Long story short: Use GIMP for pixel-style texts. Check Billy Kerr's answer.
Compared with other tools, GIMP supports bitmap font, which is always pixel perfect.
For OpenType or TrueType fonts, you need to set hinting to full, as hinting gives useful information on how to display font clearly in a low resolution.
The original answer
In Windows, the ancient cmd.exe (conhost.exe for systems newer than Win 2000) still holds the ability to render bitmap font.[*] If there are not that many texts, simply press
Win + R, type in
conhost.exe, and then enter. Right click on the title bar, then select Properties.
Select "Font" tab then rolling down till you see "Raster Fonts" (aka 点阵字体). Choose the expected size and do a screenshot, using
Snipping Tool that comes with all the modern Windows releases from Win 7 or whatever you're comfortable with.
Delete the unnecessary black background. In the end you get crispy bitmap renders!
* Special note for high-DPI monitor users: You need to set monitor scaling to 100% if you don't want to bother with scaling down later!
