Can't change image size when exporting in Save to Web

Hi, I am creating an instagram carousel in photoshop - i.e. a very long canvas. I created a new blank canvas with the custom dimensions of 1350 for height and 9720 for width (it will equal 9 slides that are 1080). I added multiple images and then split the canvas into 1080 sections. When I go to export Save for web legacy, it shows that the image size is 8192 W and 1138 H. That's odd. When I try to change it to 9720 and 1350, it gives me this error. So I went with it to see what the images would look like but that has reduced the quality of my image slides. I go back in and double check that my canvas size is still what I put it as and sure enough it still is 9720 + 1350. So shouldn't the image size in export match that? If so how can I change it?

You could use View>New Guide Layout to divide the image into 9 sections, use the Rectangular Marquee Tool to Layer>New>layer Via Copy each section and then select all 9 layers right click and use Export As which should save thiose 9 layers to separate trimmed files.

OK so I see what happens. If you do anything in that Save for web window it will see the resize and do it. But, if you Save for web and don't touch any settings just click save you are good to go

I'm having this issue as well, even though I've done lots of carousels like that and it always exported the correct size, but for this file it doesn't

There's a better way to do this than the correct answer above. Start the same with the New Guide Layout to create your sections, then use the Slice Tool to get to the Slices From Guides button and that will create your sliced sections for output via Save for Web. Easy peasy.

Weird... I just did one where the canvas is 20000x2000 and split them into 9 slices and output 2222x2000 files no prob

Mac or PC?

Why create another topic?

I have added a script in the other topic to automate the process of splitting the image into columns and rows.

So now we know SFW reduces your panorama to 8192, but exports the slices. Export > Save as Jpeg can't export slices.

So if no one answers this problem, start a new topic explaining the situation.

8192 pixels H or W is the limit for Legacy SFW, so it will reduce your canvas to that amount as seen in the bottom right of the SFW dialog. Try File > Export > Export As > and choose jpeg in the dialog menu. It will allow 9720 px.

(I have to double check things, but that way you have good information).

Oh That's interesting! So I tried that and yes it now shows 9720 + 1350 and the quality looks so much better - however, now it saves it as one long image instead of exporting 9 individual photos from the canvas. I don't know why "save for web" process knows to automatically split the images where I have spliced them, but the Export > Export As > jpeg option doesn't retain the splices. So now is there a workaround for that?

I've never tried to split an image before either in SFW or Export This video gave a clear idea if what you are doing and unfortunately SFW is recommended because it generates

images from the slices. So this is where I'm stuck.

Oh and to clarify - in the first screen shot the error shows that I was exporting it as a GIF. I just did it quickly to reproduce the error for the screenshot. But I was trying it as a JPEG and that's what I want is jpg format - multiple (9) images to come out from this.
