When Should You Use RAW vs PSB?

RAW vs PSB: Key Differences

• •RAW and PSB diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both RAW and PSB 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: PSB supports transparency, so alpha information is preserved during conversion.
• •RAW files are typically 20-50MB per photo depending on camera while PSB files range Can exceed 2GB
• •Use case fit: RAW targets professional photography, post-processing, editing and PSB targets large-format graphic design, billboard artwork — your choice depends on which workflow stage you are serving.

• ✓File size management with RAW: larger files guaranteed to match the original exactly.
• ✓Every major application in the Professional photography, post-processing, editing space supports RAW natively.

Advantages of PSB

• ✓At its core, PSB relies on lossless encoding — a design choice that makes it perfect for Large-format graphic design, billboard artwork.

Best Practices for RAW to PSB Conversion

• →Before converting RAW to PSB, 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 PSB — you cannot recover detail lost during lossy compression
• →Check the color profile: RAW images may use a wider gamut than PSB 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

• !File size changed more than expected → PSB uses different compression, file size differences of 2-5x are normal
• !Transparent areas in RAW turned white in PSB → PSB may not support transparency
