Split
Split ZIP into Smaller Parts
Upload a ZIP and split its contents into multiple smaller ZIPs, each under your chosen size limit. Use presets for Gmail (25 MB), Outlook (20 MB), WhatsApp (100 MB), or set a custom limit. Each output ZIP is a complete, independent archive — not a multi-volume split archive.

ZIP (multiple parts)
Common uses
- Break a large project ZIP into email-sized parts
- Split a backup ZIP for WhatsApp sharing
- Prepare parts for a portal with an upload limit
- Send a large photo album in stages
Limitations
- Output archives are separate ZIP files, not a multi-volume split archive (.zip.001, .zip.002). Recipients receive multiple complete ZIPs.
- Files that are individually larger than the target part size cannot be split and will be placed in their own ZIP.
- The recipient must extract each part separately.
Frequently asked questions
No. Each output ZIP is an independent, complete archive. The files from the original ZIP are distributed across them. Each part can be extracted on its own.
Files are added to each part in order until the part reaches the size limit. Then a new part starts. File order from the original ZIP is preserved.
That file gets its own ZIP. Individual files cannot be split.
