BZ2 in het kort
BZ2
bzip2 is closely associated with Julian Seward's block-sorting compressor work and became a common alternative to gzip in source distribution and archival workflows.
LZ4 in het kort
LZ4
The LZ4 project positioned the format around extremely fast compression and decompression, which helped it stand out from ratio-first compressor families.

Veelgestelde vragen
Why convert BZ2 to LZ4?
Convert to LZ4 when fast compression and fast restore matter most.
It is a good target for transient archives, backups that must be restored quickly, CI artifacts, log shipping, and large data movement inside infrastructure you control.
Use it when wall-clock speed is more important than the smallest final file.
For internet distribution or long-term cold storage, xz or zstd may make more sense; LZ4 shines in performance-sensitive internal pipelines.
What changes when converting BZ2 to LZ4?
This conversion changes how the format behaves in downstream tools and delivery environments.
What should I review after converting BZ2 to LZ4?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
