When Should You Use ICO vs DNG?

ICO vs DNG: Key Differences

• •ICO uses lossless compression while DNG uses lossless compression — both take the same approach to file size management.
• •Since both ICO and DNG use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A
• •ICO files are typically 1-16KB while DNG files range 15-40MB per photo
• •Use case fit: ICO targets favicons, application icons, platform-specific assets and DNG targets raw archival, cross-platform photography workflow — your choice depends on which workflow stage you are serving.

Troubleshooting ICO to DNG Conversion

• !DNG shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted DNG image looks washed out → the source ICO likely uses a wider color space than DNG supports
• !DNG file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted DNG looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
