How signing should work on a Mac.

The files you sign — engagement letters, vendor contracts, approvals, NDAs, application forms — are usually the most sensitive ones you handle. So the signature is only half the story. The other half is that the document never had to leave your Mac to get signed. TruePath PDF is built for both.

1

Open the document locally, not in a queue.

Every operation runs on your Mac — no account, no cloud upload. A signed contract usually carries names, addresses, deal terms, or banking references, so the cleaner default is to open the PDF from your own files and keep it there. The home view starts from your local documents, not a hosted workspace.

Read it before you sign it.

Signing is the last step of a review, not the first. TruePath PDF is built around fast native reading, search, and outline navigation, so you can actually check the clause that changed and the date field someone missed before your name goes on the page.

Create your signature once. Reuse it everywhere.

Draw your signature by hand or with the trackpad, and save it to your signature library. Next time you don't start over — pick the saved one and place it. Keep more than one on file if you sign with different marks for different things.

Place it, save locally, and share the standard PDF.

Drop the signature where it belongs, save the document, and you have an ordinary PDF you can send wherever it needs to go. If the file is sensitive, the same app handles passwords and permissions locally, so you can lock it down before it leaves your Mac.

Why sign here instead of a cloud service.

Most signing tools are built around routing your document through someone else's servers. TruePath PDF is the opposite: the file, the signature, and the saved result all stay on your Mac.

Handwritten or trackpad signatures

Create your signature by hand or with your trackpad — your own mark, not a typed font pretending to be one.

A reusable signature library

Saved signatures stay on file, so you create one once and place it on the next document in a couple of clicks.

Local-only, no cloud upload

The document never leaves your Mac to be signed. No account, no hosted routing, no upload step for a file that shouldn't travel.

Single signed binary in Apple's sandbox

A single notarized binary inside Apple's sandbox — a native Mac document tool, not a web service wearing a Mac icon.

Standard PDF in, standard PDF out

The signed document saves as an ordinary PDF, so it opens for whoever you send it to.

Frequently asked

Straight answers on how signing works, where it runs, and how it's licensed.

Can I sign a PDF in TruePath PDF?

Yes. Create a signature by hand or with your trackpad, save it to your signature library, and place it on any PDF. Signing is part of the Pro tier; reading and annotation are free, and after the 14-day trial the Pro actions unlock with a one-time license.

Does signing stay on my Mac?

Yes. Every operation runs locally — no account, no cloud upload. A signed contract or form usually contains names, deal terms, or identity details, exactly the kind of file that shouldn't travel through a hosted service just to collect a signature.

Can I reuse a signature?

Yes. Saved signatures live in your signature library, so you create one once and reuse it across documents instead of redrawing it every time.

How is this different from DocuSign?

Services like DocuSign route your document through a hosted cloud workflow. TruePath PDF keeps the file on your Mac: you sign locally and share the resulting standard PDF yourself.

Is TruePath PDF on the Mac App Store?

Not yet. TruePath PDF is available today as a direct download — a notarized, Universal app you get straight from us, with a free 14-day trial.
