Sometimes, software just can’t figure it out. If the JPG is grainy, hand-drawn, or contains messy cross-hatching, automatic converters might create thousands of jagged, unusable lines.
Best for: Low-quality images, hand-sketches, or complex historical documents.
How to do it:
For a reliable DWG file from a JPG:
Use Scan2CAD (industry leader) or Aide CAD Converter
Export as DWG (not DXF if possible — DWG retains more entity properties)
Open in AutoCAD
Trace critical geometry again if precision required (tolerance > 0.1mm impossible from JPG).
Examples: Convertio, Zamzar, OnlineConvert, CloudConvert

Dedicated applications installed on your local machine designed specifically for raster-to-vector conversion.
Unlike a standard image converter (which changes a photo from a JPG to a PNG), a JPG to DWG converter uses a process called vectorization.
The converter scans your image, identifies the edges and shapes, and recreates them as precise lines, arcs, and circles. When you open the resulting file in AutoCAD, you aren't looking at a picture—you are looking at actual CAD geometry. Sometimes, software just can’t figure it out
