Unwrap email security gateway rewrites, percent-encoded characters, HTML entities, and optionally resolve URL shorteners.
Email security gateway rewrites
Proofpoint URLDefense (v1/v2/v3), Microsoft SafeLinks, Barracuda Link Protect — wrappers added by email security gateways are detected and stripped automatically.
Percent-encoding
URL-encoded characters (%XX) are decoded iteratively, handling double and triple encoding until stable.
HTML entities
HTML character entities such as &, /, and others are converted to their literal equivalents.
URL shorteners & redirects
Optionally follow HTTP redirects server-side to reveal the final destination of bit.ly, t.co, and similar shorteners. No content is fetched.
