Drop your existing ZIP archive
Choose split mode: by size (e.g. 50 MB chunks) or by entry count (e.g. 1000 files per part)
Download every part — each is a self-contained valid ZIP, not raw byte slices
0 bytes uploaded. Archive Splitter runs entirely in your browser using fflate, zip.js, and libarchive WASM. Your archive files never leave your device.
Multi-Part Creator builds a fresh ZIP from input files and slices the bytes. Splitter takes an existing ZIP and rebuilds N self-contained ZIPs each containing a subset of entries — every part opens independently.

Build a ZIP, then split it into fixed-size parts (.zip.001, .zip.002, …) for email attachment limits, FAT32 volumes, or USB drives. Browser-native.
