18 browser-based utilities for editing, converting, counting and transforming text
Text is the raw material of almost everything we do online — emails, essays, code, captions, posts — and almost every text task has a fiddly manual version that wastes your time. The tools in this category exist to delete that friction. Each one takes text in, transforms or analyzes it instantly, and hands you a clean result you can copy with one click.
Everything here runs entirely in your browser with JavaScript. Nothing you type or paste is uploaded to a server, which means these tools are safe for sensitive drafts, private notes and unpublished work. There are no accounts, no limits and no watermarks — open a tool, do the job, move on.
Switch text between UPPERCASE, lowercase, Title Case, Sentence case and more in one click — ideal for fixing headlines or shouty emails. Open the Case Converter →
Live word, character, sentence and paragraph counts plus reading time and keyword density, updating as you type. Your text now auto-saves locally, so a draft is still there when you come back. Open the Word Counter →
Paste two versions of a text and instantly see what changed, line by line — perfect for comparing drafts or contract revisions. Open the Diff Checker →
Write Markdown on one side and watch the rendered result appear live on the other, so nothing surprises you at publish time. Open the Markdown Preview →
Encrypt and decrypt text with AES or encode it as Base64, entirely offline in your browser — useful for sharing notes with a shared secret. Open the Text Encryptor →
Work comfortably with right-to-left scripts like Arabic and Hebrew: set direction, fix mixed-direction text and preview the result. Open the RTL Text Tool →
How to Choose the Right Tool
If you're cleaning up capitalization, start with the Case Converter; for hitting a word or character limit, the Word Counter shows live statistics as you type. Comparing two drafts is the Diff Checker's job, while the Text Sorter and Text Replacer handle bulk line operations. For conversions — Morse code, binary, leet speak, emoji, HTML entities or URL encoding — pick the converter named for the format you need. And when you'd rather listen than read, Text to Speech reads your text aloud in a voice of your choice.
