I work a lot with graphics and with the new .webp extensions I can't just right-click on an image and pick my graphics program from the 'Open with..' list. How can add the .webp extension to the settings so I get my graphics program on the list? Thank you!
Boot your Mac into Safe Boot mode and then reboot normally. Safe Boot rebuilds the LaunchServices database and should add your .webp discovered graphics application (GIMP) to the Finder's Open With sub-menu.
"Open With" chooses an app.
If you right click a .xls file and choose "Open With" and select Excel, that app will open that file.
If you do a "Get Info" on a file, you can change the default app to open it.
A properly installed app should be there without any special action. You may have to use the app for while for your system to "learn" it's there. I have noted some apps show up later than others
Have you restarted lately? If not, please do so. If no joy, start in safe mode, let it sit for maybe ten minutes, then reboot normally and retest.

Yeah, tried the SafeBoot but didn't solve it, I think Barney is correct, the app needs to tell the OS it can handle the webp files. Still, would be nice to have a manual option for this. I'll contact GIMP and let them know to add the new file format. Thank you all for the suggestions!
After doing some research I found a couple of quick workaround for this. One suggestion was to click-drag the file to the app in the dock you want it to open with while holding down the [option]+[command] keys, this will force the app to open the file even if it doesn't recognize it. Option 2 (which I chose to do) is to create a QuickAction item which shows up on the right-click menu under QuickActions.
Thank for the response ku4hx, however I do not want to change the default app because I use Preview to quick preview images (a LOT of them) each day, just want to add my graphics program as an available option on the right-click menu so if an image needs editing I can quick open it with the graphics program. Right now if I want to edit a .webp image I have to go into the graphics program and try to find that picture from there making it time consuming and ineffective.
Here is an example, Model 0049 is a .jpg file, Model 0367 is a .webp file. If I right-click the .jpg file I get a long list of available apps, if I right click the .webp file the list is very limited. I am looking to add my graphics editor to this list for the .webp file.
Your graphics editor must have been written to tell the OS that it can handle .webp files. You can't add an app to that list. When an app is installed, it registers everything it can open using the info.plist file in the app package.
