hello
i'm using centos 7 for my website and i tested my site with many tools and they say to compress images because of site slow loading
Is there any package that will compress images by specifying folder? or by using cron or any method?
Thanks
Regards.

What sort of image files are you using? Almost all of them are already compressed so compressing them again will just waste cpu time. All jpeg, gif, png images are already compressed.

EPEL has jpegoptim-1.4.4-1.el7.x86_64
This is about recompressing your existing image files so that they take up less space so not really anything to do with httpd at all except that it's the guy reading them and delivering them.

For png you can use : optipng or pngcrush, pngnq, pngquant. I recommend optipng. Go to 'optipng --help' to get more info of compressing.

This is about re compressing , this is what i need.. all users that will use my website to upload their ad's for sale will go to a folder that i need to re-compress them to make them loading fast for future use
what you think ?

Hello h0feer,
Install jpegoptim using EPEL:
It optimizes images without quality loss. For PNGs, optipng and pngquant are great for compression:
For Automate compression with a cron job script:
Code: Select all
bash
Copy code
jpegoptim --max=85 /path/to/images/*.jpg
optipng -o7 /path/to/images/*.png
This setup ensures images uploaded for ads are automatically optimized for fast loading.
or if you looking for third party image optimization tool such as
jpeg compressor with instant delete option right after the compressed the file. I think this guy using same software.
This script based on CentOS 7.
Good luck
