## Which file tool should I choose?

File Inspector identifies file signatures and sizes. ZIP Creator bundles files, and ZIP Extractor lists and extracts archive entries. Batch Rename downloads renamed copies in a ZIP. Compare files and checksums help verify contents. Encrypt File creates a password-protected xfiles container that Decrypt File restores.

### Are my files uploaded?

No. File tools read and process your selected files in this browser. Download results before closing the tab.

### What are the archive limits?

Select up to 150 MB in total. ZIP extraction is limited to 1,000 entries and 300 MB of expanded data. Other archive formats and encrypted ZIP archives are not supported.

### How does file encryption work?

Encrypt File uses AES-256-GCM with a password-derived key, a fresh random salt and a fresh IV. Restore its .xfiles output with Decrypt File and the same password. It does not create a password-protected ZIP archive.
