About these text tools

Working with text - counting it, reformatting it, copying it between contexts that demand different conventions - is a constant low-level task in writing, editing, coding, and content work. The tools here cover the two operations that come up most often: knowing exactly how long a piece of text is, and converting between the casing styles that different platforms expect.

Both run entirely in your browser. Whatever you paste in stays on your device - useful when the text contains anything you'd rather not upload to a third-party service.

When you'd use these

The casing conventions, briefly

Title Case capitalizes major words ("The Quick Brown Fox Jumps") - used for book and article titles. Style guides disagree on which short words to capitalize; most tools follow AP/Chicago rules and leave articles and short prepositions lowercase. Sentence case capitalizes only the first word and proper nouns ("The quick brown fox jumps") - increasingly the default for headlines on the web. UPPER and lower case are self-explanatory and rarely used in body copy except for emphasis or in technical contexts.

Word counts are usually based on whitespace-separated tokens, which matches what Microsoft Word and Google Docs report. Character counts can be measured with or without spaces - both are shown so you can match whichever standard your platform uses.

Frequently asked questions
Why does my word count differ from Word's?

Most discrepancies come from how hyphenated words are treated ("self-aware" as one word vs two) and whether numbers and standalone punctuation count. The differences are usually within 1–2%.

How long is 500 words to read?

Roughly 2–2.5 minutes at typical adult reading speed. The word counter shows an estimated reading time alongside the count.

What's the right case for SEO titles?

Either title case or sentence case works; consistency across your site matters more than which one you pick. Sentence case has been trending for the last few years.

Does the case converter preserve acronyms?

Title case and sentence case in this tool follow standard rules; if you have specific acronyms (NASA, USB, CEO) that should stay capitalized, you may need to manually re-capitalize them after conversion.

Why count characters with and without spaces separately?

Different platforms measure differently. Twitter counts everything; many academic submissions exclude spaces; SMS messages count everything including spaces and emoji.
