How do I use ImageMagick to convert webp file(s) to jpg in Linux (Ubuntu 22.04) terminal

I’m trying to convert a file with the magick command-line tool but I’m confused about what the error means and how to fix it.

I used the following code syntax:

magick <input>.webp <output>.jpg

I get this error:

magick: delegate failed `'dwebp' -pam '%i' -o '%o'' @ error/delegate.c/InvokeDelegate/1911.
magick: unable to open file '/tmp/magick-PGSTH7P1-9rGkrCgVJrwRyuTCjBoRkrJ': No such file or directory @ error/constitute.c/ReadImage/780.

The file I’m converting is in my current directory, and I’m not using a filename for which is already being used in the directory. I’ve made sure my spellings are correct, and my file types are correct as well.

There were no errors during installation either:

    I tested this again and found I needed:

    sudo apt install build-essential pkg-config webp libwebp-dev libwebp7

    Then you need to follow the remainder of the instructions to build from source:

    ./configure
make -j 4

sudo make install
sudo ldconfig /usr/local/lib

    The ffmpeg worked perfectly for me, assuming you have ffmpeg installed, which is the basis of a lot of video players and converter apps. If not:

    sudo apt install ffmpeg

    on ubuntu and many/most others.

    I scripted it to fix many webp’s at one time…
    —shell-code———————————-

    #!/bin/bash

    for file in *.webp; do

    ffmpeg -i "$file" "${file/.webp}".jpg

    done

    for file in *.WEBP; do

    ffmpeg -i "$file" "${file/.WEBP}".jpg

    done

    ADD more if needed…

    echo "========================================"
ls -als *.jpg
echo "========================================"
