Whether you're writing documentation, wrangling API responses, or cleaning up data, you've probably reached for a text tool at some point. The problem: most are buried in clunky websites, littered with ads, or require creating an account just to paste some text.
Here are 10 free, browser-based tools at TextToolkit that are worth keeping in a bookmark folder. No login, no tracking — everything runs in your browser.
1. Text Formatter
Paste in a blob of text and the Text Formatter lets you trim leading and trailing whitespace, remove blank lines, fix smart quotes, and normalize line breaks all at once. It's the tool I reach for first when copy-pasting content from PDFs or Google Docs that comes in with all kinds of invisible formatting garbage attached.
Useful for: cleaning up user-submitted data, sanitizing content before importing it into a CMS, or just tidying up notes before sharing them.
2. Word Counter
The Word Counter does more than just count words. It gives you character count (with and without spaces), sentence count, paragraph count, and an estimated reading time — all updating in real time as you type.
If you write blog posts, README files, or API documentation with a target length in mind, having those numbers live on screen is genuinely useful. It also helps when a platform imposes a character limit and you need to hit it precisely.
3. Case Converter
The Case Converter handles UPPERCASE, lowercase, Title Case, Sentence case, and camelCase with one click. Sounds trivial until you've had to manually rename 40 CSV column headers or fix a block of text someone typed in all caps.
For developers, the camelCase conversion is especially handy when you're turning human-readable labels into variable names. Paste the text, click once, copy.
4. Remove Duplicates
Got a list with repeated entries? Remove Duplicates strips out repeated lines instantly. It's one of those tools you don't think about until you need it, at which point you're very glad it exists.
I use it when consolidating lists of URLs, email addresses, or tags from multiple sources. It can also optionally sort the output alphabetically, which makes the result much easier to scan.
5. Remove Extra Spaces
Double spaces, tabs masquerading as spaces, non-breaking spaces from web copy — the Remove Extra Spaces tool collapses them all down to single spaces. You can also strip all whitespace or trim just the leading and trailing spaces per line.
This one earns its place when cleaning text before feeding it into natural language processing pipelines or when you need consistent spacing in generated code.
6. Text Reverser
The Text Reverser can flip characters within each word, reverse the order of words in a sentence, or reverse the order of lines in a block of text. It's occasionally useful for debugging palindromes, writing gimmicky copy, or checking right-to-left text rendering behavior.
It's also oddly satisfying to use. Sometimes that counts.
7. Text to Speech
The Text to Speech tool uses your browser's built-in speech synthesis to read text aloud. It's handy for proofreading — you catch a surprising number of awkward sentences and missing words when you hear your writing read back rather than reading it silently yourself.
It's also useful for quick accessibility testing: paste in a chunk of content and get a rough sense of how it sounds to a screen reader user.
8. JSON Formatter
The JSON Formatter prettifies minified JSON into readable, indented output — or minifies it back when you need the compact form. It validates the JSON as it formats, so you get immediate feedback if there's a syntax error hiding in the payload.
Essential for reading API responses, reviewing webhook payloads, or debugging config files. No need to open a terminal or fire up a browser DevTools console just to make JSON readable.
9. Lorem Ipsum Generator
The Lorem Ipsum Generator gives you configurable placeholder text — choose how many paragraphs, words, or sentences you need. The output is standard Lorem Ipsum so it won't distract reviewers who see it in a design mockup.
Useful during early development when you need to populate a UI with realistic-looking content before the real copy exists. Having a fast, no-friction generator saves you from reaching for the same stack overflow answer every time.
10. URL Slug Generator
The URL Slug Generator converts any string into a clean, lowercase, hyphenated URL slug. It strips special characters, collapses spaces, and handles unicode characters gracefully.
Handy for generating slugs from blog post titles, product names, or category labels before feeding them into a CMS or router. It removes the tedium of manually replacing spaces and stripping punctuation.
Wrapping Up
None of these tools do anything you couldn't write a quick script for. The value is the speed and friction-reduction: open the tool, paste text, get a result, move on. No environment setup, no dependencies, no context switch into a terminal.
All of these run entirely in your browser — nothing is sent to a server, so you can safely paste internal content, API keys, or private data without worrying about it being logged somewhere. That matters more than people usually give credit for.
