If you work with AutoCAD you have probably had a regular requirement to convert an image to an AutoCAD format. The problem is that many conversion solutions will not give you the results you require. In this post we’ll discuss how you can accurately convert your images to DXF or DWG saving you from manually tracing your designs.
Let’s begin with a demonstration of how professional conversion software, Scan2CAD, can convert an image to an AutoCAD format.

It won't take more than two minutes.
To answer that question, we should first get specific; in this post we’re focussing on converting raster images to an AutoCAD format (i.e. DXF or DWG). A raster image is an image formed of pixels such as JPG, BMP, TIF and many more file types.
Raster images are different to vector images. Vector images (such as vector PDF files) are typically much easier to convert to an AutoCAD format because DXF and DWG are also vector file types. The technical term for converting raster images to DXF/DWG is ‘raster to vector conversion’.

What are your options when converting an image to AutoCAD?
When you need to convert an image to AutoCAD you have three options:
- Convert using Raster Design
- Convert with conversion software
Option 1: Manually trace the image
If you opt to manually trace a drawing you will commit yourself to a long painstaking process of drawing over each individual element in your image. It’s surprising that many people are still manually tracing raster images when automatic conversion software could save them countless hours and therefore budget.
Some AutoCAD users may prefer to manually trace an image because they believe that it is not possible to achieve a high degree of accuracy with conversion software. This is due to the vast difference in conversion accuracy offered by the conversion software available (most notably, the poor results provided by online converters). In almost all cases, the far better option is to automatically convert your image to AutoCAD format and then manually edit the file to get that final 1% accuracy if required.
Option 2: AutoDesk’s Raster Design
Raster Design is Autodesk’s solution for automatically converting a raster image for AutoCAD.
Unfortunately Raster Design is not AutoDesk’s core product and it doesn’t offer much of the required functionality to produce useful converted images, therefore a significant amount of manual input is still required.
Raster Design utilises simplistic vectorization methods which are not designed to convert each image element to their correct vector CAD entity. Instead, all elements will be represented as lines or polylines.

Raster Design may be commonly used by AutoCAD users due to the fact that it is part of the AutoDesk product offering. Therefore there is little friction in trying Raster Design’s conversion results first before finding that better results can be achieved with another solution.
Option 3: Convert with conversion software
Using Scan2CAD to convert text and other elements in an image
Scan2CAD is raster and vector conversion software designed specifically for CAD & CAM. We have spent the last 20 years focussed purely on improving the conversion performance, saving time and money for the world’s design, manufacturing and AEC companies.
If you need to convert an image to AutoCAD format you will most likely find that Scan2CAD will offer the best performance in almost any circumstance.

Unlike Raster Design, Scan2CAD is a standalone application which doesn’t need to be ran as a plugin to other CAD software. Scan2CAD offers OCR and object recognition which means you will convert image entities (including text) to the correct vector CAD data.
Why do some converters create poor quality results?
Scan2CAD converts a circle to a vector circle entity, not a collection of lines
The worst type of image conversion would be to convert every object in your image to the same vector element. For example some vectorization software might convert a circle in an image to thousands of small vector lines or polylines instead of a single CAD circle entity.
With this type of simplified vectorization software; the text, arcs, circles and all other elements would be represented as many individual connected vector lines. But that is practically useless if you need to edit the CAD drawing in AutoCAD.
This is why you need conversion software which has object recognition capabilities. What is object recognition? It is the process of identifying entities (objects) in your raster image and converting them to the correct vector CAD entity.
What if the image contains text?
If your drawing contains text you will need to ensure that your conversion software has OCR capabilities. OCR (optical character recognition) converts text in your image to editable vector text strings, identical to the text strings you would create when writing text in AutoCAD.
If your conversion software does not have an OCR feature, the software will instead convert all the text in your image to a collection of vector lines or polylines. We call this ‘exploded text’ but it is not really text at-all, it is simply vectors in the shape of text.

The ‘exploded text’ can not be edited in CAD software so you will need to erase these vectors and redraw the text in AutoCAD.
Conclusion – How to convert an image to AutoCAD
If you need to convert an image for AutoCAD we recommend that you choose software designed specifically for that purpose.
Scan2CAD offers the most accurate conversions of your raster and vector designs. With automatic conversion software you will save countless hours spent fixing poor quality conversions or manually tracing files.

Description | JPG – is a popular graphic format, which is characterized by a high image compression rate, which leads to a decrease in image quality. It uses the technology of encoding of smooth color renditions, providing the ability to reduce the amount of data frequently during the recording of the image. Because of the small size it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPG algorithm is optimally suitable for compressing photographs and pictures, in which realistic scenes with little contrast of colors are present. It is not recommended to use this format for compression of drawings and various kinds of graphics, since a strong contrast between a number of closely located pixels provokes the appearance of visible artifacts. |
Technical details | The procedure for compressing the digital images in JPG format is carried out in several stages. First, the photo is transformed into a color space YCbCr, then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a 'lossy' compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial. |

Description | DWG are binary file formats used in the storage of two and three dimensional images mainly used by devices that use computers in design development. The initial development of the file format was in the 1970s and is currently used by professionals like architects, engineers and designers. Licensing for the AutoCAD application is by Autodesk who ownы the application and it is commonly used as the standard for most CAD drawings. Auto desk has been resistant to people determine their source code and have placed watermarks on the different released versions. |
Technical details | Files in the DWG format possess vector image data and metadata which mainly using binary coding. A display of the DWG is executed based on instructions that came from data related to an image. Files created by AutoCAD are verified for the purpose of increasing validation of the files. Software like the Autodesk DWG Trueview allows free usage but lacks the TrueConvert software. The free software allows users to view files while utilizing features like the measure and mark up, organization of sheet set and allows them to track their progress. For software like DraftSight, DWG files can be created, edited and viewed. LibreDWG is working to develop free software libraries for files in the DWG format due to the absence of open source viewers for this format. |
