How to Open a ZIP File Safely
ZIP files are the usual way to send several files at once. Most are harmless, but an archive from someone you don’t know can hide things that are worth checking before you extract it.
Open ZIP ExtractorStep by step
Open the ZIP Extractor
It runs in your browser; the archive isn’t uploaded.
Choose the ZIP file
TextVix lists every file inside, with its folder and size, and checks each one.
Review anything that was skipped
Encrypted files, damaged files and entries with unsafe paths or names are listed separately with the reason.
Download what you need
Download single files, or everything as a new, clean ZIP that keeps the folder structure.
What can go wrong
A “zip bomb” is a small archive that expands to an enormous size to fill your disk or memory. A path trick (sometimes called Zip Slip) names a file like ../../something so a careless extractor writes it outside the folder you chose. And archives often contain programs or scripts that look like documents.
What TextVix checks
Every offset and size in the archive is checked before use, unpacking stops at a size limit based on the bytes actually produced, each file is verified against its checksum, overlapping entries are refused, and unsafe names are never offered for download. Nothing inside the archive is opened or run.
Built into your computer
Windows: right-click the ZIP and choose Extract All. macOS: double-click it to extract with Archive Utility. iPhone and iPad: tap it in the Files app. These are fine for archives you trust.
After extracting
Be wary of programs (.exe, .msi, .app, .dmg), scripts (.js, .vbs, .bat, .ps1, .sh) and Office files with macros that you weren’t expecting, even if the email looked familiar. When in doubt, ask the sender through another channel.
