# URLEncoder.tools

> URLEncoder.tools is a free, privacy-focused suite of online developer tools for URL encoding/decoding, Base64 conversion, HTML entity encoding, query string parsing, and URL validation. All processing happens 100% client-side in the browser — no data is ever sent to a server. The tools are RFC 3986 compliant, support 12 languages, and require no login or registration.

## Core Tools

- [URL Encoder & Decoder](https://urlencoder.tools/en): Encode and decode URLs using encodeURIComponent, encodeURI, batch mode, or form data encoding. Supports Unicode, emoji, and RTL languages.
- [Base64 Encoder & Decoder](https://urlencoder.tools/en/base64-encode-decode): Convert text to Base64 and back. Useful for data URIs, API authentication tokens, and email encoding.
- [HTML Entity Encoder & Decoder](https://urlencoder.tools/en/html-encode-decode): Convert special characters to HTML entities (&, <, >, ", ') and reverse. Prevents XSS attacks.
- [Query String Parser](https://urlencoder.tools/en/query-string-parser): Parse URL query parameters into a readable key-value table. Debug complex API URLs.
- [URL Validator](https://urlencoder.tools/en/url-validator): Validate URL structure and view a breakdown of protocol, hostname, port, path, query, and hash components.
