Identify
You can call imagemagick in the command line by typing magick before and task here I used the command identify to describe the format and characteristics of one or more image files. 1.png PNG 773x409 773x409+0+0 8-bit sRGB 86243B 0.000u 0:00.005
By default, magick identify provides the following output: Filename[frame #] image-format widthxheight page-widthxpage-height+x-offset+y-offset colorspace user-time elapsed-time
The file is PNG format The size in pixels is 773x409 and each pixel is 8-bit The color profile is sRGB
Resize images
- first choose the image you want to resize
- then To resize the image we can use convert –resize ( then here we specify the size, for web 1280x720 is good size )
magick convert -resize 1280x720
Now I resized all my image and put them in a file to be uploaded and
images quality
also I can make the quality by type –quality and I can notice here that the image size drubbed from 224 KB to 226 KB
