Fastest way to exporting as webp in photoshop

So, where are you at with this?

As you want to have the ability to manually name files and handle overwriting files of the same name, the easiest way is to use a script which uses the native Save a Copy interface, defaulting to use the active document path. This means that the WebP option window will pop up every time as that is part of the Save a Copy process, just as the Save a Copy dialog that you need for file naming flexibility is also a part of the same process. 

If you don't wish to have the WebP options dialog come up, then a modification of the script would be required to disable the native dialog and add a prompt for providing a filename.

Hi

You could :

1. Record an action for saviing as webp
2. Use this action in the file > scripts> image processor (4)

Actions and Scripts are the common forms of automation where keyboard shortcuts can be applied... That being said, more info would be required to offer more than generic advice.

General items for consideration (some may or may not apply to WebP)?:

* WebP compression - lossless or lossy. If lossy, what quality % value?

* WebP metadata, exclude or include? If include, XMP, EXIF and or Photoshop?

* Save As or Save a Copy?

* File name? Use the current file name or something else (prefix, suffix etc).

* Save location? Same as the original file or to a fixed/static location such as the desktop?

* Silently overwrite files with the same name/extension or prompt to overwrite?

* Convert to 8-bpc?

* Remove alpha channels?

* Convert non-RGB images to RGB?

* Convert non-sRGB images to sRGB or something else such as P1?

* Something else that I haven't considered?

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
