How do I convert X3F files to JXL?

Upload your X3F files (from Sigma SD or DP cameras) using the upload button. Select JXL output format, then choose either 'lossless' for exact reproduction or 'lossy' with a quality slider for smaller files. Click Convert, and after a few seconds, download your JXL files. Batch conversion is supported.

Why should I convert X3F to JXL?

X3F is Sigma's raw format, capturing unprocessed sensor data with huge file sizes (up to 100 MB per shot). JXL offers comparable visual fidelity at a fraction of the size, and is supported by modern browsers and photo editors like Photoshop, GIMP, and Affinity Photo. Converting preserves your ability to share or archive images without losing quality.

What happens to color profiles and metadata when converting X3F to JXL?

The converter decodes the X3F sensor data, applies the embedded color profile (e.g., sRGB or Adobe RGB), and preserves the original resolution and 16-bit depth. EXIF metadata (camera, lens, exposure) is retained. JXL also supports lossless compression, so there is no quality loss in the conversion step. However, if the original X3F has no transparency layer (since it's raw), the output JXL will be opaque.
