FAQ

Is it free?

Yes. Every tool on the site is free to use, with no trial, no paid tier, and no usage limits for normal use.

Do you store what I enter?

For tools that run in your browser, no. The data you type is processed on your device and is never sent to a server, so there is nothing for the site to store.

The one server-backed tool sends only the input it needs to do its job - a domain name to look up. That input is used to produce your result and is not logged or kept, though the server still records basic request metadata such as your IP address and browser user-agent, as described in the Privacy Policy.

Do the tools work offline?

Browser-based tools keep working once the page has loaded, even if your connection drops. Paste JSON into the JSON Formatter or Markdown into the preview, for example, and the formatting and rendering happen on your device.

Server-backed tools need an active connection because the work happens on a server, not in your browser.

Which tools need a server, and why?

Most tools do not need one. A tool needs a server only when the browser cannot do the job on its own.

DNS Lookup is the clearest example: resolving a domain name requires talking to DNS infrastructure, which a web page cannot do directly. It is the only server-backed tool in the catalog, and it is marked "coming soon" until the server side is ready.

Is there tracking or advertising?

There are no ads and no ad-network code anywhere on the site.

The only analytics is a privacy-friendly, cookieless measure of page views (Vercel Analytics). It records aggregate traffic, not individuals, and it does not follow you across other sites.

What happens to a JWT I paste into the decoder?

Nothing. The JWT Decoder splits the token and decodes its header and payload in your browser. Tokens are not sent anywhere, not logged, and not stored.

One thing it deliberately does not do: verify the signature. Decoding shows you what a token claims; only the service that issued it, with the right key, can confirm those claims. Treat a decoded token as a claim, not a fact.

Can I suggest a tool?

Yes, and suggestions are welcome. Email hello@toolsforweb.com with what the tool should do and how you would use it.
