Convert DWG to PDF Online
Open a DWG or DXF drawing in your browser and export it to PDF in two clicks. Nothing is uploaded: the file is read locally with FileReader, DWG is parsed by LibreDWG compiled to WebAssembly, and the PDF is assembled on your own machine. No account, no signup, no watermark, no usage limit.
Read this first: the PDF is a raster snapshot, not a vector plot
The export takes a JPEG image of exactly what is on screen and places it on a single A4 landscape page. It is not a vector plot. In practice that means three things: text in the PDF is not selectable or searchable, lines soften once you zoom past the captured resolution, and the sheet has no plot scale. That decides whether this tool suits your job. If you need a crisp, scaled, vector PDF for issue or archive, skip to the alternatives below — desktop CAD is the correct tool and we would rather say so than waste your time.
How to convert DWG or DXF to PDF, step by step
- Open the viewer and load the drawing — go to the DWG viewer or the DXF viewer, then drag the file onto the window or use Browse Files. DWG files from AutoCAD R14 through 2026 are supported (AC1014 through AC1032); ASCII DXF is read by a dedicated parser.
- Hide the layers you do not need — switch off anything that should not appear on the sheet: construction lines, hatching, furniture, survey noise. Each layer shows its entity count, so the layer carrying the clutter is easy to spot. Anything hidden here is absent from the PDF.
- Frame the view — use the top, front and right presets to square the drawing up, switch to orthographic for a plan without perspective convergence, then zoom and pan until the area you care about fills the window. Framing tightly is the single biggest lever you have over output quality.
- Add markup if the PDF is for review — arrows, rectangles, circles, freehand and text annotations are captured along with the drawing, as are measurement labels and any active clipping plane. Mark up before you export, not after.
- Export — press Ctrl+Shift+E or click the PDF button in the toolbar. The page is generated on the spot and downloads to your device: no queue, no email step, no server round trip.
Controlling the output: what you see is what you get
There is no page-setup dialog, and that is deliberate — because the export captures the viewport, your zoom level and your layer visibility are the export settings. Change the screen, change the PDF. Four things carry straight into the file.
Zoom sets the effective resolution
The snapshot has a fixed pixel budget, so a whole floor plan squeezed into the window spends very few pixels per room. Zoom in and the same budget covers a smaller area — which is why a detail exports far more legibly than a full sheet.
Layer visibility sets the content
Whatever is hidden in the layer panel does not exist as far as the export is concerned. Turning layers off is how you get a clean single-discipline sheet out of a busy composite drawing.
View and render mode set the look
Top, front and right presets plus the orthographic and perspective toggle decide orientation. Solid, wireframe and x-ray modes are captured as shown, so an x-ray view exports as an x-ray view.
Window size and theme matter
A maximised browser window gives a larger capture than a narrow one. Light theme puts dark linework on white, which is what you want on paper; dark theme exports dark and reads poorly in print.
Raster PDF versus vector PDF, in plain terms
Both are files ending in .pdf, and that shared extension hides a fundamental difference in what is stored inside.
A vector PDF stores geometry
Lines, arcs and text are recorded as coordinates and characters, so edges stay razor sharp at any magnification because the reader redraws them. Text can be selected and searched. Lineweights, plot styles and a defined plot scale survive, so a PDF measuring tool returns real dimensions. This is what a CAD plot produces.
A raster PDF stores pixels
The drawing is flattened into a grid of coloured dots before it reaches the page. Zoom in and you eventually see the grid, because no geometry is left to redraw — only the picture that was taken. Text is part of that picture, so nothing can be selected, searched or measured.
Neither is better in the abstract. A raster page is a faithful record of a view; a vector page is a faithful record of a drawing. The mistake is using one where the other is required.
When a raster PDF is perfectly fine
- Sharing a view with a colleague, client or contractor who needs to see what you are talking about.
- Emailing one detail instead of a 40 MB file the recipient cannot open anyway.
- Marking up a query with arrows and text, then sending it back to the author.
- Embedding a drawing view into a report, inspection record, meeting minutes, RFI or slide deck.
