Convert DXF technical drawings to PDF — with layers, exact or fit-to-page scale, paper size and orientation, and automatic tiling across multiple sheets.
Supports DXF files (Autodesk's open interchange format), including lines, arcs, circles, ellipses, polylines, splines, text, blocks/references and dimensions. The DWG format is binary and closed — it can't be read directly in the browser; convert it to DXF first with the free ODA File Converter or with "Save as…" in your CAD program. Complex hatch patterns inside filled areas are drawn as outlines only, without the patterned fill.
Choose the technical drawing you want to turn into a PDF to share with people who don't have the original CAD software.
The drawing's visible content is recreated in PDF format, preserving the scale and line layout.
You get a file that anyone can open, view and print without specialized CAD software.
No — that's the main advantage: the resulting PDF opens in any standard PDF reader, with no need for specialized CAD software.
Yes, the conversion aims to keep the scale and proportions of the original drawing, which matters for technical drawings where measurements need to be reliable.
No — the PDF is a faithful visual representation of the drawing, designed for viewing, sharing and printing, not for further editing like a native CAD file.
No. All processing happens inside your own browser — the file never leaves your computer or passes through any external server. You can confirm this by disconnecting from the internet once the page has loaded: the tool keeps working normally.
No. PDFsy doesn't ask for sign-up, an account or payment — just open the page and use the tool.
