What is BlinkCAD?

BlinkCAD is a free, browser-based viewer for DWG and DXF files — built for people who need to open AutoCAD drawings without installing AutoCAD or signing up for anything. Just drag and drop your file. In seconds, you can pan, zoom, and explore the drawing right in your browser. No software, no account, no waiting. What you can do with BlinkCAD:

1: Open DWG and DXF files online, instantly 2: Measure distances directly on the drawing 3: Toggle layers on and off to focus on what matters 4: Share any file with a private link — no login required for the recipient 5: Works on desktop, laptop, tablet, and mobile browsers

Who it's for: Contractors checking site drawings on their phone. Site engineers reviewing plans without firing up a workstation. Architects sharing concepts with clients who don't own CAD software. Project managers verifying revisions before a meeting. Anyone who receives a DWG file and just needs to see it.

Why BlinkCAD: Most CAD viewers either force you to download bulky desktop software, create an account, or make your files public by default. BlinkCAD takes a different approach — your files stay private, nothing gets installed, and you don't hand over an email just to open a drawing.

No AutoCAD license. No FastView subscription. No "free trial" countdown. Just open the file and get to work.

Currently in beta with ~85–90% rendering accuracy on standard DWG and DXF files up to 50MB. New features rolling out weekly — PDF export, password-protected sharing, and larger file support coming soon. BlinkCAD — open any DWG or DXF file in your browser. Free, forever.
