Frequently asked questions
Are my files uploaded to a server?
No. Everything runs entirely in your browser using JavaScript. Your files never leave your device.
What compression levels are available?
None (store only — fastest, no size reduction), Fast (level 1 — quick with light compression), Default (level 6 — best balance of speed and size), and Max (level 9 — smallest output, takes longer for large files).
Is there a file size limit?
There is no hard limit — processing happens in your browser, so the practical limit depends on your device's available memory. Files up to several hundred MB work fine on modern devices.
What file types can I zip?
Any file type. Images, documents, code, videos, audio — you can add any combination of files to the ZIP.
Can I extract password-protected ZIPs?
No. Password-protected (encrypted) ZIP files cannot be extracted by this tool. You will need to remove the password first.
