Generate intentionally damaged test files to check how your applications handle corrupted data. Choose a file, select a corruption method, and download your test files directly in your browser.
Selected level: Moderate. The actual effect depends on the file format and the chosen corruption method.
Generate up to 10 test files in one operation.
Your original file remains untouched.
A corrupt file generator creates files with deliberately modified or missing data. Developers and QA testers can use these files to check how applications respond to unexpected input, damaged documents, and incomplete file content. This tool lets you create test files without intentionally changing your original file.
Use generated files to test upload forms, file readers, document processing systems, and error handling. They can help you see whether an application handles invalid files properly or displays a useful error message when a file cannot be read.
Keep a copy of your original test file and compare how your application handles valid and corrupted versions. For reliable results, test different file formats and corruption levels, and verify that your application rejects invalid files safely.
