Remove metadata from ZIP (.zip)
Step-by-step: what metadata ZIP contains, how ExifSweep removes it, and what gets preserved.
What ZIP typically leaks
- Archive comment (often the tool that built it)
- Per-entry creation, modify, and access timestamps
- Per-entry external attributes (file permissions, OS hints)
- Extra fields revealing Unicode paths and platform
Why this matters
ZIP is the universal archive format — and the most common way photographers, journalists, and ordinary users bundle a folder of photos to share. Every file inside still carries its own metadata, plus the archive itself leaks creation timestamps and the build tool.
How ExifSweep cleans it
libarchive.js walks every entry inside the browser. Each file is processed individually with its own format pipeline (JPEG/PNG/HEIC/etc. metadata strip). The archive is repacked with timestamps zeroed and the archive comment removed.
What we preserve
All file contents; folder structure; output is a clean ZIP without comments or timestamps.
