Detailed compatibility guide (Korean)

Free basic viewing

Open up to three files per day in the same browser without signing in. The count resets at midnight Korea time. Files are processed on your device. File, geometry and memory limits apply to both Free and Pro.

Pro advanced tools

Advanced tools such as search, personal review, measurement and comparison depend on the file format and require Pro. Pro removes the daily file-open limit. Payment does not guarantee file compatibility or accuracy.

File guides are available in your selected language. Workspace controls are currently in Korean.
