Extraction · Compression · Conversion · Analysis · Repair · Security · Batch · Utility. Every tool processes your archives locally with fflate, zip.js, and libarchive WASM — zero bytes uploaded.
Every JAD Archive tool runs entirely in your browser. fflate, @zip.js/zip.js, and libarchive's WASM bridge handle the heavy lifting locally. Open DevTools and watch the Network tab during processing — you'll see zero requests to any server. Your archives never leave your device.

Open toolSee every file inside a ZIP, 7Z, RAR, or TAR before extracting. Tree view, sortable table, byte-accurate sizes — runs entirely in your browser, zero upload.
Open toolGenerate a complete inventory of every file in a ZIP or other archive — name, size, compressed size, ratio, last modified — exported to CSV, JSON, or plain text.
Open toolSome archives contain other archives. Recursively unpack ZIPs inside ZIPs, GZIPs inside TARs, up to a configurable depth. Browser-native, zero upload.
Open toolDrop multiple archives — ZIP, 7Z, TAR — and get a single output ZIP with each source unpacked into its own subfolder. Saves dozens of clicks; great for log review.
Open toolBuild ZIPs from files or folders, AES-256 encrypted archives, multi-part splits for email, and streaming builds for multi-GB datasets.
Drop files and get a perfectly compressed ZIP with the optimal speed/size trade-off. Powered by fflate level 6 — the universal sweet spot. Zero upload.

Open toolDrag a folder from your file manager and ZIP it preserving every subfolder, filename, and timestamp. Powered by fflate and the webkitdirectory API. Zero upload.
Open toolDrop a folder and a glob pattern; only matching files are added to the output ZIP. Great for shipping a single component, language, or file type.
Open toolRun DEFLATE levels 1, 3, 6, and 9 on your files and see size vs time trade-offs side-by-side. Find the sweet spot for your data, runtime, and bandwidth budget.
Open toolStream ZIP construction one entry at a time using fflate's chunked API. Build archives larger than your browser's heap budget — useful for backups and dataset packaging.
Open toolZIP ↔ TAR.GZ ↔ GZIP, plus the universal format converter. 7Z write support is on the roadmap.
Repackage any ZIP archive as TAR.GZ — the standard for Linux distributions, Docker layers, and CI pipelines. Powered by fflate, runs entirely in your browser.
Open toolRepackage TAR.GZ as ZIP for users on Windows, macOS Finder, or any environment without tar installed. Browser-native, zero upload, lossless content transfer.
Open toolTake a single-file GZIP (.gz) and wrap it inside a ZIP container — useful when sharing with users whose tools don't recognize .gz directly.
Open toolBrowser-native LZMA write isn't possible without a heavy WASM bundle, so this tool re-packages your ZIP as TAR.GZ — the closest format we can produce locally that ships to 7-Zip / Keka / WinRAR users without any native tooling. Output is bit-lossless.
Open toolPick a target format and convert any input archive to it. Handles ZIP ↔ TAR.GZ ↔ GZIP in any direction. Browser-native, zero upload, no command line.
Open toolCRC32 integrity, compression ratios, type breakdown, metadata extraction, comment reading, format detection, and duplicate finding.
Verify every entry in a ZIP against its stored CRC32 checksum to detect corruption, partial downloads, or tampering. Browser-native, zero upload.
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 toolBreak 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's headers — version, OS, last modified, compression method, encryption flags, extra fields. Forensic-grade ZIP intelligence, zero upload.
Open toolDrop any file and reveal its true archive format. Detects ZIP, GZ, TAR, BZ2, XZ, 7Z, RAR by magic bytes — extension-independent. Browser-native, zero upload.
Open toolSHA-256 every entry inside an archive and group identical files. Spot duplicate logos, libraries, or .DS_Store waste. Reports total bytes recoverable.
Open toolRead the global comment embedded in a ZIP's End of Central Directory record — often used by build systems for build IDs, version stamps, or signing metadata.
Open toolGroup every entry in an archive by file extension and see counts plus uncompressed and compressed totals. Find dominant file types and dead weight.
Open toolRecover broken ZIPs, edit comments, normalise timestamps for reproducible builds, strip unwanted top-level folders.
Scan a damaged ZIP byte-by-byte for surviving local file headers and recover every readable entry into a fresh ZIP. Last-resort recovery, browser-native.
Open toolModify the EOCD comment of any ZIP file in place. Add build metadata, strip a leaked credential, or clear a comment for distribution. Browser-native.
Open toolSet every entry's date/time to a single UTC value. Essential for reproducible builds, deterministic CI, and bit-identical artifact comparisons.
Open toolStrip a common top-level folder (e.g. project-master/) from every entry in a ZIP. Cleans up GitHub release ZIPs and similar wrapped archives.
Open toolDetect ZipCrypto vs AES, generate per-file SHA-256 manifests, diff archives, verify passwords, read digital signatures.
Detect whether a ZIP uses legacy ZipCrypto, AES-128, AES-192, or AES-256 encryption. Critical before sharing — ZipCrypto is broken and should be re-encrypted.
Open toolCompute SHA-256 (or MD5, SHA-1) for every entry inside a ZIP and export the manifest as CSV or .sha256sums. Tamper-evident, audit-ready, browser-native.
Open toolDrop two ZIPs and see exactly what changed: added files, removed files, files with the same name but different content. Powered by per-entry CRC32.
Open toolType a password and instantly verify whether it unlocks an encrypted ZIP — no full extraction required. Useful for retrieving forgotten passwords from a list.
Open toolInspect any digital signature attached to a ZIP — PKCS#7 signatures, JAR signing, APK v1/v2 signatures. Browser-native, zero upload, forensic-grade output.
Open toolSplit a single archive into N parts, merge multiple archives into one, generate compression reports across many files.
Take an existing ZIP and split it into N parts of fixed byte size or fixed entry count. Faster than rebuilding from source files. Browser-native.
