What you can do on day one
Calibrate scale and measure distances, areas, and angles on real PDF drawings.
Mark up punch items, design comments, and review notes without bouncing between tools.
Try the full app free on Mac or Windows, then buy once only if unlimited hand-created measurements will save you time.
What PolyPDF helps you do faster
Designed for architects, engineers, contractors, estimators, and reviewers working from PDF drawings.
Mark up reviews without tool switching
Add callouts, highlights, shapes, and notes so site issues, design comments, and decisions are easier to communicate.
Buy only after it proves itself
The free download — Mac or Windows — lets you test PolyPDF on live work before you unlock unlimited hand-created measurements.
See current PolyPDF workflows
Six distinct dark-mode states from the native-maximized current development app, shown full-frame on owned or rights-cleared validation sheets—not mockups.
Review Symbol Search matches before counting
Box a representative symbol, inspect the candidates, and commit only the matches you accept. This genuine search result shows 5 matches, all 5 selected, with Count 5 ready.
Measured quantities stay tied to the sheet
The Records view keeps the visible quantities beside their drawing context. This fictional takeoff shows 14 items: a 540 sq ft area, a 30 ft length, and 12 supply-diffuser counts, with matching rows in the Markup Table.
Reviews and RFIs, straight on the sheet
A rounded RFI callout, an In Progress revision cloud, and a Completed verification rectangle remain connected to three matching table rows and their review comments.
Calibrate, then verify a second span
The Page Scale panel confirms 1/4 inch = 1 foot, or 18 PDF points per foot. A second known span on the fictional sheet reads 12 feet before the scale is trusted for takeoff.
Built-in MUTCD sign toolsets
The built-in MUTCD Regulatory reference chest is open with a genuine R1-1 STOP annotation selected inside its labeled target. The owned fixture is a fictional validation sheet, not a field plan.
Plugin output stays editable on the PDF
Development evidence: the AISC Steel Sections plugin inserted a selected W24×55 vector into the fictional target. This is not a public-availability promise: AISC data redistribution rights remain unresolved, PDF Maps is blocked pending a production-compliant geocoder and request pattern, and Professional Seal Maker still requires human jurisdiction review. No map or seal output is claimed in this frame.
Desktop software for Mac and Windows.
PolyPDF runs the same engine as a desktop app on macOS and Windows, focused on everyday review, markup, calibration, and takeoff workflows construction PDFs demand.
One app, both platforms
The Mac DMG and the signed Windows installer ship the same engine at the same version — open drawings directly, no VM or browser-only workaround on either side.
AEC takeoff basics
Distance, area, perimeter, angle, count, and dimension tools are built around the PDFs architects, contractors, and estimators already exchange.
No annual seat timer
Try real documents for free, then unlock unlimited hand-created measurements with one direct license that covers up to 3 computers.
There is nothing to decide until you hit the cap.
Markup, review, calibration and Symbol Search auto-count stay free for as long as you want them. The only wall is the fourth hand-created measurement in a document. That is the moment Pro is for, and it costs $49.99 once.

FAQ
Short answers to the buying questions that usually block a download.
What can I do before I pay?
You can download the app free on Mac or Windows, open your own PDFs, calibrate scale, use the markup tools, place up to 3 hand-created measurements in every open document, and use uncapped Symbol Search auto-count. That gives you a real-world test before you buy.
Does one license cover both Mac and Windows?
Yes. A license activates PolyPDF on up to 3 computers in any mix — three Macs, three Windows PCs, or any combination.
What does the $49.99 license unlock?
The Founder's License removes the hand-created measurement limit. Use PolyPDF 1.x forever on up to 3 Mac or Windows computers. Every PolyPDF 1.x update is included. Future major versions may be optional paid upgrades.
Is this a subscription?
No. The PolyPDF Pro Founder's License is $49.99 once. There is no annual renewal, recurring maintenance bill, or subscription timer.
What happens after I buy?
Checkout is handled securely by Stripe. Your license key is delivered by email, and you paste it into the app once — on Mac or Windows — to unlock unlimited hand-created measurements.
How do I activate the license key?
Open PolyPDF and choose Upgrade to PolyPDF Pro — it is in the PolyPDF menu on Mac (Command-Shift-L) and the Help menu on Windows (Ctrl-Shift-L). Paste the key from your email, which looks like PPM-XXXX-XXXX-XXXX, and click Activate. There is no restart and no reinstall, and the drawing you have open keeps everything already on it.
How do refunds work?
Purchases are handled through Stripe and PolyPDF support. Refund requests are reviewed under the refund policy, which also covers your statutory rights.
