FontMod

English 简体中文 繁体中文

Simple hook tool to change Win32 program font. Works with some GDI/GDI+ or Qt based program.

Proven workable on Telegram Desktop, Kleopatra (Gpg4Win) and Mendeley Desktop.

Usage

Download FontMod{32,64,ARM,ARM64}.dll and rename to one of following:
dinput8.dll, dinput.dll, dsound.dll, d3d9.dll, d3d11.dll, ddraw.dll, winmm.dll, version.dll, d3d8.dll (d3d8.dll is 32bit only).
Then put in the folder of program exe.
User font: Put fonts in fonts folder to use them directly, don't need to install to system.

Config file

Will create FontMod.yaml on first run. Config file uses UTF-8 encoding. Support UTF-8 BOM.

    • key ("SimSun"): Font name to modify.
    • replace / name: Font name to replace.
    • size: Font size.

  • gdipGFFSansSerif, gdipGFFSerif, gdipGFFMonospace Replace GDI+ generic font family. (https://docs.microsoft.com/en-us/windows/win32/gdiplus/-gdiplus-fontfamily-flat)

  • debug Debug mode (Will log information to FontMod.log).

YAML supports anchors(&) and references (*) (Please refer to Wikipedia), this tool also supports not mandatory Merge Key function in YAML spec. You can reuse data like config file above, and don't need to copy multiple times like JSON.

If you want replace only CJK fonts and keep English font, you need to set key to CJK fallback font. This font may be different in different language environments. (For example in Chinese simplified environment is SimSun), you can use debug mode to find corresponding font.
