What is PS?

PostScript, page description language for printing and vector graphics — stored as application/postscript — uses lossless encoding to handle print publishing, vector illustrations, desktop publishing. Typical file sizes: varies by content.

What is ARW?

Sony Alpha Raw (ARW) is Sony's proprietary raw image format containing unprocessed sensor data from Sony Alpha and Cyber-shot cameras.

When Should You Use PS vs ARW?

PS vs ARW: Key Differences

• •The core technical difference: PS relies on lossless compression whereas ARW uses lossless compression.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: ARW lacks transparency support.
• •Storage footprint: varies for PS vs 20-40MB per photo for ARW.
• •Primary audience: PS is built for print publishing, vector illustrations, desktop publishing scenarios, while ARW focuses on sony camera post-processing, professional editing — pick the format that matches your output requirement.

Advantages of PS

• ✓PS applies lossless compression specifically calibrated for Print publishing, vector illustrations, desktop publishing.
• ✓PS enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓PS guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find PS support built into virtually every tool that handles Print publishing, vector illustrations, desktop publishing — no plugins or converters needed.

Advantages of ARW

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

Common Use Cases for PS to ARW Conversion

• Graphic design projects
• E-commerce product images
• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations
• Mobile app UI assets

Industry Applications

Best Practices for PS to ARW Conversion

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

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