How to use this tool
View the contents and metadata of any archive without extracting it.
Open the Inspect Archive tool
Visit makemyzip.com/inspect-archive. The format is detected from the file’s magic bytes.
Drop any supported archive
ZIP, 7z, RAR, TAR, and GZ all work. Drag the file onto the dropzone or click to pick it.
Read the summary
See the format, file count, total uncompressed and compressed sizes, compression ratio, and whether the archive is encrypted.
Browse the file tree
Expand folders to inspect individual entries with their sizes. No extraction takes place — you are only reading the index.
Frequently asked questions
Will Inspect Archive extract anything to disk?
No. It only reads the central directory / file index. The compressed bytes are never written out.
Which formats are supported?
ZIP, 7z, RAR, TAR, and GZ. Format detection is automatic via magic bytes, with extension as a fallback.
Can I inspect a password-protected ZIP?
Yes — the file list is visible because ZIP keeps filenames in the central directory unencrypted. Sizes and encryption flags are shown too.
Why does the compression ratio matter?
A ratio close to 1.0 means the archive is already as small as it gets — switching formats or levels will not shrink it further. Useful before sending or uploading.
