Tamperlens

What is Tamperlens?

Black-boxed a name in a PDF and hit save? The text is usually still there. Tamperlens reads the file's paint order and tells you whether a redaction removed the text or just covered it — free, no signup, and the file is parsed in memory, never stored. Behind it: an API that reports structural fraud signals on PDFs, with evidence and the benign explanation for each. Signals, never verdicts.
