Questions
No. Every tool runs in your browser. The page downloads its code once; your files never leave your device.
Yes. Create ZIP can encrypt every file with AES-256. Open the result with 7-Zip, Keka or WinZip; the built-in ZIP openers of Windows and macOS may not support AES encryption.
Extract ZIP refuses entries with absolute paths or .. segments, archives with more than 10,000 entries or more than 2 GB unpacked, and entries that expand more than 200 to 1. Nothing is written to your disk until you save a file.
Checksums, duplicate finding and ZIP extraction read files in chunks, so very large files work, up to 2 GB each. Creating a ZIP is best kept under about 1 GB in total because the result is held in memory.
