You can use Windows Imaging Component.
[VB6] Intro to the Windows Imaging Component (WIC): Scale and convert to JPG or PNG
If you're on Windows 10, it supports WebP natively, but if you're on Windows Vista or 7, you'll need to install a codec:
Here is one from Google that I use. You'll also be able to see previews in the Windows Image Viewer and in Explorer (in e.g. the Preview pane in my ShellBrowse control). Note that after installation you have to restart your computer before WIC will recognize it.
IT'S SO FUNNY,Quote:

No, WebP images are ~30% smaller that JPG at *same* quality settings. Your "benchmarks" are probably flawed yet again if you get threefold decrease (hint: quality settings).Quote:

Hint: JPG qualtity setting at 80 is *not* the same as WebP quality setting at 80.
More hints: libjpeg-turbo qualtity setting at 80 is *not* the same as WIC quality setting at 80 because each library interprets its own JPG quality settings differently.

He provided two photos.(webp,jpg)
wic save jpg use 60%,80%,100%
No, this is "Copyright (c) 2010, Google Inc" and both images are not compressed with the same quality settings and/or their choice is biased because these are shipped by the "vendor".Quote:

You started this thread about WEBP graphic files.
And then you suddenly talk about adding files to a Zip archive.
Just keep it to one topic per thread
