How do I convert X3F files to HEIC using LetsConvert?

1. Upload your X3F file from Sigma or Foveon camera. 2. Select HEIC as the output format. 3. Adjust settings like quality and resolution if desired. 4. Click 'Convert' and download the resulting HEIC file. The process is fully automatic and preserves your original EXIF data.

Why should I convert X3F to HEIC instead of keeping raw files?

X3F raw files are large and require specialized software like Sigma Photo Pro. HEIC (HEIF) uses advanced HEVC compression, making images up to 80% smaller while retaining visual quality. HEIC is natively supported by Apple devices, making it ideal for sharing, cloud storage, and editing in iOS/macOS. It also preserves metadata like EXIF and color profiles.

What happens to X3F sensor data, color profiles, and EXIF when converted to HEIC?

During conversion, the raw sensor data is processed through a demosaicing algorithm to create a standard image. The converter preserves the color profile (such as Adobe RGB or ProPhoto RGB) and EXIF metadata. However, the original raw sensor information is lost because HEIC is a final image format, not a raw format. You can adjust white balance and exposure during conversion to optimize the output. The HEIC file is saved in 10-bit depth if supported, retaining high dynamic range.
