Group every entry in an archive by file extension and see counts plus uncompressed and compressed totals. Find dominant file types and dead weight.
Per-job file size, entry count, and batch caps for Type Breakdown. Limits apply to every Archive tool in JAD Apps; upgrade for larger uploads and bigger batches.

0 bytes uploaded. File Type Breakdown Analyser runs entirely in your browser using fflate, zip.js, and libarchive WASM. Your archive files never leave your device.
Size Analyser groups by extension AND folder, with rollup totals. File Type Breakdown is just the extension grouping — simpler, faster, ideal for a quick sanity check.
They are grouped under (no extension). Common cases: README, LICENSE, Makefile, Dockerfile. A high count there usually indicates a source-code archive.
No — extensions are normalized to lowercase before grouping. .JPG and .jpg roll up together. To preserve case, use the Archive Metadata Extractor for the raw entry list.
Break down a ZIP by file type and folder. See which extensions dominate the archive and where the bulk lives. Helps identify low-value bloat. Bar chart included.
Open toolInspect every entry in a ZIP and see compression ratios per file plus the overall archive ratio. Spot already-compressed files that don't benefit from re-zipping.
Open toolSHA-256 every entry inside an archive and group identical files. Spot duplicate logos, libraries, or .DS_Store waste. Reports total bytes recoverable.
