DXF to PDF converter

Turn a DXF into a print-ready PDF sheet — black on white, real lineweights, the way a CAD drawing is meant to plot. Free, in your browser, no account with no account. DWG input works too.

Output: PDF — print-ready sheet

Checking converter…

5 free conversions a day, no account needed. Create a free account for more and files up to 30 MB.

Need a different output? The full converter writes DXF, PNG and SVG from the same drawing — or go straight to DWG to SVG.

Just want to read the drawing? The free browser viewer parses DXF entirely on your own machine — nothing is uploaded.

3 steps

From DXF to a sheet you can send

Drop the DXF in

Drag your .dxf onto the converter above, or click to browse for it. DWG files work here too.

It plots, not screenshots

The drawing is plotted to a landscape sheet at 300 DPI — black geometry on white, with the drawing’s own lineweights.

Download and send it

You get a PDF anyone can open, print or mark up — no CAD software required at the other end.

Why the output looks right

A plot, not a screenshot

Most free "DXF to PDF" tools render the drawing the way it looks on screen — yellow and cyan lines on a black field — and the result is unreadable on paper and unusable in a submittal. CADdillo plots the way a CAD program plots.

Who this is for

Sending a drawing to someone without CAD

A DXF is a drafting file. A PDF is a document. When the person on the other end is a client, a contractor, a plan reviewer, a fabricator’s front office or an inspector, they do not want to install anything — they want to open the file, read it, print it and mark it up. That is what PDF is for.

If they need to edit it rather than read it, send the DXF itself, or convert a DWG to DXF first so they can open it in whatever CAD program they own.

Answers

DXF to PDF, answered

How do I convert a DXF to PDF for free?

Drop your .dxf file on the converter above and download the PDF. Output is already set to PDF, so there is nothing to configure. It runs in the browser with no software to install and no account — five files a day free, and it accepts DWG input as well as DXF.

Do I need AutoCAD to convert DXF to PDF?

No. AutoCAD costs roughly $2,030 a year and AutoCAD LT about $500, and neither is necessary just to turn a drawing into a shareable PDF. If you draft full-time, LT is a more complete tool and we say so plainly on our comparison page — but for converting a file someone emailed you, this is free and takes about fifteen seconds.

Will the PDF print like a real CAD sheet?

Yes. The plot follows CAD plotting convention rather than screen convention: black geometry on a white background, with the drawing’s own lineweights honored, rendered at 300 DPI. It is a plot, not a screenshot of a dark CAD window, so it reads correctly on paper and in a submittal.

Does the whole drawing fit on the page, or does it get cropped?

The full extents of model space are plotted to a single landscape sheet — nothing is silently cropped. For a very large plan that means fine detail is dense at letter size; printing to 11x17 or larger handles it better, and converting to SVG instead gives you infinite zoom with no pagination at all.

Is there a file size limit, and do I need an account?

Five conversions a day are free with no account, up to 10 MB, behind a quick bot check. A free account (no card required) removes the daily limit and raises the file cap to 30 MB. The converter is free permanently — it is not a trial.

What happens to my DXF after I convert it?

The conversion runs server-side, and the uploaded file plus its converted PDF are deleted immediately after the response is returned — they are transient artifacts, never stored. If you only need to read a DXF rather than send it, the in-browser viewer parses it entirely on your own machine with no upload at all.

Why does a large DXF take longer to convert?

Plotting to PDF renders every entity in the drawing, so the time scales with drawing complexity rather than file size alone. A small detail sheet is nearly instant; a 60,000-entity facility plan takes up to about a minute. That is real rendering work, not a queue.

Can I convert several DXF files to PDF at once?

Not yet — conversion is one file at a time. Batch conversion is a planned feature; if it would be useful to you, say so on the contact page, because that is how features get prioritized here.
