JPEG Quality Settings


By default WordPress forces all thumbnails be set to a quality level of 82. But what if you want to change that? Sure the
jpeg qualtiy filters exist if you want to code in a value, but they affect all JPEG thumbnails which may not be desirable.

For example you might want a blog background to be of a lower quality, hence lowering the filesize and increasing the speed
of which the page loads.

By using the JPEG Quality Settings plugin you can now customize the quality based on whatever values you want.

Does this affect any existing thumbnails?

No, you will need to install a plugin to regenrate thumbnails. Many good free options exist.

Can my theme provide default options?

Yes! By taking advantage of the filters installed. For example:


add_filter(‘jpegquality_my_blog_size’, ‘mytheme_myblogsize_quality’);

function mytheme_myblogsize_quality(){
return 10;
