  2. 02

    Adjust the photo

    Click Auto, move the style slider, then fine-tune the resulting values.

  3. 03

    Save a new file

    Choose JPG or PNG in Output settings, export, and download the result.

Compatibility and fallback

Full RAW decoding depends on the camera encoding, browser, available memory, and image size. If decoding fails, a usable embedded JPEG may be offered and labeled; it is not full RAW decoding. A file without either source cannot be exported.

This Merrill X3F is decoded from Foveon sensor data with LibRaw X3F tools. The smaller preview preserves the measured full-size export dimensions.

Answers before you start.

What is a X3F file?
X3F is a camera RAW format used by Sigma. JPG is easier to share; keep the RAW original for future edits.
How do I convert X3F to JPG?
Choose the file in the editor, use Auto or adjust the sliders, then select JPG in Output settings and export. PNG is also available.
Can I edit before converting?
Yes. Auto color, exposure, contrast, highlights, shadows, saturation, Looks, and crop can be adjusted before export.
Are my RAW photos uploaded?
No. Preview, color adjustment, and export run on your device. The editor writes a new output file and leaves the original unchanged.
