PRODUCT FACTS
Redline PDF, at a glance.
Redline PDF is a browser-based PDF drawing review, markup and takeoff workspace for individual architects, engineers and reviewers.
What does Redline do?
Review drawings with clouds, callouts, text, stamps and measurements. Organize markups with subjects, status and replies. Reopen saved drawings in your private account workspace. Save reusable signature marks; these are visual marks, not certificate-based digital signatures.

Can I delete an existing revision cloud?
If it is a supported PDF annotation, import it as a markup, select it and delete it. If it is flattened into the page, selection depends on the source objects. A scanned cloud is pixels, not an editable annotation. Read the PDF editing guide before changing a drawing.
Are PDF measurements automatically accurate?
No. Calibrate each sheet using a known dimension, then check a second dimension before taking quantities. A printed scale can be wrong after resizing. Follow the calibration guide.
Where are my drawings stored?
Saved drawings belong to your account and are encrypted on the server. See the privacy policy for storage, retention and account deletion details.

Try it on the sample drawing
Redline runs in the browser — nothing to install. Open the demo to try tools on a sample drawing. Demo edits are temporary; your own files, saving, signatures, exporting, printing and downloads come with the seven-day trial, which takes no card. After it you keep Redline Free, or choose Pro at $15 a month or $150 a year. Compare the plans.
