Append List Items – Merge Lists Tool Online
Append and merge lists instantly. Combine multiple lists with duplicate removal. Free, secure, client-side tool.
Text Tools collects the browser utilities a writer, editor, or developer reaches for when wrangling pasted copy, word and character counts, case conversion, find-and-replace, text diffs, sort, reverse, speech synthesis, and novelty effects like upside-down or bionic reading. A technical writer checking a 2,400-word API changelog can count words, swap camelCase field names to snake_case, and diff the draft against last quarter’s copy without opening a full editor. The category ships 22 free tools, all running client-side, so a pasted confidential brief never leaves the tab. No account, no file-size cap, no watermark.
What you can do with Text Tools
Count words, characters, and reading time, paste a draft into Word Counter for a live word, character, sentence, and reading-time readout.
Convert between cases, flip a headline from ALL CAPS back to Sentence case with Case Converter, or swap a JavaScript schema into Python with camelCase to snake_case.
Compare two versions of the same copy, Text Diff Viewer highlights word-level additions and deletions between an original and a revision.
Pick Text Tools when the input is plain prose. Character-level work on the Unicode side, decomposing an emoji skin-tone sequence, checking for spoofed Cyrillic letters in a domain, or normalizing combining marks, belongs in Unicode Tools. Base64, hex-to-ASCII, or URL-encoding a query parameter sits in Encoding Tools. For operations on a newline-separated list rather than a paragraph, use List Tools. For the full walk-through pairing each tool with a production scenario, see Free Text Tools: Edit, Format, Analyze & Generate.

Counters and analyzers surface the numbers writers and SEO teams check first. Word Counter keeps a live tally of words, characters, and reading time; Text Diff Viewer compares two drafts when edits arrive as a fresh paste.
Reshapers change the form of the text without changing its meaning. Case Converter flips between five case styles, camelCase to snake_case handles the identifier swap that usually costs a regex, and Find and Replace batches a rename across every occurrence in one pass.
Generators and novelty tools produce new output from the pasted seed. Text to Speech Generator exports an audio file, Bionic Reading Converter bolds the opening letters for skim reading, and Text to NATO, Upside Down Text, and Emoji Picker cover chat and phone-spelling.
How to choose the right Text tool
If you need a live word or character count while drafting → Word Counter.
If the source has inconsistent capitalization → Case Converter.
If a single term has to be renamed across a 5,000-word document → Find and Replace.
If two drafts of the same article need a visual comparison → Text Diff Viewer.
If a camelCase JSON schema has to become snake_case for a Python backend → camelCase to snake_case.
The single trade-off worth naming is scope. For a paragraph, a meta description, or a 5,000-word article, the browser tools are the fastest path, open the tab, paste, copy. For a 50,000-word manuscript or a recurring content pipeline, reach for a script or editor macro instead. The tab wins on one-off speed and loses on repeatability.
Frequently asked questions
Are these text tools really free?
Yes. All 22 tools run free in the browser with no account, no export limit, and no paid tier. Word Counter updates live as you type, and Case Converter returns the full output instantly. Processing happens client-side, so a confidential brief pasted in for counting never reaches a server.
How do I count words, characters, and reading time at the same time?
Paste the block into Word Counter. It returns word count, character count with and without spaces, sentence count, paragraph count, and an estimated reading time at roughly 220 words per minute. The character tally updates live, useful for hitting a 60-character title or 155-character meta-description target.
Can I convert camelCase to snake_case in bulk?
Yes. camelCase to snake_case accepts a list of identifiers, one per line, and returns the snake_case equivalent for each. That’s the usual path when a JavaScript API schema (userId, createdAt) has to match a Python or Rails backend (user_id, created_at) without hand-editing every field.
Which tool shows the difference between two versions of text?
Text Diff Viewer does. Paste the original on the left, the revised version on the right, and it highlights every word-level addition, deletion, and change. That’s the pick when an editor returns copy as a fresh paste rather than tracked changes.
Can I convert text to speech without signing up?
Yes. Text to Speech Generator reads pasted text aloud and exports an MP3 or WAV with voice, speed, and pitch controls. Supported languages include English, Spanish, French, German, Italian, and Portuguese, enough for a podcast intro or an audio newsletter.
What is bionic reading?
Bionic reading bolds the first few letters of each word so the eye anchors on a shape instead of re-reading the full word. Bionic Reading Converter reformats any pasted block into that style, useful for dense client briefs or long articles read on a phone.
How do I shorten text to a fixed character limit?
Text Truncator cuts at a character or word boundary with an optional ellipsis, the fastest way to shape a 300-word summary into a 155-character meta description or a 280-character post without lopping off mid-word.
