ZIP Extractor
Inspect and extract files from a standard ZIP locally, then download only the entries you actually need.
Processed in this browserOne ZIP up to 20 MB compressed, with no more than 200 files or 100 MB extracted. Encrypted and unsupported-method archives are rejected.
ZIP - 20 MB
No file upload
This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.
Original stays unchanged
The converter creates a separately named output. It never writes back into the source file.
Bounded work
One ZIP up to 20 MB compressed, with no more than 200 files or 100 MB extracted. Encrypted and unsupported-method archives are rejected.
Plain-language method
How extraction is bounded
The browser streams stored or DEFLATE entries, counts output bytes as they expand, rejects unsafe totals, flattens paths, and keeps each result available as an individual download.
- 01Choose a valid source
Use a standard, unencrypted ZIP. Damaged archives and ZIPs using an unsupported compression method will stop with a clear error.
- 02Review the conversion choices
There are no guessable options. The 200-file and 100 MB expansion limits are always enforced to reduce archive-bomb risk.
- 03Inspect the separate result
Review the entry list and download only needed files. Folder separators become safe filename separators.
Useful when
Practical jobs this tool handles
- Retrieve one document without uploading the archive.
- Inspect a small download before saving every entry.
- Recover files from a simple project ZIP on mobile.
Before converting
Treat extracted files carefully
- Do not open an unexpected executable merely because extraction succeeded.
- Check flattened names when different folders contained the same filename.
- Scan untrusted downloads with your device security tools.
Know the boundary
Extraction is not a malware scan
A valid ZIP can still contain harmful or misleading files. Nirmion checks archive structure and limits, not whether an entry is safe to run.
Quick answers
Questions before you convert
Extraction stays selective and transparent.
Why are files downloaded one by one?
Individual downloads let you inspect names and save only what you need instead of creating another archive.
Can it open password-protected ZIPs?
No. Encrypted archives are rejected rather than attempting password recovery.
Why did a small ZIP hit the size limit?
Highly repetitive data can expand far beyond its compressed size; the extracted-byte cap stops that growth.
