What is ORF?

Olympus Raw Format (ORF) contains raw sensor data from Olympus OM-D, PEN, and other Olympus digital cameras.

What is PCX?

PCX (PC Paintbrush) is a legacy raster image format from the early days of DOS, originally created for ZSoft's PC Paintbrush.

When Should You Use ORF vs PCX?

ORF vs PCX: Key Differences

• •The core technical difference: ORF relies on lossless compression whereas PCX uses lossless compression.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Alpha channel support: PCX lacks transparency support.
• •File sizes: ORF files typically range 15-40MB per photo and PCX files Moderate, similar to uncompressed formats.
• •Use case fit: ORF targets olympus camera raw processing and PCX targets legacy graphics, retro computing — your choice depends on which workflow stage you are serving.

Advantages of ORF

• ✓ORF uses lossless compression tailored for Olympus camera raw processing.
• ✓ORF is supported natively on virtually every device, browser, and operating system.
• ✓ORF files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓ORF integrates seamlessly with all major creative tools and workflows.

Advantages of PCX

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

Common Use Cases for ORF to PCX Conversion

• E-commerce product images
• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations
• Mobile app UI assets
• Product photography for marketplaces

Industry Applications

Best Practices for ORF to PCX Conversion

• →When converting ORF to PCX, check whether PCX supports transparency — if not, your transparent areas will be filled with a solid color
• →Use PCX for maximum quality archival and ORF for lossless workflows
• →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 ORF to PCX Conversion

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