What is IMG?

Raw Disk Image (IMG) is a sector-by-sector byte copy of a disk or floppy drive, used for cloning and forensic imaging.

What is LZ4?

LZ4, extremely fast compression algorithm for real-time use — stored as application/x-lz4 — uses lossless encoding to handle real-time compression, log files, game assets. Typical file sizes: varies by content.

When Should You Use IMG vs LZ4?

Use IMG When...

Reach for IMG when your priority is floppy disk backups, forensic disk imaging — its uncompromising quality ensures every detail is preserved.

Use LZ4 When...

Reach for LZ4 when your priority is real-time compression, log files, game assets — its uncompromising quality ensures every detail is preserved.

IMG vs LZ4: Key Differences

•IMG and LZ4 diverge on compression: lossless compression for the source, lossless compression for the target.
•Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
•Transparency: Supported in LZ4
•Storage footprint: Exactly equals source disk size for IMG vs varies for LZ4.
•Primary audience: IMG is built for floppy disk backups, forensic disk imaging scenarios, while LZ4 focuses on real-time compression, log files, game assets — pick the format that matches your output requirement.

Advantages of IMG

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

Best Practices for IMG to LZ4 Conversion

→Before converting IMG to LZ4, confirm the archive is not corrupted — a damaged source produces a damaged target
→LZ4 is a reliable choice for cross-platform archiving needs
→Set a strong password if the archive contains sensitive data — encryption is applied during the conversion
→Use the highest compression level for long-term storage and faster compression for temporary files
→Test extracting a single file from the converted archive to confirm integrity

Troubleshooting IMG to LZ4 Conversion

!LZ4 archive is corrupted after converting from IMG → try repairing with built-in archive tools
!Password not working on the converted LZ4 archive → verify case sensitivity and special characters
!Extraction of LZ4 fails → the archive may be incomplete; try downloading and converting again
!Converting large IMG archives to LZ4 times out → split into smaller volumes or reduce compression level
