PDF Markup Tool is built for architects, engineers, and contractors who need to redline drawings, review coordination comments, and send out an annotated PDF without handing project files to a remote service.

Everything needed for free drawing review

Open a sheet in Chrome, Safari, Edge, or Firefox and work with the same local-first workflow from the first markup through export.

Full markup toolset

Line, polyline, polygon, rectangle, text, cloud, callout, arrow, ellipse, highlight, and ink tools are all available in the free browser workflow.

Measurement to scale

Calibrate the drawing scale once, then measure length, area, and perimeter directly on the PDF for quick checks and takeoffs.

Private and local

Files are processed in your browser on your device and are not uploaded. You can keep markups local from open through export.

Export what you reviewed

Export an annotated PDF for the field or design team, then export the markup list to CSV for downstream tracking.

Made for drawing review

Use it for submittals, RFIs, punch review, and design coordination when the job is to get comments onto sheets quickly and clearly.

Starts instantly

There is nothing to deploy to a workstation. Open the URL, choose a PDF, and start reviewing in the browser right away.

Open a drawing and start marking it up

Launch the tool, keep the file on your machine, and send back an annotated PDF when the review is done.
