The utilities you stop pasting into random sites
You paste a payload into an online JSON formatter without thinking. That payload sometimes has a customer in it.
Tools is a collection of over 130 utilities — JSON and XML formatters, encoders, converters, hash generators and more — with instant search, a consistent interface, no token cost and no usage limits. Everything runs in your browser; nothing is uploaded.
The offline part is the point
Convenience is the obvious pitch and it is the smaller half. The real argument is about where your data goes.
Pasting a response body into the first JSON formatter a search turns up means pasting it onto somebody else's server. Most of the time that is harmless. Occasionally the payload contains a customer record, an internal endpoint, or a token that was still valid — and nobody ever finds out, because nothing appears to go wrong.
A local tool removes the decision entirely. You stop having to judge each paste, which is the only way a rule like this survives a busy afternoon.
The ones you will actually use
Out of 130, most people settle on five or six. Predictably:
- JSON formatting and validation — for the response that came back on one line and the config file that is failing to parse.
- Base64 encode and decode — usually to read a JWT payload and find out why an auth check is failing.
- URL encode and decode — for the query parameter that broke because somebody put a slash in it.
- Hash generation — to check a file matches, or to reproduce a signature.
- Timestamp conversion — because logs are in epoch and humans are not.
Use the instant search rather than browsing the list. Typing what you want is faster than remembering which category somebody filed it under.
No tokens, no limits — and why that matters
These are not AI operations. They cost nothing from your balance and have no usage cap, so there is no reason to ration them.
Worth saying because people carry the habit over: if you are hesitating to format a large file because you are watching your AI budget, you are being careful about the wrong module. Save that caution for video generation.
Questions people actually ask
Does the data I paste leave my browser?
No. The tools run locally and nothing is uploaded. That is the actual reason to use them rather than the first formatter a search turns up — a pasted payload sometimes contains a customer record or a still-valid token.
Do these cost tokens?
No. They are not AI operations, they have no usage limit, and nothing is deducted from your balance. Do not ration them the way you would ration image generation.
How do I find the right tool out of 130?
Type what you want into the instant search rather than browsing categories. Remembering which category somebody filed a converter under is slower than describing it.
