Add your input, then select Parse policy.

How to use it

Paste a Permissions-Policy header value. Inspect disabled features and their declared allowlists.

What to keep in mind

Parsing does not establish support in every browser or evaluate iframe allow attributes.

Up to 2 MB per input, with smaller limits for complex operations. Clear removes the current input and result.
