## Frequently asked questions

### What is the difference between ZIP and 7Z?

7Z generally offers a higher compression ratio than ZIP, resulting in smaller file sizes for the same data.

### Can I convert multiple files at once?

This tool currently supports processing one ZIP file at a time.

### What does the compression level mean?

The level ranges from 0 to 9, where 0 provides the fastest speed with minimal compression and 9 provides the smallest file size with longer processing time.

### Is there a file size limit?

Yes, the tool supports ZIP files up to 500MB.

### Do I need to install 7zip software?

No, the conversion is handled entirely on our servers using the 7zip engine.
