P: Export As does not support Actions or scripting

Allow "Export as" to be added to an action for quickly processing and exporting as file types other than jpeg or psd. 

Using poorly written scripts or plugins to solve for this is troublesome. It makes no sense to not be able to batch process in other file formats.

Any change you know what RD stands for?

Remember when Save for Web became a Legacy tool? That was in... 2015? Seems a pretty basic feature to be trying to figure it out for 7 years. After Effects can do all of these things. Another work around? Flatten your Photoshop files (annoying, but you can automate that - you need to do this because not all FX exchange between the two programs), bring all your PSDs into After Effects, create a comp for every photoshop file (one click), use RD comp setter to change the duration to 1 frame (one click after options set), change your default export settings to whatever image type you want (no vectors though, sorry), change your export path, select all your comps, add to render queue, hit go and watch your renders go faster than Bridge's Image Processor or "Export To" to "Export As" or Dr. Brown's OG Image Processor Pro. And again, Quick Export can do this to some degree, too. You just need to manually export each image. There are a lot of ways to achieve a more professional jack knife for exporting and it's pretty wild how far off Photoshop is right now... 

When I started using Dr. Brown's stuff in the OOs (late 90s maybe!?), I always assumed that Adobe would eventually integrate the very obviously missing tool. Now Photoshop does a killer job exporting lighter weight PNG w/ alpha. Dr. Brown's IPP was last updated almost 10 years ago. It still works, but it's not as good with its compression (or efficiency). But it'll save you time elsewhere if you don't need to tweak compression, etc. Ditto for Save For Web (Legacy). I haven't tested how AE compares with their stock settings, but I imagine it's closer to Photoshop then it is to Dr. Brown. 

Also, the community for scripting and plug-ins in After Effects for utilitarian purposes is leagues ahead of Photoshop. You'd be able to do your resizes in a jiffy @Stephen Marsh

Point being: really wild this isn't a thing. Maybe the most active (and aged) thread I've seen complaining about a piece of Adobe software that is broken.

Wait. You can't record "Export As" as a custom action? Why not? How is this still a problem 6 years later...

 

You also can't batch "Quick Export" 

 

There's a section on the left hand side of "Export As" that implies you could do multiple images simultaenously. But no such luck.

Adobe know that users wish to record Export As into an action or use it via scripting. It's a work in progress. 😐

You need to select multiple layers to Export As with multiple images. For a single layer image with 3 different sizes, you would need to dupe the layer twice, select all 3 layers and right-click Export As in the layers panel (not from the File menu, it's contextually dependent). Illustrated in this topic:

Oh you can still use "Save For Web" but it's incredibly slow...

You can also set your quick export option, assign a hotkey, and go through things pretty quickly.

I am having two problems:

1.  I wanted to wite an Action using Export As.  It is not being recorded in the Action.. The Action is:

a.  Flatten Image

b.  Fit Image 

c. Export As 

d.  Close without saving.

As shown in the screenshot below, the last Action in the list (selected) shows the "Export As" step I recorded does not show up, and the file is not saved in the destination folder.  

2.  As a workaround I tried to export the image using Save for Web (Legacy), but first without writing an Action.  I find that this is resulting in an image which is always 8192 px wide for any image I choose, despite resizing the image using Fit Image with different values.  See 2nd screenshot.  Why is this happening?  Thanks for your help in advance. 

The "Default Actions" are the only set available by default (duh) and they are almost useless, to me at least.

Removing this ability was an obvious error on Adobe's part, but also obvious after 5 years is that they have no intention of fixing their error. 

Same problem. My experience of Export is that it is never saved in the action list (like everything else is and should be), just ignored while other actions are progressively added to the list when recording. Save as is not an alternative option to use, as it creates a lot of dialog boxes that freeze everything while playing the action, ruining the whole automation process.
