ZIP Inspector
Look inside a ZIP without extracting it. See every filename, its compressed and original size, its compression ratio, and the folder structure — before you commit to unpacking something you were sent. It is free, needs no account, and adds no watermark to your result.

Run up to 100 compatible files (250 MB total), receive a ZIP when multiple results need packaging, and choose the download name.
The ZIP central directory is read and reported as JSON. Only the index is parsed; no member is decompressed and nothing is written to disk.
Safely extract one ZIP archive per job with path-traversal, member-count and total output-size limits.
Convert TAR or TAR.GZ archives into ZIP while safely validating archive member paths.
Compress multiple uploaded files into a standard ZIP archive with preserved filenames and DEFLATE compression.
Detect a file type from its signature, extension and parsable format information instead of trusting the filename alone.
