How do I convert X3F to JPG?

Upload your X3F file above. It is converted to JPG automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting X3F to JPG lose quality?

JPG is lossy, so some fine detail is discarded to make the file smaller. Raise the quality in Settings for a closer copy.

X3F or JPG: which should I use?

Use X3F for adjusting exposure and white balance with maximum latitude. Use JPG for photos you share, email, print or upload. Keep in mind the main drawback of JPG: no transparency, and every re-save loses a little more detail.

X3F is the RAW format of Sigma cameras with Foveon sensors, from the SD and DP series to the Quattro models. It stores the unprocessed sensor data for maximum editing latitude, so most apps can’t show it as a normal picture.
