Concretely, encoder re-runs DCT quantiser pamhando factor iwe unosarudza, saka kuchengeta zvinobva coarser coefficients kupfuura kubva mashoma pixels — mavara echifananidzo kamwe chete kuchinja, uye 80 mhando ndeimwe yezvakanaka nguva. Nothing about it depends on you installing software: the job runs server-side and hands back a finished file.
