Technical Specifications

Exactly what each scope capitalizes.

Scope Rule
Every word (default) First letter of each whitespace-separated token uppercased; apostrophe words stay whole
Sentences First letter of the text and after each . ! ? uppercased; abbreviations shielded
First letter Only the first letter of the entire text uppercased; everything else untouched
Lowercase rest (default on) Whole text lowered first so SHOUTING input normalizes; off preserves iPhone-style capitals
Processing location 100% client-side JavaScript in your browser memory; nothing is uploaded
Usage limit None — capitalize unlimited texts for free, no signup required

Three Scopes

Words for titles, sentences for prose, first-letter for gentle fixes.

🧹

Shout Cleanup

Lowercase-first tames ALL-CAPS pastes while keeping intentional capitals optional.

🔒

Local Device Privacy

Everything runs in your browser with plain JavaScript. Text never leaves your device.

How to Use Capitalize Text

  1. Type or paste your text into the input box.
  2. Pick a scope: Every word, Sentences or First letter.
  3. Keep Lowercase rest on for shouty input, off to preserve brand casing.
  4. Click Copy Output or Download .txt to keep the result.
  5. Click Clear to empty both boxes and start over.

Capitalization That Looks Right

Random capitals signal carelessness: all-lowercase titles look unfinished, ALL-CAPS paragraphs feel like shouting, and mixed-case pastes from different sources look chaotic. Mechanical capitalization fixes the structure in one pass so human editing starts from clean text.

Words, sentences, or just the start

Titles and headings take every-word capitalization; body copy takes sentence capitalization; a single leading fix takes first-letter mode. The classic trap is apostrophes — naive tools produce Don'T — handled here by treating each token whole. Sentence splitting shields abbreviations the same way the Sentence Counter does.

Taming shouty text

Forum posts and legacy documents often arrive fully uppercased. Lowercase-first normalizes everything, then capitalizes exactly the chosen scope — “WELCOME TO THE SALE” becomes “Welcome To The Sale” instead of staying shouted. Disable it for camelCase identifiers and brand names like iPhone that must keep interior capitals. For full case systems, use the Case Converter.

Honest limitations

Mechanical rules cannot apply style-manual exceptions for minor words, nor recognize proper nouns needing capitals mid-sentence. Non-Latin scripts without case pass through unchanged. For very large pastes of tens of megabytes, live conversion on each keystroke can feel slower on older phones.

Privacy and Client-Side Security

Privacy Guarantee: All conversion occurs locally inside your browser. Your text is never transmitted, stored, or recorded on remote servers.

Many online tools send your pasted text to a server for processing. TinyToolzz takes a different approach: every replacement runs in the page itself with plain JavaScript.

Because nothing is uploaded, there is no waiting, no account, and no copy retained anywhere. Your text exists only in the tab's memory and is discarded when you close the page or click Clear.

Frequently Asked Questions

What does capitalizing text mean here?
Three scopes: Every Word uppercases the first letter of each whitespace-separated word, Sentences uppercases the first letter after each terminator, and First Letter touches only the very first letter of the whole text. Pick the scope that matches your target.
What does lowercase rest first do?
Enabled by default, it lowercases everything before capitalizing, so hELLO wORLD becomes Hello World. Turn it off to preserve existing capitals like iPhone or eBay while still fixing lowercase starts.
How are apostrophes and abbreviations handled?
Apostrophe words stay whole: don't becomes Don't, never Don'T. Sentence mode shields common abbreviations such as Mr., Dr., e.g. and a.m., so their periods never falsely start a new sentence.
How is this different from Title Case in Case Converter?
Every Word mode matches Title Case exactly, but this tool adds sentence and first-letter scopes plus the lowercase-first toggle in one focused page. For camelCase, snake_case and six other formats, use the Case Converter.
Is there a text length limit?
There is no fixed limit. The tool capitalizes documents of several megabytes in memory. Extremely large pastes (tens of megabytes) may respond more slowly because conversion runs on each keystroke.
Is my text uploaded to a server?
No. All conversion happens locally in your browser with JavaScript. Your text is never transmitted, stored or logged anywhere. Closing the tab or clicking Clear removes everything immediately.
