Case Converter — How to Use It Online for Free
The Case Converter rewrites text in UPPER CASE, lower case, Title Case, Sentence case or aLtErNaTiNg case in one click. It fixes text typed with Caps Lock on, prepares clean headings, and saves the tedious job of retyping.
Case matters more than people think: ALL-CAPS text reads as shouting and is genuinely harder to read, while clean Title Case headings make documents and thumbnails look professional. Converted text is plain text — paste it into Word, a form or a caption box and it keeps its new case. The alternating case option is there for playful social posts and memes.
How to use the Case Converter
- Type or paste your text into the box.
- Click the case you want — UPPER, lower, Title, Sentence or alternating.
- The text converts instantly.
- Copy the result or download it as a .txt file.
A quick example
A student pastes an essay introduction typed entirely in capitals from a phone with Caps Lock stuck on. One click on Sentence case makes it normal, readable text — no retyping of 200 words.
Tips for better results
- Use Title Case for video titles, headings and names of chapters or products.
- After converting all-caps text, re-check names of people and places — they may need manual capitals.
- Download as .txt when you want to keep the converted version as a file.
Working with plain text
Plain text is the most portable format there is — it pastes into forms, documents, code and messages without carrying hidden formatting with it. Most text trouble comes from invisible things: double spaces, stray blank lines, trailing spaces, and encoding quirks picked up when text is copied from PDFs and web pages. The workflow that fixes almost anything is: clean first (remove extra spaces and duplicates), then transform (case, sorting, find-and-replace), then measure (word count). Because every tool here works on a pasted copy in your browser, you can experiment freely — your original document is never at risk, and nothing you paste leaves your device.
Common questions
What is the difference between Title Case and Sentence case? Title Case capitalises the first letter of every word (Used For Headings And Titles). Sentence case capitalises only the first letter of each sentence, like normal writing — use it to fix paragraphs typed in all caps.
I typed a whole paragraph with Caps Lock on. Which button fixes it? Sentence case. One click turns THIS IS MY REPORT into This is my report. If names inside it lost their capitals, fix those few words by hand afterwards.
Do I need to sign up or install anything? No. The Case Converter is completely free, needs no account and nothing to install — it runs in your browser, and anything you type stays on your device.
One tool rarely finishes the whole job. The natural companions to this one are covered in the Word Counter guide and the Remove Extra Spaces guide — between them, most text tasks can be handled end to end in the browser, with no installs and no accounts.
