How do I convert PEF files to JXL with LetsConvert?

Upload your Pentax PEF file, choose JXL as the output format, select lossless or lossy compression depending on your needs, and click Convert. After processing, download your converted JXL file. The tool runs entirely in your browser and preserves EXIF metadata automatically.

Why should I convert PEF to JXL instead of keeping the raw file?

PEF files are large raw images designed for editing. JXL (JPEG XL) offers superior compression and lossless encoding, so you can archive final images in a fraction of the size without losing quality. JXL also supports HDR and wide color gamuts, making it a future-proof format for sharing or printing.

What happens to color profiles and metadata during PEF to JXL conversion?

Our converter preserves the embedded ICC color profile (like Adobe RGB or sRGB), EXIF data, and high bit depth when converting to JXL. Since JXL supports lossless compression, all image data can be retained. However, camera raw adjustments such as white balance and tone curves become baked into the final image, as JXL is not a raw format.
