Frequently Asked Questions

Are my files uploaded to a server?
No. ZIP operations use JSZip, a JavaScript library running in your browser. Your files never leave your device.
What archive formats are supported?
We currently support the ZIP format, which opens natively on Windows, macOS, iOS and Android without additional software.
Is there a limit on the number of files?
There is no hard limit. For very large collections, performance depends on your browser and device memory.
What compression level is used?
We use DEFLATE at level 6 — a good balance between file size and processing speed, compatible with all standard ZIP tools.
Can I extract password-protected ZIPs?
Not currently — our tool handles standard unprotected ZIP files. Password-protected support is on our roadmap.

What you upload stays on your device. Smart2Office does not track what you process, does not store output files, and does not share your data with third parties. What you create belongs entirely to you.
