Imagemagick

To convert all files to jpg, the magick mogrify command can be used with the -format option to convert png, webp, and gif files to jpg. Additionally, in Powershell, the rename-item command can be used to rename all jpeg files to jpg by changing the file extension. The magick mogrify command can also be used to resize all jpg files, with options to specify a maximum width and height, such as -resize '720x720>', or to resize to a specific width while preserving the aspect ratio, such as -resize 960. Other resize options are available, including resizing to a specific width and height, such as -resize 960x528, which can be applied to jpg or other file types, including png.
