When exporting this particular file, a bunch of mysterious canvas space is being added.

Hi Todd,

use crop tool with Delete Cropped Pixels selected to crop the image. You have an unmasked area or something visible on a layer somewhere outside the canvas area.

Hope this helps

Even if I did, it shouldn't be exporting more than the image's canvas size.

I tried your suggestion just now, and actually before I posted this, and it makes no difference.

Ok, I tried it again, and the export was the same. However, then I hid and re-showed the layers, and export was correct. It's definitely some kind of bug.

I was able to duplicate your problem earlier, but now this works like there never was a problem, no matter what I try. Weird.

This reply was created from a merged topic originally titled Photoshop: Export As is broken...and always has been.

Photoshop export is broken, and has been ever since it replaced "save for web".

A disturbingly majority of the time, when exporting an image, it will disregard canvas bounds. Sometimes this will mean including areas outside the canvas, if pixels exist outside and have not been cropped and deleted - which is not always convenientĀ  (say if you are wanting a large background image that you may wish to move to create other media, and not permanently crop).

Often these are only 1px wide, and aren't noticeable in thumbnails, so you think the file had exported correctly, and you check it, and in windows photo viewer it's framed on black so if your image has a white background, like 90% of product images, you can't see it, until it gets uploaded to the client website on a white background and there's suddenly a GLARING line on one edge or partly on one edge of a picture.Putting a white fill around the edge does not fix the issue - as it's adding pixels outside the canvas bounds. The only workaround is to increase the canvas bounds, add white, and then re-crop the image. This is unacceptable - the exporter should export the canvas area, and the canvas area alone.

When exporting to specific sizes, it will randomly fail to export to the requested size, demanding '599px' instead of '600px', for example. Save for web never had this issue, and still doesn't.

I suspect the two issues are related - and I suspect it may have something to do with the calculations not using long/floating point precision so that the calculations are flawed.

The exporter is broken, and has been since it was introduced.

Export as doesn't replace Save for Web. You can still use Save for Web.

Sorry, that's just an outright lie. Save for web is, in Adobe's own words, "Legacy". 'Export As' has always been touted as such since 2015 in this article here - http://blogs.adobe.com/crawlspace/2015/06/save-for-web-in-photoshop-cc-2015.html, and this help article here -https://helpx.adobe.com/photoshop/kb/save_for_web_Photoshop_CC_2015.html .

While you're right in that I can still use save for web, Adobe states that it was too old to maintain and that 'Export As' functionality was far better - and it's right, for the most part. It's a far better export tool with advanced algorithms that blow other imaging software out of the water - WHEN IT WORKS.
However, it doesn't always work - it's broken, and has been since it was rolled out. What I'm complaining about is that issues haven't been fixed. The extra pixel adding and forced size changes for whatever reason are far more than a minor annoyance. If any other piece of software performed like this there would be outrage and refunds.
