When I switched from Mac to Windows, I couldn't open my old DWG files. reaConverter saved me – it converted them all to PDF and JPG with perfect scaling. Now I can view my CAD portfolio on any device. Thank you for making cross‑platform work possible!

After nearly two years of relying on online converters, I finally installed standalone software. Why didn't I do this sooner? Now I can work completely offline — no more wasted time uploading/downloading or eating through my data allowance!

FAQ

ISS to DWG Conversion

What are ISS files?

The ISS image format is considered rare and obsolete, and such files can only be opened using a limited number of image viewers. ISS files most likely contain bitmap images that were created or edited a long time ago. In case you have received such a file or found one on an old hard-drive, the best way to access its content is conversion to a better known format, such as JPEG or PNG.

What are DWG files?

DWG (which stands for "Drawing") is a proprietary format of AutoCAD, a program widely used for creating engineering and architectural projects. The format is also a default extension used by several other computer-aided design (CAD) pieces of software, including IntelliCAD, Caddie or DraftSight.
