How to bulk resize images provided they are larger than given height and width values?

Question

Automation

Hello, let's say we have 1000 images that have different widths and heights. Of these images, only those whose width values ​​are larger than a certain value (for example, 800 px) need to be scaled down. Perhaps someone knows if there is already a ready-made solution?

Answer 1

All questions about batch image conversion have one answer - Imagemagick .
Specifically, in your case, it can help: convert -resize 600x600\> filename.jpg
This problem was discussed in more detail here .

Answer 2

I do this with Picasa. If you specify a size in the export, it will reduce those images that are needed so that both the width and height fit into this size. If the dimensions for width and height are different - I don't know.
