Is there a table that gives the compression ratio of a jpeg image at a given quality?
Something like the table given on the wiki page, except for more values.
A formula could also do the trick.
Bonus: Are the [compression ratio] values on the wiki page roughly true for all images? Does the ratio depend on what the image is and the size of the image?
Purpose of these questions: I am trying to determine the upper bound of the size of a compressed image for a given quality.
Note: I am not looking to make a table myself(I already have). I am looking for other data to check with my own.
