ZIP Extractor
Open a .zip file, browse its contents, and extract everything or just the files you select.
What is ZIP Extractor?
A ZIP browser and extractor. It reads the archive's central directory to list every entry with its real size and compression ratio, then decompresses only what you ask for.
How it works
The central directory is parsed straight from the file bytes, so the listing is instant and requires no decompression. Extracting an entry decrypts it (if the archive uses ZipCrypto), inflates the DEFLATE stream and verifies the CRC-32 recorded in the archive before handing the bytes over.
- Add your files. Drop files (or a whole folder) onto the drop zone. Browsers hand the contents straight to the page, so nothing is uploaded.
- Choose the options. Pick the format, compression, naming rule or split size. Any change re-computes the preview immediately.
- Download the result. Run the tool and grab the archive, the extracted files or the report. Multi-file results come back as a single .zip.
Examples
Pulling one file out of a 2 GB archive
The listing appears immediately from the directory record, and only the selected entry is decompressed — the rest of the archive is never touched.
Checking a download before trusting it
Sizes and compression ratios are shown per entry; a suspiciously tiny file where a large one is expected is a strong hint the archive is incomplete.
Common mistakes
Expecting ZIP to shrink photos, video or audio
Those formats are already compressed; deflate typically saves single digits on them. ZIP is at its best on text, JSON, CSV, logs and source code.
Treating ZipCrypto as real encryption
Traditional ZIP encryption is legacy and breakable. It stops casual snooping only — for secrets, encrypt the contents with AES-256 first.
Renaming extensions to convert a file
Changing .png to .jpg does not change the bytes inside. Some programs will refuse the file, or display garbage. Use a real converter when the format must change.
Splitting without keeping the suffixes
The parts carry .001, .002 … suffixes on purpose: the joiner orders them by number and fails loudly when one is missing, instead of producing a corrupt file.
Frequently asked questions
Can it open password-protected ZIPs?
Yes for traditional ZipCrypto encryption — enter the password and the entries are decrypted in the browser. Archives made with AES encryption are detected and reported, but not decrypted.
Why is there no “extract to this folder” button?
Browsers cannot choose a destination folder for downloads, and you would get a dialog per file. Multiple files are therefore repacked into a single .zip, which you unzip into the folder you want.
Does it modify my archive?
Never. The original file is only read; the archive you download for a multi-file extraction is a new one built from the entries you selected.
