# Changing default Image Compression

 * Hi. I have been testing out tweaking the default image compression with the filter
   below. As I understand it, the 100 value should turn off compression.
 * I found when I “scale” images down in the WordPress Image Editor the file size
   got much bigger than the original image file size. I thought it might stay the
   same, or get a little smaller, but not so much bigger.
 * 90 seems to work better, but I am just wondering why setting it to 100 would 
   actually make the file size get bigger? Thanks.
 * `add_filter( 'jpeg_quality', create_function( '', 'return 100;' ) );`

 * Setitng compression to 100 doesn’t disable it, it makes it 100% quality, which
   results in _very big_ files.
 * There’s no reason at all to set compression to 100. Especially if the images 
   that you’re uploading have been saved at a lower compression to start with, as
   seems to be the case here. A normal value for that is anywhere from 80 to 50 
   depending on image resolution and display size, so try something like that.

 * [@catacaustic](https://wordpress.org/support/users/catacaustic/) Thanks for the
   response. I read that before 4.5 the default used to be 90%, now it is 84%. Does
   that sound correct to you? Sometimes I need to have a bit crisper images. So,
   thinking 90% might work well.

 * I don’t know what the values were/are. I haven’t needed to worry about that so
   far. 🙂
 * As far as “crisp”, you’re better off with a larger pixel size scaled down to 
   display then to decrease compression. As am example, an image that’s set with
   70% compression that’s 600 x 600 pixels will normally look the same or better
   then an image that’s 90% compression that’s 300×300 when they are both displayed
   at 300 x 300 pixels.
