About Swage

Who makes it

Swage is made by engineers who spent years moving data between CAD and GIS and know where it breaks along the way. So we tell you up front what a format will lose, and we check the result ourselves before it reaches you.

What it is for

Swage converts geodata from one format to another. You upload a drawing or a GIS file and pick a format. Before anything is written, you see what will change. Then we read the new file back and compare it with the source file.

What we promise

• If a format is going to lose something, you'll know what and on how many features before anything is written.
• We open the finished file again and compare it with the source file.
• You can download the result for 24 hours. Within the next hour we delete the files.
