A FEW USEFUL ANSWERS
Frequently asked questions
Is there a truly free online CAD editor?
+
Yes. Viewing, editing, conversions, batch processing and watermark-free exports are free. Daily limits apply; there is no payment or subscription step.
Can I open DWG files online without AutoCAD?
+
Yes. Open your DWG in the viewer to pan, zoom, switch layers and measure. You can then edit the drawing or export a PDF in the same workspace.
What is the difference between online CAD and AutoCAD?
+
Online CAD describes where a tool runs. AutoCAD is a specific Autodesk product with desktop, web and mobile offerings. CADEditor focuses on viewing, converting and editing drawings in your browser.
Do I need to install anything to use CADEditor?
+
No. Open the site in a current browser. A free account is needed only for cloud storage, and API access uses an API key.
Are my files kept private?
+
Viewing, converting and editing happen in your browser. Your drawing is uploaded only when you confirm Share or Save to Cloud. Local history is off until you choose Save on this device.
Can I continue a drawing later?
+
Choose Save on this device to keep local history, or Save to Cloud to upload a copy to your free account. Local saving is off by default. You can remove either saved copy whenever you choose.
