What is DWG?

AutoCAD DWG is the native binary file format for AutoCAD, the industry standard for professional CAD design and drafting.

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 DWG vs IIQ?

DWG vs IIQ: Key Differences

• •DWG uses lossless compression while IIQ uses lossless compression — both take the same approach to file size management.
• •Since both DWG and IIQ use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •How transparency is handled: IIQ supports transparency, so alpha information is preserved during conversion.
• •File sizes: DWG files typically range Smaller than DXF due to binary encoding and IIQ files 50-150MB per image from medium-format backs.
• •DWG is optimized for professional cad designs, engineering blueprints while IIQ is designed for professional studio photography, digital back capture — choose based on your specific workflow needs

Advantages of DWG

• ✓At its core, DWG relies on lossless encoding — a design choice that makes it perfect for Professional CAD designs, engineering blueprints.
• ✓You won't run into compatibility issues with DWG — it's a universal standard across platforms.
• ✓File size management with DWG: larger files guaranteed to match the original exactly.
• ✓Every major application in the Professional CAD designs, engineering blueprints space supports DWG natively.

Advantages of IIQ

• ✓IIQ uses lossless compression tailored for Professional studio photography, digital back capture.
• ✓IIQ is supported natively on virtually every device, browser, and operating system.
• ✓IIQ files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓IIQ integrates seamlessly with all major photo editing tools and workflows.

Common Use Cases for DWG to IIQ Conversion

• Blog and article illustrations
• Mobile app UI assets
• Product photography for marketplaces
• Digital art portfolios
• Brochure and flyer design
• Newsletter graphics

Industry Applications

Best Practices for DWG to IIQ Conversion

• →Before converting DWG 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: DWG 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 DWG to IIQ Conversion

• !Converting DWG to IIQ gives blurry output → increase the quality setting before conversion
• !Colors look different in IIQ than DWG → 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 DWG turned white in IIQ → IIQ may not support transparency
