e.g. if i want to export a jpeg at 80%, how do i do that in Sketch.app? it appears to export at 96% by default.

edit:

there is a much more simple way of doing this. when you hit export and the file prompt shows up, click options, and you are presented with options including quality

enter image description here


after some investigation, i discovered you are able to do this via os x's command line defaults tool:

to lower the quality:

$ defaults write com.bohemiancoding.sketch3 JPGQuality -string "0.6"

you can reset it to the default of 0.9:

$ defaults write com.bohemiancoding.sketch3 JPGQuality -string "0.9"

i also learned that a variety of things can affect JPEG quality, so the percentage i set in sketch doesn't line up exactly with the quality reported by imagemagick's identify tool.

you can see Sketch's configurations by running this command:

$ defaults read com.bohemiancoding.sketch3

  • Amazing! Is there any way to set these defaults per-project?

  • @JacobFord i found a much more simple way of doing this that would probably suit your needs (click "Options" on the file chooser screen)

  • Oh! Well that was obvious.

  • To see your current .jpg setting in sketch, do what @PETER said (sweet!), but tack this on to the end of your terminal command defaults read com.bohemiancoding.sketch3 | grep -i jpg That returns any lines with "jpg" in them. The -i option makes the search case insensitive. Commented Aug 18, 2016 at 2:32
