» --cropOffset «Y» «H» "$f"; done
where:
`«filetype»` is the file extension eg `png`, `jpeg`
`-c` is the short opt for `--cropToHeightWidth` and `«h»` is pixels height, `«w»` is pixels width
`«Y»` is pixels from top, `«H»` is pixels on the horizontal axis
note:
if you specify 0 for the crop offset then the crop will be centered
an example I had images 3200x1800px
crop to left: 389, top: 32, Width: 2146, Height: 1723
sips -c 1723 2146 --cropOffset 32 389

Preview is not the drug of choice for batch conversion, and its AppleScript support is essentially useless. One alternative that offers powerful image batch conversion is Graphic Converter.
There is a free demo and it is reasonably priced for its extensive image processing power. I own GC 12 and do not receive any benefits from its vendor for mentioning the product here. It is available for purchase in the Mac App Store or directly from the vendor site.
