What is a .orf file?

File extension details and usage information

The ORF file extension represents the raw image format used by Olympus digital cameras. Raw image formats, unlike JPEGs, contain minimally processed data directly from the camera's sensor. This means that the ORF file retains a much wider dynamic range and color gamut than a JPEG, allowing for greater flexibility in post-processing. The ORF file stores all the information captured by the camera's sensor, including metadata such as camera settings, date, and time. This makes it ideal for photographers who want maximum control over the final image. Because it's unprocessed, an ORF file typically requires specialized software to view and edit. The advantage of using ORF is the ability to make significant adjustments to exposure, white balance, and other parameters without degrading the image quality, which is a common issue with JPEG files. The file size is also significantly larger than a JPEG due to the amount of data stored.

To open a .orf file, use software that supports this file format.

  • Olympus Workspace
  • Adobe Photoshop
  • Adobe Lightroom
  • Capture One

Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.

  1. Verify that the file extension is correct.
  2. Install or update compatible software.
  3. Try another application that supports this format.
  4. Check whether the file is corrupted, incomplete, or encrypted.

A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.

File safety tips

Use caution with unknown files

Only open files from trusted sources. Before opening a .orf file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
