I want to use a function that you indicate in the optimization manual.
add_filter ('jpeg_quality', create_function ('', 'return 50;'));
And they also suggest “50%”, and that is a trocater the value to provide a desirable quality.
Also, it says to use the “Force Regenerate“, after put the code above in the file functions.php
The question is:
If I put ‘80% ‘and do not get the results I want, can I try again with another value (example: 50%)?
The image will not lose more quality. Why was it compressed the first time?
That is, every time I use this function, the image would get worse quality?
Thank you

Hi,
It may be required to remove the code and regenerate again in order to recreate the original thumbnails quality. You could for example create a testing sub-domain and install the theme there and make tests. This would be useful when trying different things on the website, without many risks.
I found some more info about it here
