Why
Acrobat is a subscription. Preview is almost enough.
Acrobat Pro costs about 240 dollars a year on a Mac, takes its time opening, and spends much of that time offering you an AI assistant. Preview is free and calm, and then a form you filled shows up blank on someone else's screen, or a save quietly strips the attachments, the reply threads, and the signature.
The middle has been empty for years: a PDF app that behaves like a system app, edits like it means it, and is bought rather than rented. Final is that app.
What it does
Reading is free. Finishing is the product.
Free means the whole reader: open anything fast, tabs, dual page, search, outline, go to page, filled forms, print. Good enough to set as your default PDF app and forget. One purchase unlocks the rest.
- Add text anywhere, styled, with real font embedding
- Highlight, underline, strike out, and reply, in a real comment list
- Comments open correctly in Acrobat, Preview, and Chrome
- Reorder, rotate, extract, and combine pages
- Compress with three honest presets and a before and after
- Recognize text in scans, entirely on your Mac
- Redact so the words are gone, not covered
- Sign, and keep a record of the signing
Signing
Every other app signs and forgets.
Preview, Acrobat's Fill & Sign, and PDF Expert all drop a picture of your signature onto the page and stop there. No record of what you signed, or when, or what the document said at that moment. When a signature is ever questioned, that record is the thing anyone actually asks for.
Final writes one. Alongside your signature it stores a fingerprint of the exact bytes you signed, the range of the file that fingerprint covers, the wording you agreed to, and the time your Mac believed it was, labelled honestly as your Mac's own clock. It also writes down what it did not record, because a record that overstates itself is worse than none.
You can check it yourself. Final prints the one-line command that recomputes the fingerprint, so the proof does not depend on trusting Final. All of it stays on your Mac. Final does not verify who you are. It records what you did.
The deal
$29.99, once. That's the whole pricing page.
Every serious PDF editor on the Mac is either a subscription or a “lifetime” license with an asterisk: version-locked, feature-gated, or revocable by email. Final's deal is written to stay simple. Pay once and the editor is yours. Minor updates are free. If a paid major version ever ships, owners get half off, forever, and recent buyers get it free. The app never deactivates, and nothing you make is ever locked away.
There is nothing to cancel, because there is no subscription. There is no account to close, because there is no account.
Private
Your documents never leave your Mac.
Every competitor's AI features run in someone else's cloud. Final's OCR and intelligence run on your Mac, using Apple's on-device frameworks. There is no telemetry to opt out of, and the app asks for no network access except the optional intelligence download, which you can decline and never see again.
How it's built
The save path is the whole product.
Rendering is Apple's PDFKit, the same engine as Preview, which is fast and faithful. Saving is not: every save Final writes is an incremental update appended to your file, so signatures stay valid and attachments, tags, page labels, and comment threads survive. Preview rewrites the whole file and drops all of that, which is why Final exists.
The editing engine is PDFium, the compressor is QPDF, both open source and license-free. That zero-dollar engine bill is the honest answer to how a serious PDF editor can cost forty dollars once: there is no annual SDK fee to pass along, and no cloud to keep lit.
Colophon
Built by Thesis Labs. Sibling to Galley and Kept.
In publishing, a galley is the proof of a manuscript. A PDF is what comes after: the finished thing, signed and sent. Galley reads the proofs, free and open source. Final finishes the documents. Kept remembers everything else.
