What is RAR?

RAR is a proprietary archive format that offers strong compression. Note: GoConvertFile supports RAR extraction only due to patent restrictions on RAR creation.

What is LZ4?

LZ4 (application/x-lz4) uses lossless compression optimized for real-time compression, log files, game assets. LZ4, extremely fast compression algorithm for real-time use

When Should You Use RAR vs LZ4?

Use RAR When...

Reach for RAR when your priority is file sharing, compressed archives — its efficient compression makes sharing fast and storage minimal.

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.

RAR vs LZ4: Key Differences

•The core technical difference: RAR relies on lossy compression whereas LZ4 uses lossless compression.
•The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
•Alpha channel support: LZ4 handles transparency.
•File sizes: RAR files typically range Smaller than equivalent ZIP archives and LZ4 files N/A.
•Use case fit: RAR targets file sharing, compressed archives and LZ4 targets real-time compression, log files, game assets — your choice depends on which workflow stage you are serving.

Advantages of RAR

✓RAR compresses data using lossy methods, keeping file sizes manageable for File sharing, compressed archives.
✓Industry-wide support means RAR files open anywhere — from legacy systems to the latest devices.
✓Small file sizes make RAR ideal for email, web uploads, and cloud storage.
✓From professional software to open-source alternatives, RAR works out of the box.

Advantages of LZ4

✓LZ4 compresses data using lossless methods, keeping file sizes manageable for Real-time compression, log files, game assets.
✓Industry-wide support means LZ4 files open anywhere — from legacy systems to the latest devices.
✓Lossless quality makes LZ4 the gold standard for archival and master copies.
✓From professional software to open-source alternatives, LZ4 works out of the box.

Best Practices for RAR to LZ4 Conversion

→Before converting RAR 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 RAR to LZ4 Conversion

!LZ4 archive is corrupted after converting from RAR → 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 RAR archives to LZ4 times out → split into smaller volumes or reduce compression level

FAQs

Is converting RAR to LZ4 free?

Yes, GoConvertFile offers free conversion of RAR to LZ4 for files up to 100MB. No registration required.

How long does it take to convert RAR to LZ4?

Most RAR to LZ4 conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is LZ4 best used for?

LZ4 is ideal for real-time compression, log files, game assets. LZ4, extremely fast compression algorithm for real-time use

Does converting RAR to LZ4 lose quality?

No, converting RAR to LZ4 does not cause additional quality loss â€” LZ4 uses lossless compression. However, any artifacts already present in the original RAR file will persist in the LZ4 output.

What file size should I expect after converting RAR to LZ4?

LZ4 files are typically 2-5x larger than equivalent RAR files because LZ4 preserves all pixel data. This is expected and necessary for lossless quality.
