Useful for generating SEO-friendly permalinks for blog posts, product pages, and CMS entries. ### [Case Converter](https://www.utilityforweb.com/case-converter/) Converts text between lowercase, UPPERCASE, Sentence case, and Capitalized Case (title case) instantly. Useful for cleaning up copy pasted from inconsistent sources or standardizing headings and labels. ### [Lorem Ipsum Generator](https://www.utilityforweb.com/lorem-ipsum-generator/) Generates placeholder "dummy" text (classic Lorem Ipsum) in configurable amounts to fill empty layout space during web and UI design mockups, before real copy is available. ### [Remove Line Breaks](https://www.utilityforweb.com/remove-line-breaks/) Strips line breaks and paragraph breaks from pasted text, collapsing it into a single clean line or paragraph — handy for cleaning text copied from PDFs, spreadsheets, or emails before reuse. --- ## Encoding & Decoding Converts data between Base64, URL, and HTML entity formats — used for safe data transmission, embedding in URLs, and correct HTML rendering. ### [Base64 Encode](https://www.utilityforweb.com/base64-encode/) Encodes plain text or string data into Base64 format, used for safely embedding binary-like data in text-based formats such as JSON, URLs, or email attachments. ### [Base64 Decode](https://www.utilityforweb.com/base64-decode/) Decodes a Base64-encoded string back into its original, human-readable text. ### [URL Encode](https://www.utilityforweb.com/url-encode/) Percent-encodes a URL or query string so that special and reserved characters (spaces, `&`, `?`, etc.) are transmitted safely over the web. ### [URL Decode](https://www.utilityforweb.com/url-decode/) Decodes a percent-encoded URL back into its original, readable form. ### [HTML Encode](https://www.utilityforweb.com/html-encode/) Converts special ASCII characters (such as `<`, `>`, `&`, quotes) into their equivalent HTML entities, preventing them from being misinterpreted as markup. ### [HTML Decode](https://www.utilityforweb.com/html-decode/) Converts HTML entities back into their original ASCII characters for display or further processing. --- ## Handy Design Tools CSS and color conversion utilities that support responsive design and consistent styling, plus bulk image format conversion. ### [PX to REM](https://www.utilityforweb.com/px-to-rem/) Converts CSS pixel (px) values to rem units, and vice versa, based on a configurable root font size — supports building responsive, accessibility-friendly stylesheets. ### [RGB to HEX](https://www.utilityforweb.com/rgb-to-hex/) Converts RGB color values into their equivalent HEX color codes for use in CSS, design tools, or brand style guides. ### [HEX to RGB](https://www.utilityforweb.com/hex-to-rgb/) Converts HEX color codes into their equivalent RGB values. ### [Image Converter](https://www.utilityforweb.com/image-converter/) Converts images between common formats (e.g. JPG, PNG, WebP) in bulk, directly in the browser. --- ## Web Development Tools Networking, security, and code-generation utilities for developers: IP and DNS lookups, QR codes, hashing, and password generation. ### [What's My IP](https://www.utilityforweb.com/whats-my-ip/) Displays the visitor's public IPv4 and IPv6 address. ### [IP Lookup](https://www.utilityforweb.com/ip-lookup/) Looks up geographic location, ISP, and other metadata associated with a given IP address. ### [MX Lookup](https://www.utilityforweb.com/mx-lookup/) Retrieves the MX (Mail Exchange) DNS records for any domain, useful for verifying email routing and deliverability configuration. ### [QR Code Generator](https://www.utilityforweb.com/qr-code-generator/) Generates a scannable QR code from any text, URL, or other data input. ### [QR Code Decoder](https://www.utilityforweb.com/qr-code-decoder/) Reads an uploaded QR code image and extracts the data encoded within it. ### [MD5 Generator](https://www.utilityforweb.com/md5-generator/) Generates the MD5 hash of any input string — commonly used for checksums and legacy data-integrity checks (not recommended for password storage). ### [Password Generator](https://www.utilityforweb.com/password-generator/) Generates strong, random passwords of a configurable length and character set for account security. --- ## JSON/XML Operations Tools for validating, formatting, and converting structured data between JSON, XML, and CSV formats. ### [JSON Operations](https://www.utilityforweb.com/json/) An online JSON formatter, validator, minifier, and beautifier — decode, pretty-print, or compress JSON data. ### [XML Operations](https://www.utilityforweb.com/xml/) An online XML formatter and validator — beautify or minify XML documents. ### [XML to JSON](https://www.utilityforweb.com/xml-to-json/) Converts XML data into equivalent JSON format in one click. ### [JSON to XML](https://www.utilityforweb.com/json-to-xml/) Converts JSON data into equivalent XML format. ### [CSV to JSON](https://www.utilityforweb.com/csv-to-json/) Converts CSV (comma-separated values) data or file content into JSON format. --- ##
