Try PZIP on your own files

Upload any file and see how PZIP compares to LZMA, gzip, brotli, and zstd. Free during beta. Your data is never stored.

Baseline:     LZMA-9 (maximum compression)
Verification: Byte-exact round-trip on every file
Guarantee:    Never-worse (PZIP <= LZMA always)
Badge rules:  CRUSHING IT >= 30% saving
              WINNING     >= 10% saving
              COMPETITIVE >  0% saving
              NEVER WORSE =  0% saving (still wins on count)
