How do I convert an AVIF image to X3F format?

Upload your AVIF file to LetsConvert, choose X3F as the output format, and click Convert. The service processes the file while preserving embedded metadata, then provides a download link for the X3F file. You can then open it in Sigma Photo Pro or compatible raw editors.

Why would you convert AVIF to X3F?

AVIF is a highly compressed format for web display, while X3F is Sigma's raw sensor format. Converting to X3F is useful when you need to import an image into Sigma's raw workflow, apply Foveon-specific adjustments, or batch-process files in software that expects X3F input. Note that X3F cannot recover data lost in AVIF compression, but it allows using your existing raw editing pipeline.

What file attributes are preserved during AVIF to X3F conversion?

Our conversion extracts the color profile, EXIF metadata, and resolution from the AVIF file and packages them into an X3F container. Since AVIF uses lossy compression, pixel-level sensor data cannot be recreated; however, the X3F file retains the visible image data and metadata, making it suitable for editing. Transparency is not supported in X3F, so any alpha channel is merged with the background during conversion.
