Frequently Asked Questions

Are these tools really free?
Yes. Free, no signup, no email, no watermark. They are a thank-you set from the team behind Ncored, a fast desktop PDF editor for large construction drawings.
Do my files get uploaded to use these tools?
No. Every tool runs in your browser on your own device. Your files are never sent to a server, never stored, and never seen by us, unlike most online PDF tools that upload your file to process it in the cloud. That makes these safe for confidential and NDA documents.
What if I work with heavy CAD drawings every day?
These browser tools handle the quick jobs. For the daily work of opening and marking up a 50-200 MB+ AutoCAD, Revit or ArchiCAD export without your PDF tool freezing, that is what we built Ncored desktop for, Windows and Apple Silicon Mac, with a free 14-day trial at ncored.com.
