Export in background Off does not seem to work as a workaround in 30.3, but chaning the anti-aliasing to Art Optimized seems to improve the result.

jagged edges on rotated images (png) when exporting to psd
Art Optimized (Supersampling) enabled

Can confirm that disabling the "Export in Background" Feature does indeed cause the exported artboards to have the Anti-alias settings applied. How strange is that.

According to Abhishek Rao in the pinned reply, turning off Preferences > File Handling > Export in Background solves the problem. And it does for me.

Please fix!

This is pretty important to fix and using save for web is so inefficient! Please fix!

Still a problem, see work around here https://community.adobe.com/t5/illustrator-discussions/export-for-screens-messing-up-images/m-p/15257815#M440111

I'm using version 29.3.1 and the problem still persists.

It looks like such a simple bug to fix.

And the worst part is that I cannot even downgrade to a version that this feature used to work because this bug has been present for so long that none of the previous versions available for download on the CC app are working.

Feb 11 2025... still an issue, how many votes are needed for this to be fixed?

Adobe Illustrator 28.7.1 (Win 64bit) - Export bug

The "Art Optimized (Supersampling)" setting within Export For Screens > Format Options is not working correctly for any of the JPEG settings.

In the output, placed hi-res raster images are ruined, as if the "Type Optimized" anti-aliasing setting were selected.

Export for screens PNG format honors anti-aliasing setting, as user would expect.
Save For Web (Legacy) JPG format honors anti-aliasing setting too.
But "for screens" JPG output is broken.

[EDIT] admins seem to have merged this with another report of the same bug, which is fine except that our example images are now jumbled together.

I'm working on a Mac with Sanoma 14.6.1 and updated to Illustrator version 28.7.1. Now I get the same thing. When I use 'export for screens' on artboards that contain place images, they all export as pixelated images. I did set the export settings to 'art optimised', but it's like Illustrator ignores that and keeps on using the 'text optimised' setting. Attached two samples. One where I used 'safe for web' which looks nice and one where I used 'export for screens'. You'll notice that especially in the red text a lot of pixelated edges appear. Which would be typical if I used 'text optimised', not 'art optimised'. So I suspect that changing the export for screens settings to art optimised does nothing and Illustrator keeps exporting as text optimised images. I have to use safe for web now, but this gets cumbersome as I often have multiple artboards to export.

@peter true, exporting at 4x and resizing is a cumbersome workaround, but the only really suitable until they fix this...

@sjacobs Yes, you are correct. Thanks.
@ carrie Exactly. I'm exporting dozens of assets at a time. Ha, over and over since you dont see the mistakes until you click export.

@KO

"- adds white borders due to anti-aliasing the artboard edges"

this happens when your dartboards x / y coordinates are not an exact/whole pixel number (ie. no decimals).

>I'm not suggesting that as a workaround but simply noting that if you use Export As or Legacy Save for Web, the images dont have this poor rendering.

While this is true, you can only do these one at a time and have to name the file at time of export. It's extremely inefficient when with Export For Screens you can do many artboards with custom names at the same time. I understand you weren't posting a work around, but I also wanted to point out to the Adobe team that this is impractical for anyone who works at any kind of scale, which is probably MOST of it's users.

>How does this not have more votes?

I can answer that.
Because every now and then the topic is merged with a bunch of other threads (sometimes not even the same issue).
Then a week or so later an "engineer" comes in and closes the thread. Often citing something completely irrelevant and not addressing the problem whatsoever.

Then 5 minutes later one of us reopen a new thread with the same problem and the counter is back to zero.

Also: The problem goes beyond raster graphics, it happens with vectors too - scaled rasters are just far more noticeably degraded.

How does this not have more votes? Well...

Most people come here to vote for one specific pan they discovered.
You, K-O, upvoted more than 50! But Ai UserVoice has over 7500 bugs reported. Some of these are duplicates, some are poorly posted, without proofs or details, some are actually resolved, but even 5000 makes it 100 times more.
I bet most of these are familiar to everyday Ai users (they are for me!) ...but people just don’t care or don’t have time to vote for OTHER problems other than their-only-one-they-came-here-for :(
32 votes, even though every voice is precious, is hardly enough to change the prioritization queue, it seems.

So vote, vote, vote, vote, vote. This is our only effective tool to raise the awareness of the team.

In 28.6
Slightly rotated an image
Export for Screens > JPEG 100 Art Optimized.
They are horribly jagged and the Art Optimized setting is ignored. Embedded as well as Linked.

How does this not have more votes? I'm not suggesting that as a workaround but simply noting that if you use Export As or Legacy Save for Web, the images dont have this poor rendering. Asset Export also properly renders the image. Why? I would love to know what the thought processes is / was. What are the challenges limiting this feature? I would love to have one reliable and versatile method for exporting images.

The whole module needs a reexamination based on a real day to day designer's workflow.

Asset Export and Export for Screen should function to the same level as photoshop's save for web. Its 2024. We need this for web ads, site builds and social posts.

In addition to the rotate render issue, other problems exist with the Export for screens feature:
- adds white borders due to anti-aliasing the artboard edges
- detailed setting are missing
- I wish we could export ANY supported file types like tiffs, gifs or psd all via this one feature.
- Text rendering is poor at small font sizes.
