How do I convert JP2 to PEF using LetsConvert?

Upload your JP2 file from your device or cloud storage, select PEF as the output format, and click 'Convert'. The file will be processed, and you can download the resulting PEF file. For multiple files, use the batch upload option to convert up to 20 files at once.

Why would I want to convert JP2 to PEF?

JP2 (JPEG 2000) is a highly compressed format often used for archival, while PEF is the raw image format from Pentax cameras. Converting to PEF allows you to edit the image in Pentax's Digital Camera Utility or other raw editors that recognize PEF but not JP2. This workflow is useful when you need to apply advanced lens corrections or adjust white balance without chroma subsampling artifacts.

What happens to image data when converting JP2 to PEF?

PEF stores the image data in a lossless container, so no additional compression is applied. However, if your JP2 was created with lossy compression, the original detail is permanently lost and cannot be recovered. The conversion preserves resolution, ICC color profiles, and EXIF metadata, but transparency (alpha channel) is flattened because PEF doesn't support it.
