Archive Viewer

Free Online ZIP Archive Viewer

Sometimes you just need to know what's inside a ZIP file before deciding what to do with it - how many files it contains, how large they are, or whether a specific file is in there at all. LovePDFImg's Archive Viewer reads a ZIP's directory listing and shows you everything: file names with their full paths, individual file sizes, compression ratios, and an overall summary.

Unlike the ZIP Extractor, this tool doesn't decompress or download anything - it only reads the lightweight directory information stored at the end of the ZIP file, so even large archives preview almost instantly. If you decide you do want to pull files out afterward, head over to the ZIP Extractor. Everything here runs locally in your browser; nothing is uploaded.

This is a useful first step before downloading anything from an unfamiliar archive - confirming what's inside, checking the total size before committing to extraction, or verifying a specific file is present without opening a full extraction workflow.

Key Features

• Full file listing: See every file and folder path inside the archive.
• Size and compression details: Compare compressed vs uncompressed size per file.
• Instant preview: No decompression needed, so even large ZIPs load fast.
• Summary totals: Get a quick count and overall size for the whole archive.
• Browser-based processing: Your file never leaves your device.
• Free and unlimited: No account, no daily cap.

Who Uses Archive Viewer?

IT support staff: Quickly verify the contents of a ZIP file before deciding how to handle it.

Developers: Check what's included in a downloaded package or dependency archive before extracting.

Everyday users: Confirm a specific file exists in an archive before spending time extracting everything.

Businesses: Preview a received ZIP's contents before deciding whether to fully extract or forward it.

Why Choose LovePDFImg's Archive Viewer?

Most ways to check a ZIP's contents require opening it in a full file manager or extraction tool, which can be slow for very large archives. LovePDFImg's Archive Viewer reads only the lightweight directory listing, giving you an instant preview without any decompression step. There's no account requirement, no daily cap, and it's completely free.

Technical Explanation: ZIP Central Directory

Every ZIP archive ends with a "central directory" - a compact index listing each contained file's name, path, compressed size, uncompressed size, and location within the archive. Because this directory is small and stored separately from the actual compressed file data, reading it doesn't require processing any of the archive's bulk content, which is why Archive Viewer can preview even multi-gigabyte ZIPs almost instantly, unlike tools that need to decompress data to report on it.
