| Where it stops | It will happily convert a font you have no right to serve on the web — the licence check is entirely yours. | Each page does one narrow job, so anything multi-step means chaining tools by hand. | Ad-heavy, and because everything runs in the tab a multi-gigabyte archive is limited by your browser's memory. | Ad-dense and visually stuck in 2011, and some reference tables have not been revised in years. |
