How to Convert X3F to JPG in 3 Easy Steps
Follow these three simple steps to convert Sigma X3F photos to JPG. No software installation required. Free and secure.
Add X3F Photos
Select Sigma X3F files from your device, choose a photo folder, or drag and drop your camera files into the browser.
Convert to JPG
JPG is selected by default. Adjust the quality setting if needed, then start converting your X3F photos.
Preview and Download
Check the converted photos and JPG file sizes, then download images individually or together as a ZIP file.
How Does the X3F to JPG Converter Work?
The CompressFly X3F to JPG converter attempts to decode supported Sigma X3F files directly in your browser and creates a JPG from the image it can render. X3F files contain data from Sigma cameras with Foveon sensors, whose layered image data and processing differ from many other camera RAW formats. Compatibility can vary by camera generation, and an embedded preview may be used when the full X3F data cannot be decoded.
Compare the JPG resolution, orientation, color, tonal balance, and fine texture carefully, because a preview or general RAW decoder may not match Sigma-specific processing. Keep the X3F source for later development in compatible software. Conversion remains local for individual photos or batches, with no server upload or signup.
What "in your browser" means
- No X3F photos are uploaded to a server
- Sigma X3F files are converted locally on your device
- Completed JPG photos download directly from your browser
