Was macht ZIP Tools?
ZIP Tools hilft dabei, Daten oder Dateien umzuwandeln. Die Verarbeitung erfolgt im Browser und Grenzen werden klar beschrieben. Geprüfte Funktionen: Local multi-file ZIP creation, Archive listing before extraction, Selective file extraction, Size caps and CRC validation.
When should you use this tool?
Use this tool for small local file bundles and selective extraction. Use desktop archiving software for large, encrypted, multi-volume, or ZIP64 archives. It does not write extracted paths directly to your filesystem.
Wie wird es verwendet?
- Choose Create ZIP and select local files, or choose Inspect ZIP and select exactly one archive.
- Select Run. In inspection mode, review entry names and sizes, select files, then choose Extract selected files.
- Download the generated ZIP or each selected extracted file. Clear the workspace when finished.
Echtes Ein- und Ausgabebeispiel
Archive two local text files
Eingabe
hello.txt: Hello
empty.txt: (empty file)Ausgabe
ZIP entries:
hello.txt — 5 bytes
empty.txt — 0 bytesAn empty file is a valid archive entry. Inspection lists sizes without inflating file contents; extraction processes selected entries only.
Häufige Fehler und Korrekturen
| Symptom | Wahrscheinliche Ursache | Korrektur |
|---|---|---|
| The archive is rejected before extraction. | The file uses encryption, ZIP64, a split archive, unsupported compression, invalid headers, duplicate paths, or too many entries. | Export a standard single-volume ZIP using Store or Deflate; keep it within the displayed limits. |
| Extraction fails with a size or integrity error. | Declared expansion exceeds 100 MiB, actual output exceeds the validated size, or a selected entry fails CRC validation. | Use a smaller intact archive and compare it with the source; corrupted data is not offered for download. |
Supported behavior and limitations
Konkrete Grenze dieses Werkzeugs: Supports standard Store and Deflate ZIP entries. Encrypted, ZIP64, split archives and parent-traversal paths are rejected. Legacy non-UTF-8 filenames may display differently; prefer UTF-8 names. Downloads use the final filename, so folder hierarchy is shown in the list but not recreated on disk. Same-named input files must be renamed before packing.

ZIP Tools — FAQ
Is my input uploaded?
No. Processing happens in a browser Worker. Engine files load from this website; tool input, output, and filenames are not sent to a processing API.
Do I need an account or API key?
No account, API key, or backend processing service is needed.
How do I save a result?
Review the result, then use the Copy or Download control available for that output. Modifying input clears stale results.
