Hello,
I have a question about webp format in photoshop. I want to export many files at once in webp format in Photoshop but I don't find the webp format in photoshop options. Is it normal?
Best regards

WebP was introduced in Ps2022 as a native Save As (a Copy) option, not under Export As/Quick Export. You will either need to set up a batch action to save directly to WebP or to convert from PNG to WebP or use a custom script to save or convert to WebP.
In previous versions, there were 3rd party plugins from Google or other developers.
Update: A GUI version of the script here...
__________
Here is a batch script to save as WebP.
Features:
* Optionally run an action (edit the code to enable)
* Optionally ask to overwrite existing files (edit the code to enable)
* Set an input and output folder
* Set supported input file types (edit the code)
* Automatically converts non-RGB mode to sRGB space, 8 bpc
* RGB files automatically converted to 8 bpc
* Option to convert RGB mode to sRGB space (edit the code to enable)
* WebP lossy

I need a script file that can do this batch, do you have an example?
Hi @Stephen Marsh,the script is working very nice. The only thing i'm trying to add is resizing the file to 600x600 pixel before it saves. I can't seem to get this fixed. Would you have a suggestion on how i can make that work?
By @Toby25396707l0ai
You could add a line of code to resize:
https://theiviaxx.github.io/photoshop-docs/Photoshop/Document/resizeImage.html
activeDocument.resizeImage(UnitValue(600, "px"), UnitValue(600, "px"), null, ResampleMethod.BICUBIC);
This will obviously distort a non-square image.
...how would I have the script resize theimage on longest edge? I want the longest edge to be 1920px Thanks again !

Try this updated 1.2 version (the fit image uses Bicubic resampling, but this could be changed, also added a step to force RGB mode to support WebP):

v1.1 - 11th January 2024: Added a "fit image" to 1920px step
v1.2 - 10th February 2024: Added an explicit step to change to RGB mode for non-RGB images
