About .PK files
What a .PK file is, and what's inside it.
A PK file is a packed bitmap font created by the TeX typesetting system, not an audio file. It stores rasterized character glyphs for one font at one specific resolution (DPI). You will find PK files in your TeX Live or MiKTeX font cache; they are generated automatically and you do not need to open them manually.

Does opening a .PK 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.
