How to work with imagemagick?

Question

PHP

I have an image that I want to modify imagemagick via php.

The question is, how should I specify parameters without knowing how they will change my image?

For example, we take Photoshop, there we change something and immediately see the result. How does this work in imagemagick? Blindly apply changes?

Is there some online tool where I can upload an image and apply the necessary parameters, and then copy them into my code?

who is stopping you from experimenting with one test file (group of files).
if the result suits - apply in your script
