For occasional conversions or when you do not want to install any software, free online converters like Zamzar and CloudConvert offer straightforward solutions. They support batch conversions and direct export to DWG/DXF formats. However, free versions typically have file size limits and daily conversion caps. They are best suited for small, non-confidential files. For raster PDFs, free online converters generally perform poorly compared to specialized desktop software.

It can handle PDFs created directly from CAD software (vector PDFs) as well as scanned drawings and maps (raster images). For scanned PDFs, it uses a raster-to-vector conversion engine to trace and recreate lines, arcs, and text.

: Unlike basic raster conversion, AutoDWG identifies lines, arcs, polylines, and circles, rebuilding them into native CAD entities.
