GUW ZIP Repair (client-side, best-effort) — v1.0.1
Note: This is a best-effort, client-side recovery attempt. It may recover some files but cannot guarantee full restoration of complex/strongly-corrupted archives.
The GUW ZIP Repair tool helps recover files from damaged or truncated ZIP archives directly in your browser — no upload required. It scans for local file headers inside the archive and attempts a best-effort reconstruction so you can quickly download recovered files. If you need a full-featured archiving workflow (create, extract, batch tools), check out our GUW Free Archiver for advanced ZIP and archive management.
For specialized container formats or disc images, we also provide tools that complement ZIP repair workflows — for example, if your files came from an ISO or image file, try our ISO opener to inspect and extract contents safely before attempting repairs. This makes debugging where the corruption occurred much easier and speeds up recovery.
