Before you write: two things that are working as intended
“It says my PDF is a scanned or image-based drawing.” That check is deliberate. A scan is a picture of a drawing — there is no vector line work in it to convert. Tracing a picture produces closed outlines with no snappable lines, arcs or layers, which is not usable for engineering work, so this tool does not pretend to do it. What to do instead: ask whoever produced the drawing for the original CAD file, or for a PDF exported from CAD rather than scanned. If you genuinely need a scan vectorised, a dedicated raster-to-CAD tool is the right kind of product for that job.
“The DXF has no layers.”
Layer names only survive if the PDF carries them. Many CAD exports do not include layer
information — AutoCAD and MicroStation leave that box unticked by default. When the
information is not in the file, everything lands on layer 0, and the extension says so on
the result screen. If you can, ask for the PDF to be re-exported with
“Include layer information” ticked.
If a drawing really will not convert
Send us:
- The PDF, if you are allowed to share it — many drawings are confidential, and we do not need it to be. If you cannot share it, send the rest and we will work from that.
- The message you saw, including the small grey line of detail underneath it (it reports what the extension actually measured on that page).
- Which page of the document you were converting.
- What you expected — for example “this sheet has 20 layers in AutoCAD but the DXF has one”.
That fourth one matters more than it looks: most reports we can act on are of the form “the file opened, but this specific thing is wrong”, and the specific thing is what points at the cause.
Which CAD programs the DXF opens in
The file is written as DXF R2007 (AC1021), which is the version most programs accept without a converter. We have opened the output in QCAD on every drawing we test — 11 files, no failures — and read it back with ezdxf, an independent Python library, on all of them.
That is what we have actually verified, so that is what we claim. AutoCAD, LibreCAD, Fusion, Rhino and BricsCAD all read DXF of this vintage, but we have not personally opened our output in each of them; if yours refuses the file, that is a bug worth reporting and we will want the file and the program version.
If your workflow needs DWG, open the DXF in your CAD program and save as DWG — that conversion is one step and lossless in practice. This extension does not write DWG itself.
Does a failed conversion use up one of the free three?
No. The counter goes down only once the DXF exists and is on your screen — a refused scan, a file that is not a PDF, or a conversion that errors out costs you nothing. If you convert but then close the tab without saving, that one does count: the work was done and the file was yours to save.
How fast we answer
One person reads that inbox, in European hours. Most replies go out within a working day. If you have not heard back in three, send the message again — it went astray, and we would rather be nagged than silently miss it.
Refunds
The paid version is a single payment, not a subscription. If it does not do what this site says it does, write to us and we will refund it.
Privacy
See the privacy policy. The short version: your drawings are converted inside your browser and are never uploaded.
