What is MNG?

Multiple-Image Network Graphics (MNG) is an animation format based on PNG compression, supporting complex frame-based and sprite animations.

What is IIQ?

Phase One IIQ is a professional medium-format raw format used by Phase One digital backs, delivering exceptional image quality for commercial photography.

When Should You Use MNG vs IIQ?

MNG vs IIQ: Key Differences

• •The core technical difference: MNG relies on lossless compression whereas IIQ uses lossless compression.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •How transparency is handled: IIQ supports transparency, so alpha information is preserved during conversion.
• •File sizes: MNG files typically range Larger than animated GIF and IIQ files 50-150MB per image from medium-format backs.
• •MNG is optimized for legacy web animation, png-based video clips while IIQ is designed for professional studio photography, digital back capture — choose based on your specific workflow needs

Advantages of MNG

• ✓MNG applies lossless compression specifically calibrated for Legacy web animation, PNG-based video clips.
• ✓MNG enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓MNG guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find MNG support built into virtually every tool that handles Legacy web animation, PNG-based video clips — no plugins or converters needed.

Advantages of IIQ

• ✓The lossless nature of IIQ means file sizes stay reasonable while handling Professional studio photography, digital back capture efficiently.
• ✓From mobile devices to enterprise servers, IIQ is recognized and supported everywhere.
• ✓The trade-off for IIQ's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓IIQ is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Common Use Cases for MNG to IIQ Conversion

• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations
• Mobile app UI assets
• Product photography for marketplaces
• Digital art portfolios

Industry Applications

Best Practices for MNG to IIQ Conversion

• →Before converting MNG to IIQ, decide whether you need maximum quality or smallest file size — this determines which format truly fits
• →Save a master copy in a lossless format before converting to IIQ — you cannot recover detail lost during lossy compression
• →Check the color profile: MNG images may use a wider gamut than IIQ supports, causing a visible shift after conversion
• →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
• →Run a single test conversion first to verify quality meets your standards
• →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting MNG to IIQ Conversion

• !Converting MNG to IIQ gives blurry output → increase the quality setting before conversion
• !Colors look different in IIQ than MNG → check color profile mismatch (sRGB vs Adobe RGB)
• !File size changed more than expected → IIQ uses different compression, file size differences of 2-5x are normal
• !Transparent areas in MNG turned white in IIQ → IIQ may not support transparency