- Getting something readable onto paper quickly, for a reader who will look rather than measure.
When it is not enough
- Printing to a scale such as 1:50 or 1:100, or anything scaled off with a rule.
- Issuing drawings for construction, tender, approval or archival records.
- Passing geometry on for further CAD work — send the DWG or DXF itself.
- Large-format plotting to A1 or A0, where a screen-resolution image falls apart.
- Anything needing selectable text, searchable annotation or measurement inside the PDF.
If you need a true vector PDF, use one of these instead
This viewer cannot produce vector output, so here is the honest routing. Desktop CAD applications — AutoCAD, BricsCAD, DraftSight and, for DXF work, LibreCAD — plot to PDF from their own plot dialog, where you set sheet size, plot scale, plot style table and pen assignments. That path keeps lineweights, keeps text as text and keeps the drawing measurable. Autodesk also publishes DWG TrueView, a free viewer that plots DWG to PDF without a full AutoCAD licence.
Failing that, any application that can open and print the drawing can send it to a print-to-PDF driver — Microsoft Print to PDF on Windows, or the PDF option in the macOS print dialog. Printing through a driver from a CAD application still gives vector output and a real page setup, which is the part that matters. Both routes run on your own machine, exactly like this viewer.
What renders, and what does not
The PDF can only contain what the viewer managed to draw, so know the gaps first. External references (xrefs) are not resolved, so anything in an attached drawing is missing. Proxy and custom objects from applications such as Civil 3D or Advance Steel do not render. Custom SHX fonts are substituted, which can change text width and spacing. Complex hatch patterns appear as boundary outlines only. DIMENSION entities in DWG files may not render at all. Check the screen against what you expect before exporting — what is missing on screen will be missing on the page. And worth restating: this is a viewer, so you cannot edit geometry or save back to DWG.
DXF to PDF, and other formats
Converting DXF to PDF is the identical procedure: load the ASCII DXF, hide layers, frame the view, press Ctrl+Shift+E. The same export works for STL, OBJ, 3DS, glTF, GLB and FBX models. If you would rather have a plain image, the PNG export gives the same capture without the A4 wrapper.
Try it on a sample drawing first
These open instantly in the viewer, so you can run an export and judge the output quality on real geometry before committing your own file.
Frequently asked questions
Is the exported PDF vector or an image?
It is an image. The export places a JPEG snapshot of the viewport on a single A4 landscape page. There is no vector geometry and no text layer, so text cannot be selected or searched and geometry cannot be measured in a PDF tool. For vector output, plot from desktop CAD software or through a print-to-PDF driver.
Can I print the PDF to scale?
No. The export captures whatever is on screen at whatever zoom you are using, so there is no plot scale such as 1:50 or 1:100 and nothing in the PDF can be scaled off reliably. Use it to communicate a view, not to issue a drawing someone will measure. Scaled plotting needs CAD software with a plot dialog.
Why is the text in my PDF blurry?
Because the page holds a picture of the text rather than the text itself. The snapshot is captured at viewport resolution, so anything only a few pixels tall, such as small annotation or a dense title block, softens as soon as you zoom in. Zoom into the area you care about before exporting, maximise the browser window, and hide unneeded layers — that gives the text more pixels and a sharper result.
Can I convert DXF to PDF as well?
Yes. The steps are identical for ASCII DXF files, and the same export also works for STL, OBJ, 3DS, glTF, GLB and FBX models. Load the file, frame the view, press Ctrl+Shift+E. The result is the same raster A4 landscape page.
Is my drawing uploaded to a server during conversion?
No. The file is read in the browser with FileReader, DWG is parsed by LibreDWG compiled to WebAssembly, and the PDF is assembled on your own device. Nothing is transmitted, there is no account or signup, and there is no watermark or usage limit. Installed as a PWA, the viewer works offline.
What paper size is the PDF, and can I change it?
Every export is a single A4 landscape page with the captured view placed on it. Page size, orientation and margins are not adjustable and multi-sheet output is not supported, so one export produces one page. For a specific sheet size such as A1 or ARCH D, plot from desktop CAD instead.
