Base64 Encoder
Base64 Encoder helps you encode text or binary-safe content into Base64 in the browser for payload testing, code snippets, embeds, and transport-friendly values.
Open tool pageBrowser-Based Encoding and Query Tools
Encoding and query tasks are tightly connected: you build a query string, escape a value, inspect a URL, or decode an encoded fragment from a token or response. This hub keeps those related workflows together.
Why this hub exists
Encoding and query tasks are tightly connected: you build a query string, escape a value, inspect a URL, or decode an encoded fragment from a token or response. This hub keeps those related workflows together.
These hubs are designed to capture broader topic intent, then distribute that attention into the individual tool pages and long-tail guides that do the actual job.

Base64 Decoder
Base64 Decoder helps you decode Base64 strings in the browser so copied payload fragments, tokens, and encoded text are easier to inspect and reuse.
Open tool pageBase64 URL Encoder
Base64 URL Encoder helps you encode text with URL-safe Base64 characters in the browser so query values, token parts, and compact payloads can be reused without standard Base64 characters that often need escaping.
Open tool pageBase64 URL Decoder
Base64 URL Decoder helps you decode URL-safe Base64 text in the browser so token parts, compact payloads, and encoded query values can be reviewed without switching tools.
Open tool pageURL Encoder
URL Encoder helps you encode text for safe use in query strings, redirect parameters, and shareable URLs directly in the browser.
Open tool pageURL Decoder
URL Decoder helps you decode encoded URL text in the browser so query strings, campaign links, and copied parameters are easier to read.
Open tool pageURL Parser
URL Parser helps you break a URL into readable parts in the browser so you can inspect query parameters, confirm paths, and debug how an address is structured before you reuse it in code, analytics, or content.
Open tool pageQuery String Parser
Query String Parser helps you turn a query string into readable key/value pairs in the browser so campaign links, redirect parameters, and API query strings are easier to inspect and debug.
Open tool pageQuery String Builder
Query String Builder helps you build a query string from key/value lines in the browser so you can assemble links, redirect parameters, and filter states without hand-encoding every value.
Open tool pageJWT Decoder
JWT Decoder helps you decode a JWT so you can inspect its parts in the browser for reviewing token payloads, debugging auth flows, or checking claims during development.
Open tool pageJWT Generator
JWT Generator helps you build a JWT in the browser from header and payload JSON, which is useful for local testing, auth demos, and reviewing how token parts are encoded before they are sent anywhere else.

FAQ
Why group encoding and query tools together?
In practice, these tasks overlap whenever you are building links, reviewing tokens, or tracing how data moves through URLs.
Which tool should I use for ordinary query parameters?
URL Encoder and Query String Builder are usually the better first tools for ordinary redirect and tracking work.
When is URL-safe Base64 relevant?
It is relevant when you need encoded content that avoids characters that are awkward inside URLs or token segments.
