How do I convert a PNG file to X3F format?

Use the upload button to select your PNG, choose X3F as the target format, optionally set the bit depth or color space, and click Convert. The tool processes the file and provides a direct download link for the X3F file.

Why would I convert PNG to X3F instead of keeping it as PNG?

PNG is a lossless raster format for web and graphics, while X3F is Sigma's raw sensor format with high dynamic range. Converting PNG to X3F allows you to work with the image in Sigma Photo Pro and other raw editors that support X3F, enabling advanced color grading and detail recovery.

Does the PNG to X3F conversion preserve transparency and color profiles?

The converter preserves RGB color data and bit depth from the PNG, but X3F does not support alpha channels, so transparency is flattened (usually to white or black). Color profiles are embedded where possible, and the image is stored using X3F's compression algorithm. Resolution and DPI remain unchanged.
