Convert JGW to another file type
To convert JGW world files to another format, you need ArcGIS Pro or other GIS software.
Convert a file to JGW
To convert other file formats to the "Geospatial World File" file type, you need software like ArcGIS Pro or a similar tool.
About JGW files
A .JGW file is a plain text World File used by Geographic Information Systems (GIS) to georeference a corresponding .JPG image. It contains exactly six lines of decimal numbers that define the pixel size, rotation, and geographic coordinates of the top-left pixel. Software like ArcGIS, QGIS, and Global Mapper read this file to place aerial photographs or scanned maps accurately on the Earth's surface. However, .JGW files have major disadvantages. They are sidecar files, meaning they must be kept in the exact same folder with the exact same name as the image file. If they are separated, the georeferencing is permanently lost. Furthermore, a .JGW file does not store the map projection or Coordinate Reference System (CRS). To know the projection, you usually need an additional .PRJ or .AUX.XML file. To fix these fragmented data issues, users convert them. The best approach is to combine the .JPG and .JGW into a single GeoTIFF (.TIF) file for professional archiving, or a .KMZ file for easy viewing in Google Earth.
Convert.Guru analyzes your JGW file, detects the exact format, and lets you read the text inside.
If you want to convert JGW file to JPG, SHP, KML, KMZ, GPX, GEOJSON, TOPOJSON, TIF, TIFF, ECW, SID or IMG, you can use ArcGIS Pro or similar software from the "Raster Image Georeferencing" category. In the File menu, look for Save As… or Export….
To convert LAZ, KMZ, DTM, CSV, DEM, PRJ, LAS, GPX, DSM, SHP, DBF or KML files to JGW, try ArcGIS Pro or another comparable tool in the "Raster Image Georeferencing" category.
The JGW Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our JGW converter.
