SRW vs PPM Format Comparison
| Aspect | SRW (Source Format) | PPM (Target Format) |
|---|---|---|
| Format Overview |
SRW
Samsung RAW
Samsung's proprietary RAW image format used by Samsung NX series mirrorless cameras. SRW stores unprocessed sensor data, preserving maximum image quality and editing flexibility with full 14-bit color depth from the camera's APS-C sensor. Lossless RAW |
PPM
Portable Pixmap (Netpbm)
A simple uncompressed raster format from the Netpbm family used in image processing pipelines. Lossless Legacy |
| Technical Specifications |
Color Depth: 14-bit RAW
Compression: Lossless Transparency: No Animation: No Extensions: .srw |
Color Depth: Up to 24-bit (RGB)

Why Convert SRW to PPM?
Converting SRW to PPM creates uncompressed intermediate files ideal for image processing pipelines and scientific analysis.
PPM's simplicity makes it perfect for command-line tools, batch processing, and programs that need direct pixel access.
For automated processing workflows with Samsung NX camera data, PPM provides the simplest format with zero decoding overhead.
PPM is the standard intermediate format in Unix/Linux image processing tools like ImageMagick and FFmpeg.
Key Benefits of Converting SRW to PPM:
- Accessibility: Convert Samsung RAW to universally readable format
- Sharing: PPM files can be viewed on any device
- Quality: Professional RAW processing preserves image detail
- Compatibility: PPM works with standard image tools
- Workflow: Integrate Samsung NX photos into modern pipelines
- Storage: Reduce file size from 20-30 MB RAW originals
- Future-Proof: Convert from discontinued format to active standard
Practical Examples
Example 1: Samsung NX Camera Photo Processing
Scenario: A photographer converts Samsung NX1 RAW files to PPM for portfolio publication.
Source: portrait_nx1.srw (25 MB, 6480x4320, 14-bit RAW) Conversion: SRW → PPM Result: portrait_nx1.ppm ✓ Full RAW quality preserved in processing ✓ Compatible with modern platforms ✓ Portfolio-ready output ✓ Professional color accuracy
Example 2: Legacy Samsung NX Archive Migration
Scenario: A photographer migrates Samsung NX300 RAW archives to PPM before the format becomes unsupported.
Source: landscape_nx300.srw (20 MB, 5472x3648, 14-bit RAW) Conversion: SRW → PPM Result: landscape_nx300.ppm ✓ Future-proofed from discontinued format ✓ Accessible without Samsung software ✓ Quality preserved for long-term storage ✓ Modern format compatibility
Example 3: Batch Converting Samsung Event Photos
Scenario: An event photographer batch converts SRW files from a Samsung NX1 shoot to PPM for client delivery.
Source: event_001.srw (28 MB, 6480x4320, 14-bit RAW) Conversion: SRW → PPM Result: event_001.ppm ✓ Fast batch processing ✓ Client-ready deliverables ✓ Professional quality output ✓ Universal device compatibility
Frequently Asked Questions (FAQ)
Q: What is the SRW format?
A: SRW is Samsung's proprietary RAW image format used by Samsung NX series mirrorless cameras (NX1, NX500, NX300, NX3000, etc.). It stores unprocessed 14-bit sensor data.
Q: Is SRW to PPM conversion lossless?
A: The RAW processing step (demosaicing) is inherent to any RAW conversion. The PPM output preserves the full quality of the processed image.
Q: Are Samsung NX cameras still made?
A: No. Samsung discontinued the NX camera line in 2015. Converting SRW files to modern formats ensures long-term accessibility of your photos.
Q: Which Samsung cameras produce SRW files?
A: Samsung NX1, NX500, NX300, NX3000, NX30, NX2000, NX1100, NX1000, NX210, NX200, NX20, NX11, NX10, and NX5 all produce SRW files.
Q: Can I edit the SRW file before converting?
A: Our converter applies standard RAW processing (demosaicing, white balance, exposure). For advanced editing, use Adobe Lightroom or RawTherapee before converting.
Q: How large are SRW files?
A: SRW files are typically 20-30 MB depending on the camera model and sensor resolution. The NX1 produces the largest files at approximately 28 MB each.
Q: Why convert from SRW format?
A: Since Samsung discontinued the NX camera line, SRW support in software is declining. Converting to standard formats like PPM ensures your photos remain accessible.
Q: Are there file size limits?
A: Our converter handles SRW files of any size from Samsung NX cameras. Processing time depends on the sensor resolution.
