About ZIP files
Test ZIP archives from 1 MB to 100 MB are available free, for upload testing, extraction verification, and transfer-speed measurement.
A normal ZIP's size depends entirely on what it contains, but the archives here are trimmed to land on the stated size exactly, so they can be used directly for boundary-value testing.
Typical uses
- Testing size limits on ZIP upload
- Confirming that server-side extraction caps the uncompressed size — the defence against zip bombs
- Confirming that entry names containing
../are rejected — the Zip Slip defence - Simulating backup jobs and transfer bandwidth
For why compression ratios differ so much between files, see Why ZIP compression ratios vary so much.
