Convert PSD to IFF

Understanding PSD and IFF file formats

PSD (Photoshop Document) is Adobe Photoshop's native file format, supporting layers, masks, transparency, and a wide range of color modes. It is widely used for complex image editing and graphic design projects.

IFF (Interchange File Format) is a generic container file format originally developed by Electronic Arts and Commodore. It is commonly used for storing images, audio, and other data, especially on Amiga computers. The most popular IFF subformat for images is ILBM (InterLeaved BitMap).

Why convert PSD to IFF?

Converting a PSD file to IFF is often necessary when transferring graphics from modern design tools to legacy systems, such as the Amiga, or for use in retro computing projects. IFF is also used in some multimedia and game development workflows.

How to convert PSD to IFF

Direct conversion from PSD to IFF is not widely supported by mainstream software. The process typically involves exporting the PSD to a more common format (such as PNG or BMP) and then converting that file to IFF.

Recommended software for PSD to IFF conversion

• XnConvert: A free, cross-platform batch image converter that supports exporting to IFF (ILBM). First, flatten and save your PSD as a PNG or BMP, then use XnConvert to convert it to IFF.
• IrfanView (Windows): Supports IFF export with the appropriate plugins. Open your PNG/BMP and use File → Save As to select IFF.
• GIMP: Open the PSD, export as PNG or BMP, then use a dedicated IFF converter for the final step.
• Online converters: Some online tools (e.g., Convertio) may support direct PSD to IFF conversion, but results can vary.

Step-by-step conversion process

1. Open your PSD file in Photoshop or GIMP.
2. Flatten the image if it contains layers.
3. Export the file as PNG or BMP using File → Export → Export As or File → Save As.
4. Open the exported file in XnConvert or IrfanView.
5. Convert and save the file as IFF (ILBM) using File → Save As and selecting the IFF format.

Tips for best results

• Ensure your image uses a color depth compatible with IFF (often 8-bit or less).
• Check the IFF file on your target system to confirm compatibility.
• For batch conversions, XnConvert is highly recommended.
