[Bug]: WebP format is still JPEG

[uwe-schwarz]

Operating system

macOS Ventura 13.0

Publii version

Bug description

Selecting "Convert to WebP format" only changes the file extension of the generated responsive images, they are still JPEG and have the same size.

Steps to reproduce

1. Select "Convert to WebP format"
2. Regenerate thumbnails

Relevant log output

No response

Maybe related. How do I use the Sharp library for generating thumbnails? I am on OSX.

[uwe-schwarz]

Sharp library was preselected for me, never changed it. I started using Publii somewhere around 0.40, maybe 0.39.

@uwe-schwarz - so after regenerating thumbnails you still have JPGs? BTW please make sure that you mean responsive thumbnails with prefixes like -xs, -xl etc. Because the original images remains untouched.

@j0el - you can change it under app settings https://getpublii.com/docs/publii-global-settings.html - it is located under "three dots" menu in the right upper corner.

@uwe-schwarz - thank you for spotting this :) I have tested this feature, but now I have discovered that the code was working only when thumbnails has been cropped. The fix is ready - we will release it probably at 7th November :)

Got it. All my thumbnails are now WebP! Thanks for your help.
