Free Online Text Tools for Writing, Formatting, and Conversion
This text toolkit covers the writing and formatting tasks that come up constantly in technical, editorial, and everyday workflows: converting between Markdown and HTML, counting words and characters, cleaning up duplicate lines, changing text case, generating placeholder Lorem Ipsum, and comparing two pieces of text to see exactly what changed.
Each tool is deliberately simple, one job per page, no pop-ups, no signup, no paywall. Paste text in, get the result out. Everything runs in your browser so your drafts, notes, and snippets stay private even when they contain sensitive or unpublished content.
Why These Text Tools
Zero Data Leaves Your Browser
All processing is local. Your drafts, code snippets, and private notes are never sent to a server or saved anywhere persistent.
Focused and Fast
Each tool does one thing well. No bloat, no ads covering the content area, and no slow page loads.
Handles Large Inputs
Process entire documents, transcripts, or generated content. Browser-based tools are limited only by your device memory.
No Account Required
Open any tool and use it immediately. Bookmark your favorites and come back, there is nothing to sign up for.
Common Text Tasks
Users typically use these tools to:
- Convert a Markdown README into clean HTML for pasting into a blog post or CMS.
- Strip duplicate lines from a long export, log file, or list of addresses.
- Change a block of text from ALL CAPS into sentence or title case quickly.
- Count words and reading time before submitting an article, assignment, or social post.
- Compare two revisions of a paragraph or snippet to spot added, removed, or changed text.
How to Use the Text Tools
Every text tool follows the same simple flow:
- Pick a tool. Choose the counter, converter, generator, or comparator from the cards above.
- Paste or type your text. Drop text directly into the input field. Most tools accept large amounts of content at once.
- Copy or download the result. Click to copy the output to your clipboard or download as a text file.
