SRW
Samsung RAW Image
SRW is Samsung's proprietary RAW image format used by their NX-series mirrorless cameras. These cameras featured APS-C sensors with 14-bit ADC, delivering impressive image quality before Samsung exited the camera market in 2015. SRW files preserve the complete sensor readout, offering full post-processing flexibility for white balance, exposure, and color adjustments. Lossless RAW |
JXL
JPEG XL
JPEG XL is the next-generation image codec standardized as ISO/IEC 18181 in 2022. It provides superior compression for both lossy and lossless modes, supports HDR, wide color gamuts, progressive decoding, and animation. JXL is the technically most advanced image format available, designed to eventually replace JPEG across all use cases. Lossless Modern |

Why Convert SRW to JXL?
Converting SRW to JXL is especially important because Samsung has discontinued its camera division, making SRW an orphaned format with no future updates. As software vendors gradually drop SRW support from their RAW processors, having developed copies in JPEG XL — an active ISO standard — ensures your Samsung NX photographs remain accessible and viewable for decades to come.
Samsung's NX cameras, particularly the NX1 and NX500 with their 28 MP BSI sensors, produced excellent image quality that rivals contemporary competition. These photographs deserve a modern format that does justice to their quality. JPEG XL's advanced compression preserves the full tonal range, color accuracy, and detail that Samsung's sensors captured — far better than downgrading to 8-bit JPEG.
The urgency of SRW conversion increases over time. Samsung's own RAW processing software is no longer maintained, and third-party support may eventually be dropped for this niche format. Open-source tools like rawpy, dcraw, and LibRaw currently handle SRW files well, but converting now while support is robust is a prudent preservation strategy. JXL's ISO standardization guarantees the output format will remain supported.
For Samsung NX photographers who built significant collections during the 2010-2015 era, JXL offers both practical and archival benefits. Practically, JXL files can be shared, viewed on modern devices, and posted online — none of which SRW files can do. Archivally, lossless JXL preserves the developed image at 35% better compression than PNG, making it the most space-efficient lossless option for long-term storage.
Key Benefits of Converting SRW to JXL:
- Format Preservation: Convert from discontinued format to active ISO standard
- NX Quality Honored: Wide gamut and HDR preserve Samsung sensor quality
- Future-Proof: JXL backed by ISO/IEC 18181, SRW has no future
- Storage Efficiency: 70-85% smaller than original SRW files
- Modern Accessibility: View on current browsers, phones, and computers
- Lossless Option: Pixel-perfect preservation at 35% better than PNG
- Progressive Loading: Fast preview for web galleries and sharing
Practical Examples
Example 1: Preserving Samsung NX1 Professional Work
Scenario: A photographer who used the Samsung NX1 professionally needs to preserve their portfolio in a future-proof format before SRW software support disappears.
Source: event_coverage_0523.srw (35 MB, 6480x4320px, 14-bit BSI) Conversion: SRW → JXL (lossless, 16-bit) Result: event_coverage_0523.jxl (6.5 MB, 6480x4320px, 16-bit) Portfolio preservation: - 12,000 SRW files (2014-2016): 420 GB - 12,000 JXL lossless: 78 GB (81% reduction) ✓ 28 MP BSI sensor quality fully preserved ✓ Format will remain readable for decades (ISO standard) ✓ 342 GB of storage freed ✓ Files viewable without Samsung RAW software ✓ Original SRW kept as archival master
Example 2: NX500 Travel Photography Web Gallery
Scenario: A travel photographer has thousands of SRW files from a Samsung NX500 and wants to create a beautiful online portfolio with fast loading.
Source: marrakech_market.srw (32 MB, 6480x4320px, 14-bit RAW) Conversion: SRW → JXL (quality 92) Result: marrakech_market.jxl (1.4 MB, 6480x4320px) Web gallery performance: ✓ 1.4 MB for a full 28 MP image ✓ Samsung's vibrant color science preserved ✓ Progressive decode for instant gallery browsing ✓ Fallback to WebP/JPEG via picture element ✓ 80-image gallery under 112 MB total
Example 3: Batch Migration of NX Camera Family Photos
Scenario: A Samsung NX camera owner has years of family photos in SRW format and worries about long-term accessibility as the format becomes obsolete.

Frequently Asked Questions (FAQ)
Q: Why is SRW conversion particularly urgent?
A: Samsung exited the camera market in 2015 and no longer maintains its RAW processing software. SRW is an orphaned format — no new software will be written specifically for it, and existing support may be dropped over time. Converting to JXL (ISO standard) ensures your photographs outlive the format they were captured in.
Q: Which Samsung cameras produce SRW files?
A: The Samsung NX mirrorless camera line: NX10, NX100, NX200, NX210, NX300, NX300M, NX500, NX1, NX1000, NX1100, NX2000, NX3000, NX Mini, and NX Mini 2. The NX1 (28 MP BSI, 2014) and NX500 (28 MP BSI, 2015) were the final and most capable models.
Q: Will the NX1's excellent image quality be preserved?
A: Yes. The NX1's 28 MP BSI sensor with 14-bit ADC produced remarkably detailed images with excellent dynamic range. JXL's 16-bit lossless mode preserves every bit of that quality. In lossy mode at quality 92+, the difference from lossless is invisible. The Samsung color science and BSI sensor advantages are faithfully captured.
Q: Can Samsung's Picture Wizard profiles be applied?
A: Picture Wizard profiles (Standard, Vivid, Portrait, etc.) are embedded in SRW metadata. RAW development software like Lightroom and RawTherapee can apply these profiles during processing. The resulting colors are then encoded into the JXL output, preserving the intended look.
Q: Is there a risk of losing SRW support in current software?
A: Yes. Adobe Lightroom still supports SRW, but there is no guarantee for future versions. Open-source tools (dcraw, rawpy, LibRaw) are more likely to maintain legacy format support long-term. Converting now while multiple tools still read SRW is the safest approach for preserving your photographs.
Q: How does JXL compare to converting SRW to DNG for archival?
A: DNG preserves the raw sensor data for future re-processing — it is a RAW archival format. JXL stores the developed (processed) image — it is a delivery and distribution format. Ideally, convert SRW to both: DNG for the raw master archive, and JXL for the developed reference copies that can be viewed and shared.
Q: What quality setting best preserves NX sensor quality?
A: For archival, use lossless (quality 100). For general use, quality 93-95 is recommended — it preserves the full visual quality of the NX sensor while reducing file sizes by 5-8x compared to lossless. Quality below 88 may begin to simplify subtle gradients that the 14-bit sensor captures.
Q: Can I still use Samsung's i-Function lens data after conversion?
A: The i-Function lens correction data (distortion, vignetting, chromatic aberration) is applied during RAW development. The JXL output contains the corrected image. Original i-Function metadata may be preserved in EXIF for reference, but the corrections themselves are baked into the developed pixels.
