Batch edit using macro to resize photos for web

[LindaYVR]

I followed these instructions to batch edit my photos: https://affinity.help/photo/en-US.lproj/index.html?page=pages/Macros_Batch/batchjobs.html?title=Batch%20jobs as follows:

save as Jpeg width = 1500  length left blank, PPI at 75 using a sample image

The problem is, if the images in my batch are not exactly the same width as the sample to create the macro, my images are distorted. And vertical images become horizontal, or horizontal images become stretch out. I tried the same thing in Photoshop Cs6 using horizontal and vertical images but did not have this problem. Also, I can't find a save for web option that shows me what the image will look like when I reduce resolution size (as I can in Photoshop). Please advise. Thanks.

Using resize does indeed set the original values. You will need to use the Distort > Equations filter.

Try this macro:

Layer > Unlock
Layer > Rasterize
Filter > Distort > Equations    Enter the following in the x and y fields, then Apply
x=x*w/1500
y=y*w/1500
Document > Clip Canvas
Layer > Rasterize and Trim

Maybe I am missing something needed in your batch job but if all you want to do is set the width to 1500 px & scale the height proportionally, I don't think you need a macro for that. Just enter 1500 in the Width field & leave the Height field blank as you have done, & make sure the "Preserve Aspect Ratio" box is ticked, like this:

Does this not do what you want?

Thanks John. I tried what you suggested, but Rasterize is greyed out, and so is Distort > equations. Plus wouldn't this make my images square? They are rectangles. Also I still need to reduce the resolution.

R C-R I tried as you suggested without making a macro and it worked. Thanks! (Doing the same thing as a macro did not work)

I don't know why Rasterize and Distort are not available, but if @R C-R's solution works then go for it.

In my macro, both x and y have the same scaling factor, (w/1500) so the aspect ratio is preserved.
