SnapToolsZIP Inspector
Runs in your browserSee exactly what's inside a ZIP archive — file names and sizes — without extracting or uploading anything. The safest first move for an archive you don't fully trust.
About this tool
Before extracting an unfamiliar ZIP file onto your machine, it's worth knowing what's actually in it — how many files, what they're named, roughly how large. This tool reads the archive's directory listing entirely in your browser and shows you that summary without writing any decompressed content to disk, which makes it a genuinely lower-risk first look than extracting outright.
How to use
- Add a ZIP file.
- Click Inspect.
- Review the file listing before deciding whether to extract.
When to use this tool
- Checking what's inside a ZIP before extracting it onto your machine.
- Confirming a downloaded archive contains what you expect before unpacking it.
- Quickly counting or sizing the files in an archive without a desktop tool.
Tips
- This lists names and sizes only — it doesn't scan for malware. Treat an unfamiliar archive with the same caution either way.
- Ready to open the files? Use the ZIP Extractor next.
Limitations
- Lists file names and sizes only — it doesn't scan contents for malware, so treat an unfamiliar archive with the same caution either way.
FAQ
- Is the ZIP file uploaded?
- No. The listing is read entirely in your browser, and nothing inside the archive is decompressed to disk.
- Does this check for malware?
- No. It only lists file names and sizes. Still treat unfamiliar archives with the same caution you would otherwise.
