A standalone tool from EDC Built

Drawing Compare

Overlay two revisions of a drawing and see exactly what changed. Old in red, new in blue, unchanged in black, with the changed areas ringed for you.

Try it free in your browser What it does

Free in any modern browser. Nothing to install, and files are never uploaded.

Drawing Compare is a standalone desktop app. It is part of the EDC Built family, but it runs on its own. No account, no platform login, no upload. Install it and open two PDFs.

See what changed between two revisions

Overlay two revisions

Old drawing in red, new in blue, unchanged linework in black. The Bluebeam-style overlay, so a change is hard to miss.

Find changes automatically

Revision clouds ring what moved between versions. Sweep a whole set at once to see which sheets changed and jump straight to them.

Built for real drawings

Align sheets that don’t register, swipe between versions, nudge to sub-pixel, and export a layered PDF of the comparison.

Your drawings stay on your machine

Both files are opened and compared locally. Their contents are never sent to us or anyone else. Comparison works with the network unplugged, and the app contacts us only to check for updates and validate its licence.

Get the desktop app

Windows 10 or 11 (64-bit). A licence is required to run it, so contact us to get one for your team.

Download for Windows

On first launch Windows may show a “Windows protected your PC” notice because the app is newly published. Choose More info → Run anyway. Your IT team can also deploy it silently with a licence file; contact us for the details.
