Thanks fmw42. I get it. So, for a given png/jpeg image, if I always convert that to a jpeg and compress + blur it, can I get it to below 20kb? What would my convert command look in that case? I have tried jpeg:extent, but most of the times thats not bringing the size down to my expected size. I am ...

Hi All, I pretty new to Image Magick and working on a solution to create a low-quality placeholder image for any given image (jpeg/png/gif). My main goal is to get a blurred image which will be of the same dimension of the original image but very very low sized. Let's say a placeholder image of a ...

Cool. Thanks. It works.

I'm probably stuck in the last part of the issue where I am trying to get the size down for the generated JPEG image.

Thanks GeeMack.

I am getting this when I run this my terminal.
convert original.png -set option:distort:viewport %[w]x%[h] -resize 1x1 -distort SRT 0 otter.png

zsh: no matches found: %[w]x%[h]

I have tried to compress the size of the output file with defining an extent for jpeg. But that does not seem to be honored it seems.

I can get the placeholder image created with a size ~26kb for JPEG and below 1kb for a PNG. Is there any way ...

Also,
I think I need to downgrade IM version to ImageMagick 6.7.8-9 (for some organizational and OS requirements).
So, want to make sure the magick command will work on that version too.

Sorry. Being dumb here.
It says

no matches found: %[MYSIZE]

when I ran the command.

Thanks snibgo!
This works perfectly.

Few things I am missing with this Is there any way to know/calculate the dimension of original.jpeg and pass it on to scale instead of hardcoding 2400x1474?

Hi All, I am very new to Image Magick and have used the basic image magick commands. I am currently working in a use case where I want to get the background color of a given image and use that to create a placeholder image (low quality very small image but with the same dimension of the actual image ...
