How to convert fonts into binary file?

I want to convert the font(for example Barlow font ) into a binary format. So, that I can store it in an external flash as a VFAT file instead of an internal ROM as a C-file. Like there is an option in LVGL for converting images into bin format. Is there any similar method or tool for the font in LVGL?

Yes there is the lv_font_conv tool that you can use to create a binary font file too.

That tool is used for the online font converter too, but the option to save as binary file is not exposed in the Web interface.
