Drop a DXF and it opens right here — nothing is uploaded.
DXF Viewer
View a DXF drawing in your browser — pan, zoom, switch layers on and off, and save the view as a PNG for an exhibit. No AutoCAD, no sign-up, and the drawing never leaves your machine.
Good to know
- Lines, polylines, arcs, circles, ellipses, splines, text and block references are drawn; layer colours come from the file.
- Anything that could not be drawn — hatching, leaders, 3D solids — is listed by type and count rather than left out quietly.
- DWG is not DXF. Open the drawing in any CAD program and Save As DXF first; DWG is a closed format with no open reader that could ship here.
Your files stay on your machine
This tool runs entirely inside your browser tab. Nothing is uploaded, stored, or sent to a server — close the tab and every trace is gone.
These are the free ones — see the full suiteHow big a file can it take?
There is no upload, so there is no upload limit — but the work happens in this tab, which means your browser’s memory is the budget. Nothing here will refuse a file for being large; a big enough one simply gets slow and, eventually, reloads the tab. The figures below are rules of thumb on a desktop browser, not enforced caps. On a phone or tablet, expect a good deal less.
- The whole drawing is held as geometry and redrawn each frame, so entity count is what binds — comfortable to around 200,000 entities, sluggish beyond.
- Off-screen geometry is skipped while panning, so zooming in makes a heavy drawing feel lighter, not heavier.
Password-protected PDFs are declined whatever their size — unlock the file first. If a run does die on a long document, splitting it into volumes and working through them one at a time is the reliable way round it.
