🗜️ ZIP Viewer
Peek inside any ZIP archive, inspect file sizes, and download individual files without extracting everything locally.
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.
FAQ
- Does password protection create standard ZIP passwords?
- 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.
