Extract text from Raster image overviews (OVR)
To convert OVR Overviews to another format, you need GDAL or other GIS software.
To convert other file formats to the "Raster Image Pyramid" file type, you need software like GDAL or a similar tool.
The .OVR file format primarily functions as a Raster Image Overview generated by the Geospatial Data Abstraction Library (GDAL). These files store multi-resolution pyramid layers - pre-calculated, lower-resolution versions of a massive base image. They sit alongside large geospatial datasets, such as TIF or IMG files, allowing GIS applications like QGIS or ArcGIS to render and pan across complex maps rapidly without loading gigabytes of raw data into memory.
Despite their utility in mapping, .OVR files present significant handling challenges for average users. They are strictly dependent sidecar files; an .OVR file is useless if separated from its parent raster image. You cannot open an .OVR file in standard web browsers, and traditional image viewers will fail to recognize the format. Furthermore, they consume additional disk space, sometimes inflating the total dataset footprint by 30% or more. Sharing an .OVR file with a client or colleague who lacks specialized geospatial software is a guaranteed dead end.
To make this visual data accessible to non-technical audiences, conversion of the parent dataset is necessary. For web publishing, convert the underlying map to WebP or PNG to guarantee browser compatibility. For reports or client reviews, exporting to a georeferenced PDF or standard JPG is best, though you will lose dynamic rendering and embedded spatial metadata.
Convert.Guru analyzes your OVR file, detects the exact format, and lets you read the text inside.
Users also converted TFW, JP2, TIF, PNG, SVG, XML, IDX, JPG, ZIP, SPV, PDF, DAT and PKPASS files.
If you want to convert OVR file to TIFF, SVG, AI, EPS, PDF, JPG, CDR, WMF, EMF, SWF, FLA or XFL, you can use GDAL or similar software from the "Geospatial Raster Image Overview" category. In the File menu, look for Save As… or Export….
To convert AFPUB, EPS, FIG, VSD, SKETCH, VDX, AFPHOTO, PDF, AFDESIGN, SVG, VSDX or AI files to OVR, try GDAL or another comparable tool in the "Geospatial Raster Image Overview" category.
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 OVR converter.
