Pre-import validation

Received a corrupted email attachment? Wrong revision? Inspect the file in seconds — if it opens here, your team can proceed with review or conversion.

DXF exchange file QA

Corrupt or truncated DXF exports waste import time. Open ASCII or binary DXF here first — if CadPeek renders geometry and layers, most downstream BIM and takeoff tools will too.

FAQ DWG file inspector DXF validator

Common questions about our free online DWG file inspector DXF validator tool.

Can I see the AutoCAD version of a DWG?
The sidebar shows file metadata including version hints, unit settings, layer count, and text entity totals after parse.
What if the file fails to open?
Corrupt or password-protected DWG files may not parse. Try asking the sender for DXF export or an earlier DWG version.
What does DXF validation check?
Whether the DXF opens, geometry renders, layers load, and text entities appear a quick pre-import sanity check.
Binary or ASCII DXF?
Both are supported. If one variant fails, ask the sender to re-export as ASCII DXF from AutoCAD.
Do I need AutoCAD installed?
No. All tools run in your browser with WebAssembly CAD engines. Upload DWG or DXF and work immediately on Windows, Mac, Linux, or tablet.
Is my drawing uploaded to your servers?
By default, files parse locally in your browser. Upload only happens when you explicitly create a Share link or use cloud features.
What is the free file size limit?
Free accounts can open files up to 15MB. Starter ($8.8/mo) supports 50MB, Pro 100MB, and Team 200MB per drawing.
Which DWG versions are supported?
AutoCAD DWG R12 through 2024 and DXF (ASCII and binary). Most 2D shop drawings open cleanly.
