I do not think it is an IM bug, but a bug in your installs. I strongly disagree with this. In what way did I make a mistake in my installation of ImageMagick on Ubuntu through the official repositories? In what way did I make a mistake when I installed ImageMacik on macOS through Homebrew, on two ...

I agree with fmw42, something is wrong with my install of ImageMagick on macOS, and with my install of ImageMagick on Ubuntu, and therefore there is a bug with ImageMagick not correctly interpreting the `-set filename:f %t` options even though it does correctly convert image files to WebP. On macOS ...

I've double-checked, but I'll check again that it is indeed converting to WebP. Even if it isn't converting to WebP, this is still a bug because ImageMagick should understand the `-set filename:f %t` options. On Ubuntu, here is the result of this command that examines the first few bytes of the file ...

I disagree that imagemagick is failing to convert the image to WebP in my case, @fmw42. It clearly is working, the file generated is a WebP image that works everywhere that I expect WebP images to work, and the `file` command on Ubuntu clearly identifies it as WebP: $ file example.webp example.webp ...

THanks for your suggestion snibgo. This is the output on my macOS machine as well as on my Ubuntu machine: $ convert -list format 2>&1 | grep -i webp $ It doesn't list WebP for some reason. However, conversion to WebP does work! $ convert example.png example.webp $ ls *.webp example.webp $ identify ...

Putting double-quotes around "%t" makes no difference, I tried. It doesn't surprise me that it makes no difference, as the percent character is not interpreted by the bash shell, and therefore doing %t or "%t" is identical and the process being run cannot distinguish between the two cases.

To convert an image from one format to another, changing the extension, you can do this: $ convert example.png -set filename:f %t '%[filename:f].jpg' $ ls example.jpg example.png However, if I try the same technique when converting into a webp image, this is the result: $ convert example.png -set ...
