Need a controlled broken file for testing or demos? Use Document Corruption to damage Word, Excel, PPT, and PDF locally in the browser. Originals are never uploaded. Pair with Document Fix.
Features
- Click or drag to upload multiple files:
docx / doc / xlsx / xls / pptx / ppt / pdf, up to 100MB each (max 10 in the list). - Files are queued with controlled concurrency; rows show Damaging… / Damaged / Failed.
- Successful outputs are named
*_damaged.<ext>; download one from its row or ZIP all successes. - Reset clears the queue and returns to the empty upload state.
When to use
- Creating sample bad files before testing Document Fix or other repair flows.
- Demonstrating open-failure / transfer-damage scenarios without hand-editing binaries.
- Batch-damaging several files and keeping only the successes.
How to use
- Open Document Corruption.
- Click the dashed zone or drop one or more intact documents.
- Wait for Damaged / Failed status in the list.
- Use the row Download or the bottom-right Download for all successes.
- Try Document Fix if you need to recover; click Reset to clear.
Notes
- Max 100MB per file; unsupported types and macro files are rejected.
- Processing stays in the browser; ZIP helpers may load from CDN on first use.
- Damaged outputs usually will not open in Office or PDF readers; do not use on unauthorized files.
- Encrypted files must be unlocked first; failed rows are kept for review.
