**WARNING**: This guide is for more advanced users as this guide uses linux!
Example:
As an example i downloaded all the Sayathefox (https://simpcity.su/index.php?threads/saya-the-fox.10438/) sets. ~3.8GB in size all together. Remove ONLY the metadata (things that don't impact image quality) shrunk the size down to 610MB!! More than 3GB of storage space wasted with useless trash data. (this data is useless as long as you don't use metadata to sort images)
Every .jpg image has a ton of metadata that are, in my cases, more than half of the filesize!
To remove this useless trash from your files get mat2 ( ).
To clean the metadata of a file you can do the following commands. I recommend the --inplace argument so that the file gets overwritten by the optimized version.
An example with a picture of Megumi Koneko:
The metadata of the file was close to 90% of the whole filesize! And the image quality was NOT touched by this operation!
To install the following tools use
Please note: Optimization is not equal to compression!
To optimize .jpg images use
To optimize png images use
The parameters are:
To recursively do this for a folder or all folders use the same asterisks * as above with jpegoptim.
A bit of theory: PNG shouldn't be used for cosplay shooting pictures. They make the filesize huge and are more suited for other usecases than photography.
You can use imagemagick's `mogrify` command to convert PNG images to JPG without much quality loss.
An example with a picture of SayaTheFox:
The example above was, at first as a .png, 104MB (!) in size, but after converting it and removing metadata it was a nice 6.5MB.
Ofcourse you could say "I want to keep the high quality of my .png image", but, atleast for me, the huge storage space wasted is not worth the small amount of quality gained.
A picture of Megumi Koneko as a full example (from 8.5 to 1.3MB!)
Sayathefox all cyberdrop sets currently on this site (From 3.8GB to 553MB!)
Hello my fellow hoarders. Most of your data is useless metadata.
Example:

Reduce image filesize further with optimization
To install the following tools use
