What is JNG?

JPEG Network Graphics (JNG) is a hybrid format using JPEG-compressed image data with optional PNG-compressed alpha channel.

What is SRW?

Samsung Raw (SRW) contains raw sensor data from Samsung NX series cameras.

When Should You Use JNG vs SRW?

Use JNG When...

Reach for JNG when your priority is legacy web animation, lossy image sequences — its efficient compression makes sharing fast and storage minimal.

Use SRW When...

Reach for SRW when your priority is samsung camera raw post-processing — its uncompromising quality ensures every detail is preserved.

JNG vs SRW: Key Differences

  • •JNG uses lossy compression while SRW uses lossless compression — this is the fundamental technical difference between the two formats.
  • •Converting from JNG to SRW changes compression type: lossless source becomes larger but with full quality preservation.
  • •How transparency is handled: SRW supports transparency, so alpha information is preserved during conversion.
  • •JNG files are typically Smaller than MNG for photos while SRW files range 15-40MB per photo
  • •Use case fit: JNG targets legacy web animation, lossy image sequences and SRW targets samsung camera raw post-processing — your choice depends on which workflow stage you are serving.

Advantages of JNG

  • ✓JNG uses lossy compression tailored for Legacy web animation, lossy image sequences.
  • ✓JNG is supported natively on virtually every device, browser, and operating system.
  • ✓JNG files are compact and quick to transfer, even over slow connections.
  • ✓JNG integrates seamlessly with all major web development tools and workflows.

Advantages of SRW

  • ✓SRW compresses data using lossless methods, keeping file sizes manageable for Samsung camera raw post-processing.
  • ✓Industry-wide support means SRW files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes SRW the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, SRW works out of the box.

Best Practices for JNG to SRW Conversion

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

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