Bzip2 Compressed
Format sumberBzip2 provides higher compression ratios than gzip at the cost of slower speed. It is commonly used for .tar.bz2 archives in Linux distributions where smaller download sizes are preferred.
LZ4 Compressed
Format tujuanLZ4 is an extremely fast lossless compression algorithm focused on speed over compression ratio. It can compress at over 500 MB/s per core and decompress at multiple GB/s, making it the standard choice for real-time and in-memory compression.
Mengapa mengonversi BZ2 ke LZ4
Mengubah BZ2 ke LZ4 memastikan file Anda dapat dibuka di semua perangkat, aplikasi pengeditan, dan portal web yang mewajibkan format LZ4.

BZ2 vs LZ4 — Keunggulan dan keterbatasan
Apa kelebihan utama masing-masing format, dan di mana kekurangannya.
BZ2 Keunggulan
- 10-15% smaller than gzip for the same content.
- Block-based — partial recovery possible from corrupted archives.
- Patent-free, open-source reference implementation.
- Stable for 30+ years with no breaking changes.
Keterbatasan
- Much slower than gzip — 3-5× the compression time.
- Still slower than xz and zstandard at modern levels.
- Single-threaded in reference; pbzip2 fixes this.
LZ4 Keunggulan
- Decompression speed — approaches memcpy throughput.
- Very fast compression — can keep up with SSD write speeds.
- Stable format — reference implementation unchanged for years.
- Widely deployed in databases, filesystems, and kernels.
- BSD-licensed library.
Keterbatasan
- Compression ratio lags gzip by 20-30%.
- Not designed for long-term archival where ratio matters.
- Older than zstd, which beats LZ4 at comparable speed at slightly better ratio.

BZ2 vs LZ4 — Ukuran file umum
Perkiraan ukuran file untuk skenario umum.
BZ2
- Text file 20-30% of original
- Source code archive 15-25% of original
- Linux kernel source (.tar.bz2) ~150 MB
LZ4
- Text file 40-60% of original
- Already-compressed data (JPEG, MP4) 99%+ (no gain)
- Database page (typical) 55-70% of original
Kualitas & Kompatibilitas
Pipeline konversi native memproses BZ2 ke LZ4 dengan parameter terbaik agar detail dan struktur tetap utuh.
Tips untuk Hasil Terbaik
- Selalu gunakan file sumber BZ2 dengan kualitas terbaik yang Anda miliki.
- Periksa lencana penghematan ukuran file setelah konversi selesai.
- Gunakan fitur rantai 1-klik jika Anda perlu mengompres hasil LZ4 ke ukuran KB tertentu.
Keterbatasan
Hingga 25 MB pada paket gratis (250 MB Starter, 1 GB Pass 24 Jam & Pro). File yang dikunci kata sandi atau DRM harus dibuka terlebih dahulu.
Pertanyaan Umum
Yes. The free tier accepts files up to 25 MB without registration, email capture or watermarks; paid plans go up to 2 GB. Paid plans raise the size cap, enable batch conversions and provide a REST API for automation, but nothing on the free tier is quality-limited — the output is exactly the same as on any paid plan.
Yes — because BZ2 and LZ4 use different compression codecs, every entry is decompressed from the BZ2 and re-compressed for the LZ4. The uncompressed data is identical on both sides, and the re-compression happens entirely inside our processing container.
Uploads run over HTTPS, files are processed in isolated containers, and both the source BZ2 and the LZ4 output are auto-deleted within two hours. No account is required, file contents are never logged, and KaijuConverter does not use uploads for AI training. The paid plan adds a signable data-processing agreement for regulated workflows.
Usually yes, modestly, when the original BZ2 used an older codec like Deflate. Against modern LZMA2 / Zstd LZ4 containers expect 10-30% savings on mixed content and almost no change on pre-compressed payloads. Advanced → compression level lets you trade speed for ratio.
Most files finish in well under a minute. Small images and documents are typically ready in a few seconds; large video or audio files scale roughly with duration. Upload speed from your network is usually the dominant factor, not server time.
Yes. Provide the password during upload; we use it only to decrypt inside the processing container and never log or persist it. The resulting LZ4 can be re-encrypted with a password of your choice (AES where the target format supports it).
