FAQ

Yes. Our word counter algorithm matches the counting logic used by Microsoft Word, Google Docs, and standard word processors. Words are identified by whitespace delimiters and standard punctuation boundaries. Numbers and single-character words are included in the count, giving you consistent metrics across editing platforms.

Estimated reading time is calculated based on an average adult reading speed of 200 words per minute (wpm). Estimated speaking time uses a standard conversational speech rate of 130 words per minute. For short texts under one minute, times are displayed in seconds for quick reference during speechwriting or presentation planning.

Hyphenated words (such as 'state-of-the-art' or 'client-side') are treated as single compound words, matching the standard word counting rules of major word processors and academic guidelines. If you need individual word component counts, you can remove hyphens using the Find and Replace utility.

No. All processing happens entirely within your web browser using local JavaScript execution. Your text is never transmitted over a network, sent to external servers, or stored anywhere. The tool continues to work even if you disconnect from the internet after loading the page.

camelCase starts lowercase (userName), while PascalCase capitalizes every word including the first (UserName). PascalCase is commonly used for classes, camelCase for variables/functions.

snake_case is common in Python/Ruby and in database column names. kebab-case is used in URLs and CSS class naming because hyphens are more URL/markup friendly than underscores in many contexts.

Yes — acronym runs are kept together and then split before the next capitalized word, so inputs like XMLHttpRequest preserve the expected word boundaries.

Yes. The utility can handle thousands of characters instantly, limited only by your device's memory.

Absolutely. The conversion preserves whitespace and special characters, making it ideal for code identifiers and variable names.

Non-alphanumeric characters are stripped to create valid identifiers, which is standard for programming conventions.

Yes. Once the page loads, all functionality works without an internet connection.

Unlike many services, there's no API call, no tracking, and no ads — just pure client-side JavaScript.

It collapses extra spaces between words, trims leading/trailing whitespace, and reduces runs of multiple blank lines down to normal paragraph spacing.

No. It collapses excessive blank lines but preserves single line breaks and standard paragraph structure.

Copying from PDFs or Word often introduces irregular spacing, trailing spaces, and broken formatting. This tool normalizes that clutter so the text behaves consistently when you paste it elsewhere.

Tab indentation can be optionally trimmed, preserving the relative structure while normalizing the leading whitespace of each line.

Yes. Email replies often accumulate trailing spaces and irregular line breaks — this tool strips them in one pass.

The tool can replace tab characters with a configurable number of spaces, which is helpful when moving code between editors with different tab settings.

Word frequency ranks every word by how often it appears. Keyword density focuses on how often one specific target term appears as a percentage of total words.

Generally 1–2% for a primary term. Much higher can look like keyword stuffing to search engines.

Yes. By default, common words often dominate the list too — use frequency to inform editing decisions, not just to chase perfect percentages.

Currently the tool analyzes all words. You can use the Find and Replace tool to remove specific words before running the frequency analysis.

No. All words are lowercased before counting to provide an accurate aggregate of usage regardless of capitalization.

There is no hard limit. The tool processes text entirely in your browser and can handle documents of any size your device can manage.

A duplicate line remover is a web utility that scans text blocks or list files, identifies matching identical lines, and deletes extra repetitions while retaining unique lines.

You can open your file, copy the entire text content, and paste it directly into our online Duplicate Line Remover. Alternatively, desktop text editors like Notepad++ (Edit > Line Operations > Remove Duplicate Lines) or VS Code (Sort/Deduplicate extensions) can process files locally.

Yes, our browser-based tool can process tens of thousands of lines of text in real time. Because operations run client-side in your browser's memory, processing large blocks of text is extremely fast and secure.

To remove duplicate text, simply paste your content into the input field above. The tool automatically evaluates each line, strips out matching duplicates instantly, and produces a clean list ready to copy.

It uses the browser's built-in random number functions. Each line has an equal chance to be picked.

Only if Allow duplicates is checked. Otherwise, picks are unique for that run.

With duplicates off, you can't pick more unique lines than exist — the tool effectively caps at the total non-empty line count.

Yes. Paste any list where each item is on its own line. This includes CSV columns, spreadsheet rows, or any line-delimited data.

The tool uses Math.random, which is suitable for general randomization like contests and sampling. For cryptographic applications, use a dedicated UUID generator.

Spaces become hyphens. Accented characters are converted to their plain equivalent (é → e). Punctuation and special characters are stripped.

Google treats hyphens as word separators, while underscores can be read as word-joining. Hyphens are generally the SEO-friendly choice for URL slugs.

Yes. Slugs are lowercased to avoid case-sensitive URL issues and reduce duplicate-content variants.

Absolutely. Slugified names work well for filenames, asset naming, and any system that benefits from clean, URL-safe identifiers.

Emoji and other non-standard characters are stripped during conversion to maintain broad compatibility across URLs and file systems.

Yes. Toggle Use regex to enable full pattern matching, including capture groups.

Toggle Replace all versus First only depending on what you're correcting.

Yes. Toggle case-sensitivity off if you want Cat and cat treated the same.

Yes. When regex mode is enabled, you can reference capture groups using $1, $2, etc. in the replacement field to rearrange or transform matched content.

