What is PS?

PS (application/postscript) uses lossless compression optimized for print publishing, vector illustrations, desktop publishing. PostScript, page description language for printing and vector graphics

What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

When Should You Use PS vs X3F?

PS vs X3F: Key Differences

• •PS uses lossless compression while X3F uses lossless compression — both take the same approach to file size management.
• •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: X3F supports transparency, so alpha information is preserved during conversion.
• •X3F files tend to be differently sized than PS
• •Primary audience: PS is built for print publishing, vector illustrations, desktop publishing scenarios, while X3F focuses on sigma/foveon camera raw processing — pick the format that matches your output requirement.

Advantages of PS

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

Advantages of X3F

• ✓X3F applies lossless compression specifically calibrated for Sigma/Foveon camera raw processing.
• ✓X3F enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓X3F guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find X3F support built into virtually every tool that handles Sigma/Foveon camera raw processing — no plugins or converters needed.

Common Use Cases for PS to X3F Conversion

• Certificate and badge design
• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing
• Graphic design projects

Industry Applications

Best Practices for PS to X3F Conversion

• →When converting PS to X3F, check whether X3F supports transparency — if not, your transparent areas will be filled with a solid color
• →Use X3F for maximum quality archival and PS for smaller file sizes when quality is less critical
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting PS to X3F Conversion

• !X3F shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted X3F image looks washed out → the source PS likely uses a wider color space than X3F supports
• !X3F file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted X3F looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
