## What it is
Depix is a proof-of-concept tool that recovers plaintext from pixelized screenshots by matching pixelated blocks against a rendered font search image. It demonstrates that pixelation is not a safe redaction technique for sensitive text.

## Use cases
- recover text from a pixelated screenshot
- test whether pixelation redaction is reversible
- demonstrate why pixelation should not be used to hide passwords
- deobfuscate censored credentials in shared images
- audit redaction practices in leaked documents

## When to choose
- you need to recover text redacted with pixelation using common fonts
- you want to demonstrate the insecurity of pixelation-based redaction
- you are doing security research on redaction techniques

## When to avoid
- the text was redacted with blurring or solid boxes instead of pixelation
- the font, size, or rendering of the original text is unknown or unusual
- you need a production-grade redaction tool rather than a research PoC
