### What do you want to achieve?

In “Online font converter” I checked the checkBox of “Enable Font compression” but no significant reduction in size of the output fons .c file, same thing happened in SquareLine(by not add “–no-compress” to the “Custom” option box)

why???

this pic show the “use compress” output the “ui\_font\_fontRef36Compress.c”, and “not use compress” output is “ui\_font\_fontReg36.c”, they are the same size, why???

from this [I use "Online font converter" and "SquareLine" to gen font but the the compress not work!!! · Issue #98 · lvgl/lv\_font\_conv · GitHub](https://github.com/lvgl/lv_font_conv/issues/98)  
so the compress function not work well with 1bpp??

It seems so. I guess the conversion algorithm can’t compress 1bpp font further. You can ask for more info/details at LVGL forum…
