PDF markup software for construction, in your browser
Redline drawings, add clouds and callouts, drop symbols, and measure to scale on any PDF plan set. TRACEBUILD Lite gives you a full construction markup toolkit in the browser, with nothing to install and no credit card, free while Lite is in early access.
Your drawings never leave your device. Markup and measurement run locally in the browser.
A full redline toolkit, not a viewer
- Clouds, callouts, and text for revisions and RFIs, with a rectangular drag to size the cloud exactly.
- Highlights, shapes, arrows, and ink for fast markup over any sheet.
- Stamps and a CAD-style symbol library covering valves, fittings, HVAC, electrical, plumbing, fire, and more.
- Snap to geometry so lines and symbols land on the drawing, not near it.
- Whiteout and redaction to knock out or cover content cleanly.
- Rotate, align, and distribute markups with handles and a right-click menu.
Markup and measurement in one place
Most PDF tools make you choose between annotating and quantifying. TRACEBUILD does both from the same toolbar. Set the scale once, then switch between redlining a detail and pulling an area, a length, or a count without leaving the sheet.
Measure to real scale
Areas, lengths, and counts in real feet or meters, imperial or metric, with running subtotals.
Any PDF, any size
Letter specs to full size drawings, vector or scanned, all in the same set.
Find anything fast
Instant text search across sheets, visual search by image, and OCR for scans.
Print and save clean
Flatten markups and save or print, or export the marked up set to share.

Common questions
Can I measure to scale, not just annotate?
Yes. Set the scale from a known dimension or a standard preset, then every area, length, and count reads in real feet or meters. Markup and measurement live in the same toolbar.
Does it work on scanned drawings?
Yes. You can mark up and measure any PDF, including scanned plans, with built-in text search and OCR when there is no text layer.
Are my drawings uploaded?
No. Markup and measurement run on your own device in the browser. Your PDF is not uploaded to use these features.
What does it cost?
TRACEBUILD Lite is free in the browser during early access. A Windows app, TRACEBUILD Pro, is coming soon with estimating, on-device AI, and more.
