You sign a PDF in pdfMachine, send it off, and the recipient sees your signature… sitting on top of the page like a comment. Click it. Drag it. Delete it. Not exactly final.
Flatten it instead. The signature becomes part of the page — like ink on paper.
Sign, then flatten.
Drop your signature where it belongs, hit Tools → Flatten, and it merges into the document content. No more floating overlay.
Works for everything else, too.
Shapes, stamps, text, form fields — flatten merges any annotation into the page. The PDF looks finished, not marked-up.
Permanent on purpose.
Once flattened, recipients can’t click, drag, or delete what you put there. Save a copy first if you want to keep the original editable.
Looks like ink. Behaves like ink.
No more sticky-note signatures.
