ZIP Inspector
File
Drag in a ZIP archive and instantly see the file tree, individual sizes, and total uncompressed size. Click any text file (source code, JSON, configs) for an inline preview, or download a single entry without extracting the whole archive. Powered by fflate, runs entirely in your browser — no upload, no temp files on disk.
How to use
- Drop a .zip file or click to choose one.
- Browse the entries; click any file name to preview.
- Use the per-row Download button to save a single file.
Frequently asked questions
- Is the ZIP uploaded?
- No. fflate unpacks the archive in memory inside your browser — the ZIP and its contents never leave your device.
- Which ZIPs are supported?
- Standard ZIP archives compressed with the Deflate algorithm (what most tools produce). Encrypted ZIPs and Zip64-only archives may not open.
- Why are some files shown as 'binary'?
- The preview decodes as UTF-8 text. If the first bytes contain many non-printable characters, the file is treated as binary and the preview is skipped — but you can still download it.
- How big a ZIP can I open?
- Limited by your browser's available memory. Hundreds of MB usually works; multi-gigabyte archives may be slow or fail to load.
