Web & Tech Tools
Format and validate JSON and encode/decode data. All tools run entirely in your browser: free, instant, and with no sign-up.
JSON Formatter
A JSON formatter is a tool that takes raw JSON data and makes it readable by adding indentation, line breaks, and consistent spacing. This free formatter validates your JSON as it formats, flagging syntax errors like missing commas or unmatched braces, and can also minify JSON into a compact single line, entirely in your browser.
URL Encoder/Decoder
A URL encoder converts characters that are not allowed in web addresses (spaces, symbols, and non-ASCII characters) into percent-encoded form such as %20, so links and query parameters transmit correctly. This free tool encodes and decodes URLs instantly in your browser, making it easy to build safe links or inspect encoded query strings.
Base64 Encoder/Decoder
Base64 is an encoding scheme that represents binary data using 64 ASCII characters, letting binary content travel safely through text-only systems like email, JSON, or HTML. This free tool encodes text to Base64 and decodes Base64 strings back to readable text instantly, with all processing done privately in your browser.
