What Is a Corrupt File Generator?
A corrupt file generator creates an intentionally unreadable file of a chosen type and size. It is mainly used to test how apps and systems handle damaged files and error-handling. Just pick a format and size, then download the file.
How to use this tool:
- 1. Enter the desired file size
- 2. Select the size unit (Bytes, KB, MB, GB)
- 3. Enter a filename (without extension)
- 4. Choose a file extension from the list
- 5. Click "Generate File" and wait for the download
Common Use Cases:
- • Testing file upload systems
- • Checking storage capacity
- • Testing download functionality
- • Simulating large file transfers
- • Testing file handling systems
Legitimate Uses
| Use | Example |
|---|---|
| Testing error handling | Check that an app shows a proper error message |

Frequently Asked Questions
Dummy files are useful for testing various systems - checking upload limits, testing download speeds, verifying storage capacity, and testing how applications handle different file sizes and formats without using real data.
You can generate files from bytes up to gigabytes. Select your desired size and unit (Bytes, KB, MB, or GB). Note that very large files may slow down your browser, so be patient when generating files larger than 100MB.
The tool supports various common file extensions including document formats (PDF, DOCX, TXT), image formats (JPG, PNG), video formats (MP4, AVI), and many more. You can also generate files without any extension.
