Producing a deliberately damaged copy of a file

This tool creates an intentionally corrupted copy of a file that will no longer open properly.

It is often sought in order to pretend a submission failed. That is a poor idea: recipients generally recognise such a file, and the delay it buys costs more trust than it gains.

Legitimate uses

For checking how an application reacts to a malformed file: whether it shows a comprehensible message or fails uncontrollably.

Deliberately damaged test files are also useful for rehearsing recovery procedures and backup arrangements.

How to use it

Upload a copy of the file — never the original — and produce the damaged version, then label it so it cannot be mistaken for the real thing.

The damage is not reversible: the content cannot be recovered from the result.

Frequently asked questions

Can the file be repaired?

No. Be sure to keep the original.

Will the recipient notice it was damaged on purpose?

Usually yes. Deliberate corruption looks different from a transfer error and is recognisable.

Does the file size stay the same?

The size normally resembles the original so the file looks unremarkable at first glance, but the content is no longer readable.
