Why JSON and regex sit next to PDF tools

A lot of converter sites only sell PDF. We added a Developer module because the same constraint — do this in the tab, no account — is useful when you need to pretty-print JSON, test a regular expression, or decode a JWT header.

Those tools are not a cloud IDE. They will not deploy your app. They will format or convert the text you paste.

What we will not do with a JWT

The decoder shows claims. It does not verify a signature. The encoder builds an unsigned token for fixtures. Do not treat either as production security, and do not paste a live access token into a tool if you can avoid it — even a local one.

How this relates to ads

Developer pages are still real utilities. We keep ads off the policy pages and do not stack extra ad boxes in the article body. If an ad shows after you finish reading, it is the same in-content unit as on the rest of the site, not a fake “download” button.
