🗜️ ZIP Password Protector
Lock any ZIP archive behind a strong password with modern AES-256 encryption that runs entirely in your browser.
Ultimate Archive Tool
Compress folders, extract ZIPs, inspect archive contents, and optionally protect everything with password-based AES-256 encryption. Everything runs locally in your browserâno uploads required.
Compress files
Drop files or folders, tweak compression, and generate a download-ready archive.
Extract & inspect
Open any ZIP file to see its contents, verify integrity, or download individual files.
How to use this tool
- Choose files to compress or drag a whole folder into the compressor.
- Adjust the compression level, toggle password protection, then create your archive.
- Open any ZIP in the extractor tab to browse contents, verify sizes, and download individual items.
Compression presets
- DEFLATE at level 6 balances speed and size for everyday archives.
- Switch to STORE for zero recompression when packaging already-compressed media like JPEG or MP4.
- Use passwords to wrap the archive in AES-256 encryptionâonly people with the password (and this tool) can open it.
Inspect before sharing
- Review the file list to catch stray secrets before emailing archives.
- Download a single file without extracting the entire archive on your machine.
- Compare compressed versus uncompressed sizes to spot healthy compression ratios.

- This tool applies modern AES-256-GCM encryption to the ZIP payload. Only ToolHop's archive tool can unlock these encrypted archives, ensuring strong protection with a memorable password.
- Where does processing happen?
- All compression, extraction, and encryption happens entirely within your browser. Files never leave your device.
- Can I preview large archives?
- Yesâarchives are streamed into memory on demand. For massive ZIPs, load times depend on your device, but no background uploads occur.
