About .MCF files
What a .MCF file is, and what's inside it.
An MCF file is an internal resource file associated with PTC Mathcad, used to support rendering of mathematical notation. You do not open it directly. Mathcad reads it automatically. The .mcf extension is also used by completely unrelated programs (Embarcadero FireMonkey, MediaCoder, Pajek), so the first step is identifying where your file came from.

Does opening a .MCF file install it on my computer?
No. The font is loaded only inside this browser tab and disappears when you close it. Nothing is installed or uploaded.
How do I know which languages a font supports?
Open the Languages tab. We check the font's character map against the letters each language needs, for example ą ć ę ł ń ó ś ź ż for Polish, and show what's missing.
What are OpenType features?
Optional typographic extras built into a font: ligatures, small caps, old-style or tabular figures, fractions, stylistic sets. Switch them on and off in the Type tester to see what your font offers.
Can I use this font on my website?
Technically yes. Copy the @font-face CSS from the side panel. Legally, check the licence shown in the font info: many fonts are free (SIL Open Font License), others need a web licence.
Why does my Type 1 font look like an image?
Browsers can't use Type 1 fonts, so we render a specimen with Ghostscript instead. You can still type your own sample text and zoom in.