Yes. All matches are visually highlighted in the input area, making it easy to see what will be replaced before you apply the change.

The tool updates the input text in place. Consider keeping a backup or using the Text Diff Checker to compare before and after states.

Nothing directly. It's a scrambled fragment of a classical Latin text by Cicero (45 BC), altered centuries ago so it's intentionally nonsensical.

It mimics real letter and word-length distribution, so it looks visually realistic without distracting readers with readable, meaningful copy.

No. Search engines and users often flag it as low-value content — replace it before publishing.

Yes. Toggle the HTML option to wrap paragraphs in <p> tags and headings in <h2> tags, ready to paste directly into your templates.

Classical start uses the traditional 'Lorem ipsum dolor sit amet...' opening. Random start begins from a different point in the source text for variety.

Yes. The Copy button copies all generated text to your clipboard. You can also download it as a text file using the Download button.

It uses a Longest Common Subsequence (LCS) approach to identify shared portions, then highlights what's added, removed, or changed.

Yes. Toggle Ignore Case, Ignore Whitespace, or Ignore Empty Lines to focus on meaningful content changes.

git diff compares versioned files inside a repository. This tool compares any two text blocks with no setup required.

Added lines are highlighted in green, removed lines in red, and unchanged lines remain neutral. This color coding makes differences instantly scannable.

Yes. The Copy button captures the entire diff output, including the color-coded markers, for sharing or documentation purposes.

There is no server-side limit. The tool processes JSON entirely in your browser, so the maximum size depends on your device's memory.

Yes. Invalid JSON is detected instantly and the error location (line and column) is displayed, helping you find and fix syntax issues quickly.

Yes. The Minify button collapses formatted JSON into a compact single line, reducing file size for storage or transmission.

No. JSON does not officially support comments. If you need comments, consider using JSONC format or stripping them before validation.

Formatting pretty-prints JSON with indentation for readability. Validating checks whether the JSON is syntactically correct. The tool does both automatically.

Yes. Paste any JSON string from an API response, log file, or config file. The tool cleans and formats it with proper indentation instantly.

Base64 encodes binary data into ASCII text, making it safe to transmit over text-based protocols. Common uses include email attachments, data URIs in CSS, and encoding credentials in HTTP headers.

Yes. The encoder uses TextEncoder/TextDecoder with full Unicode support, so emoji, accented characters, and non-Latin scripts are encoded correctly.

The tool shows a clear error message explaining that the input is not valid Base64, helping you identify corrupted or incorrect strings.

Yes. The Swap button instantly flips input and output, making round-trip encoding and decoding effortless without manual copying.

No. Base64 is an encoding scheme, not encryption. It converts binary to text but provides no security — anyone can decode it back to the original content.

This tool is designed for text. For encoding binary files (images, PDFs), use a file-based Base64 encoder or your operating system's built-in tools.

This tool generates UUID v4, which uses random numbers. v4 is the most common version for general-purpose unique identifiers.

UUID v4 uses 122 bits of randomness, making collisions astronomically unlikely. For practical purposes, each generated UUID is unique.

Yes. Use the quantity selector to generate up to 100 UUIDs at once, displayed in a list for easy bulk copying.

Choose between lowercase with dashes (standard), uppercase with dashes, or no dashes (continuous hex string) depending on your use case.

Both. Click Copy on any individual UUID, or use the Copy All button to copy the entire generated list to your clipboard.

UUIDs are widely used as database primary keys, API request identifiers, session tokens, distributed system identifiers, and correlation IDs in logging.

The tool supports HEX (with or without #), RGB, RGBA, HSL, and HSLA. Enter a value in any format and see the equivalents in all others instantly.

Yes. Use the built-in color picker to select any color visually. The converter updates all format displays and the preview swatch in real time.

The color picker supports 8-digit HEX (with alpha) and RGBA/HSLA formats, though HSL and RGB displays show the base color without alpha.

HSL (Hue, Saturation, Lightness) is more intuitive for creating color variations — adjusting lightness for hover states or saturation for accessible contrast ratios.

Yes. Each format (HEX, RGB, HSL) has its own Copy button, so you can grab exactly the representation you need without manual selection.

The tool displays a clear error message and the preview swatch remains unchanged, so you always have visual feedback about valid and invalid inputs.

The tool supports headings, bold, italic, links, images, lists (ordered and unordered), code blocks, inline code, blockquotes, horizontal rules, and tables.

Yes. The tool shows a live rendered preview on one side and the raw HTML output on the other, with tabs to toggle between views.

Yes. GFM features like task lists, strikethrough, tables, and fenced code blocks with syntax highlighting are all supported.

Yes. The Copy button copies the raw HTML output to your clipboard, ready to paste into any CMS, email template, or web page.

Yes. The tool sanitizes the HTML output to prevent script injection and other XSS attacks, making it safe for use in web applications.

There is no hard limit. The conversion runs entirely in your browser, so the maximum document size depends on your device's available memory.

Yes. The clean HTML output works well in email templates. Use inline styles or additional email-compatible formatting as needed for your specific email client.
