Most PDF tools do one thing well: combine, split, watermark, redact. The Modifier is the opposite. It is the editor you open when you do not yet know exactly what the document needs. Drop in one PDF or several, then mix and match operations: rearrange pages, draw on them, type notes onto them, highlight a clause, drop in page numbers, delete the pages you do not want, and download a single clean result. Everything happens in the same canvas and the same browser tab, with no round trips between five different tools.
The Modifier is meant for the times when a single specialized tool would force you to do the same edit five different ways. Filling in a "non-fillable" PDF form by typing on top of it. Marking up a draft contract with comments and highlights before sending it back. Stitching a cover sheet, a contract, and an addendum into one packet you can hand off as a single file. Prepping a long manual for review by removing the pages that do not apply and adding page numbers to the rest.
The entire editor runs in your browser. The PDFs you load are never uploaded, never sent to a server, and never seen by anyone but you, even when they contain contracts, internal documents, or anything else sensitive. Close the tab and the files are gone from this tool entirely.
