unable to export at this resolution. please lower the resolution and try again

after lowering the resoltion getting error again file unsupported

These are Photoshop instructions.

I'm also having the same issue. The artboard is 3.25x2.25 so I highly doubt exporting to a 300 DPI JPEG should cause an error.  Also, when I import the file in PhotoShop it shows up at 1/10th the original size.  If I change the size correct size before opening it works.  I confirmed the original file in AI was 300DPI and the size stated above.  Wouldn't it be great if someone from Adobe could solve this issue.

If you have a document of a set pixel dimension, you DO NOT export as 300ppi, you export at 72ppi. This gives you a 1-to-1 pixel export. I know it's kinda of confusing.

This will give you a 3600x3600 image as you desire. The resolution is irrelevant in this case... it's the number of pixels that's important. However, if you must, you can open the resulting file in Photoshop and set the Image Size Resolution to 300. All this does is add a flag in the header of the file, but does not change the actual amount of pixels in the image, but can affect how the image places in other documents like InDesign. i.e. a 3600 wide pixel image will place when dropped onto a page at exactly 12" wide.

I'm also having this same issue - none of the solutons have worked so far

I just found this thread, so this is mainly for anyone having this issue moving forward. Make sure anti-aliasing is set to none. I had changed two settings when exporting a different .jpg and I think that was causing issues. Attached photo has the settings that resulted in a successful export.

hi, don't worry, just save it in 36 ppi while exporting, it will save as jpeg and you won't lose any pixels as well.

thanks.

First u save that file in PDF format then you reopen that pdf in illustrator and save in png format.

My fix was to Load the Ai file into photoshop. Had to tweek the size once it was loaded but got the smoother image i wanted.

If you're exporting multiple artboards to jpegs, pngs, svg's, etc., when you go to save you need to make sure you have "use artboards" checked and then click all or the range you'd like to export. Otherwise, when "use artboards" isn't checked it thinks you're asking to export the entire workspace and all artboards into one single jpeg.
