I have a folder full of name*.jpg files.

I found that Imagemagick convert is the right 'tool' to resize my images.

The command I'm using is

convert name*.jpg -resize 2000x1500 name*.jpg

Problem is, that it uses all my RAM (8 GB) so my PC hangs and after a while it starts doing something but the output files are not resized.

Does anyone know what the issue could be?
Size of all files is about 200 MB.

  • also tried other output names. Same result :/

  • convert does not accept multiple files as input or output. Also, if you want to overwrite orginal files use mogrify instead of convert.

    @OcK More than one package can install a convert command in /usr/bin. You may be able to get more answers and/or an explanation of what happened if you edit this question to include the output of lsb_release -a, type -a convert, apt list --installed '*magick*', and namei /usr/bin/convert.

Instead of:

convert name*.jpg -resize 2000x1500 new_name*.jpg

The following worked for me: (loop on every jpg image in the given folder):

for file in *.jpg
    convert "$file" -resize 2000x1500 "new-$file"
