Free, private text tools that run entirely in your browser
CoolTexTool is a collection of 15 free text utilities: a case converter, word and character counter, frequency analyzer, duplicate highlighter, whitespace cleaner, empty line remover, line sorter, number-to-word converter, T9 converter, Morse code converter, braille translator, NATO phonetic alphabet converter, upside-down text generator, text reverser and password generator. Everything is available in English, French and Spanish, with no sign-up and no fees.
Text cleanup is one of those small jobs that comes up constantly: a pasted list full of stray spaces, a headline in the wrong case, an essay that needs to hit a word limit, a spreadsheet column with duplicate entries. The usual search results for these tasks are crowded with pop-ups, forced registrations and pages that quietly upload whatever you paste. CoolTexTool was built as a calmer alternative: one clean workspace where each tool does one job and shows the result immediately.
Every tool is written in JavaScript that runs inside your own browser tab. The text you paste is never sent to our server, which means we cannot read it, store it or share it. You do not have to take our word for this: open your browser's developer tools, switch to the Network tab and use any tool. You will see no requests carrying your text. This is also why the tools keep working quickly on large inputs and why they still function if your connection drops after the page has loaded. Our Privacy Policy and Cookie Policy explain what limited data the site itself does collect, such as anonymous usage statistics.
The tools fall into five groups, and many people use them together:
Our tool guides go deeper on each tool, covering when to use it, the common mistakes people make and practical examples from writing, coding, data entry and everyday life.
CoolTexTool is built and maintained by an independent web publisher who also operates a small network of other free utility sites, including SamemaS (unit converter), TimeAndCal (time and calendar), SunorSnow (weather and climate), Beelad (country reference), YumyMetrics (nutrition and calories) and elCalculador (calculators). The shared goal across all of them is the same: simple, fast tools that respect the person using them.
The tools are free to use. To cover hosting and ongoing development, the site may display advertising served by Google AdSense. Ads never change how a tool works or what it does with your text, and we do not run sign-up walls or paid tiers.
If a tool gives a wrong result, a translation reads awkwardly, or you would like to see a new tool, we want to hear about it. Write to us at info@vyziotek.com or use the form on our Contact page. Reports of real errors are fixed as quickly as we can verify them.
