About MyGeodata Converter
Files can be uploaded using multiple selections or packed into any supported format (ZIP, RAR, 7Z, TAR, GZIP). If the input format is directory-based, it is necessary to pack whole directory - not only the content.
To avoid considerable servers loads we had to set conversions limits for each user - please see Free plan. If you exceeded the limit, you may register a prepaid plan - otherwise you will be charged by credit card during the conversion process (one-off payment). Your charges allow us to cover costs associated with the servers operation and to improve our service.
