One Nikon D60 RAW file converted to five formats, at quality 90 where the format has a quality setting. PNG is lossless, so it is the largest. Seconds are the median of three runs. Measured with the Contenta Converter 9.0.35 command line on an AMD Ryzen 9 3900X, 2026-09-30.

IFF (Interchange File Format) is the 1985 Amiga image format developed by Electronic Arts for Commodore. Its ILBM (interleaved bitmap) variant was the native format for Deluxe Paint and became the de facto standard for Amiga graphics through the 1990s. Files can store HAM (Hold-and-Modify) mode images, brushes, palettes, and animation chunks.

Optimize file size, keep important metadata, and prepare images for web, print, or long-term archiving in just a few clicks.

Description IFF (Interchange File Format) is the 1985 Amiga image format developed by Electronic Arts for Commodore. Its ILBM (interleaved bitmap) variant was the native format for Deluxe Paint and became the de facto standard for Amiga graphics through the 1990s. Files can store HAM (Hold-and-Modify) mode images, brushes, palettes, and animation chunks.
Benefits Chunked container design predates and inspired modern formats — IFF's idea was borrowed into AIFF (Apple audio) and RIFF (Microsoft multimedia). Supports HAM6/HAM8 modes that let Amiga hardware display 4,096 colors from a 32-color palette, which was the killer feature for 1980s art.
Drawbacks Amiga-era only. Modern viewers rarely open IFF directly, and you lose all the HAM and palette tricks when converting to a standard format like PNG — the pixel data maps, but the Amiga hardware chroma effects were never part of the file. Useful today mostly for retro collectors and digital archivists.
