Font size problem in pdf? Online etc.

The fonts in pdf can be enlarged without distortion, why? Is it the font library or other reasons?

The font display in pdf uses the font processing library directly, and the api is completely unnecessary, so it can be very accurate

I also want to know why the fonts printed in PDF format are so small and blurry, can they be modified through settings or other methods? Ask a master for guidance
