The file fieldtype automatically reduces img quality to 75% by default. The transform tag does the same. If you use both (why would you not use {{ transform }}?), you end up with 56.25% (if my math is wrong, I blame my sleep deprivation).
I disapprove ಠ_ಠ, but I still love you.
Either a global override setting or default to 100% would be very much appreciated.
Thanks.
Love, Curtis (and people I work with)
