- The page describes a seven-edit demo using embedded Georgia and Verdana, a shaded table, and right-aligned amounts.
Field notes
The described workflow starts with a text-based PDF upload, then editing directly on the page and downloading the result. The site says it checks output by reparsing, rerendering, and comparing it with the original, and that it will flag edits it cannot make safely. Its example session features a shaded table, right-aligned amounts, and embedded fonts; the page also states a 100 MB file limit. These are homepage descriptions, not independent tests of the editor.
