If you would like to know how different cases can be applied to your text, please read more below the converter.

Lowercase Converter – All Lower Case

The lowercase converter changes all text letters to small case letters (e. g., a, b, c, etc.).

When to use it: To fix accidental CAPS LOCK key usage or formatting issues.
More reasons to use it: To format URLs and emails or to write social media posts and text messages in a casual way.
SEO benefit: Search engines prefer lowercase letters in URLs. Converting uppercase to lowercase online with our tool will help you achieve that.

UPPER CASE All Caps Converter

The all caps converter transforms all text letters to uppercase (e. g., A, B, C, etc.)

When to use it: To make certain words stand out in a text or to make specific acronyms, or to write legal disclaimers and warnings.
Avoid using it: To type whole emails or documents in uppercase. Such texts are hard to read, and they may annoy readers since shouting in emails is considered impolite.

Sentence case

The sentence case converter capitalizes the first letter in a sentence and makes the rest of the letters lowercase, following the standard punctuation rules.

When to use it: For regular writing and any text that requires standard grammar.

Title Case Converter

The title case converter capitalizes major words and leaves minor words in lowercase.

When to use it: To format book and movie titles, blog post text, and email subject lines. This is a great way to make the lines easy to read and to make sure they appear properly in Google search results (especially to improve CTR – Click Through Rate).

Capitalized case

The capitalized case converter, also known as the Start case, capitalizes the first letter of every word in a text.

When to use it: For proper nouns, addresses, or data fields, for example.

Alternating & Inverse Case

aLtErNaTiNg cAsE: This case type alternates lowercase and uppercase letters. Mainly used in internet texting to convey sarcasm.

InVeRsE CaSe: The inverse case flips the case of all text letters. So, lowercase letters turn into uppercase letters and vice versa.

Advanced developer’s formatting: Kebab and snake case

While the lowercase, uppercase, sentence case, title case, and inverse case text converters are useful for writers and students, some of our users request more specific case conversion tools. These are the kebab-case and snake_case generators. Web developers and designers often need to format CSS class names or HTML ID names in kebab-case. Similarly, SQL and Python developers use snake_case for databases, Python scripts, or for naming variables in their code.

Kebab-Case

Kebab case is often used to format URLs or web slugs in a user-friendly way. Search engines can easily read such URLs and use them for their search results. That, in turn, improves the SEO of a website or a blog. Moreover, kebab-case is used for CSS class names and HTML ID names. A kebab-case generator replaces any spaces in a sentence with hyphens and removes any punctuation.

Snake_Case

On the other hand, snake_case is useful for Python and SQL databases, as well as for variable naming in Python coding. By using our generator, you can save time and effort by simply pasting a sentence and clicking the snake_case button to receive a properly formatted variable name.

Powerful Format Cleanup & Editing Tools

Have you ever copied text from a PDF document, old email, or scanned OCR photo only to have it appear with strange line breaks, enormous spaces, or double spacing? With our tool, you can use the Advanced Sidebar to clean up text in one click.

Remove Extra Spaces

Our tool helps to remove double, triple, or accidental trailing spaces, simply replacing them with one space, so you get perfectly formatted text.
Remove Empty Lines

Removes all empty return symbols, so you can make your poorly formatted text look good by pressing Ctrl+Alt+Enter instead of having large spaces between paragraphs.
Remove all line breaks

The ultimate PDF text cleaner, because it removes all line breaks and makes one big string of properly formatted text with no line breaks or symbol spaces.

Find & Replace Utility

Need to replace any brand name, text, or word in a large text document? With our Find & Replace utility located on the Sidebar, you can make global replaces of words in no time. Even better, the search is case-insensitive, which means if you search for the word "apple" it will replace "Apple", "APPLE", and "apple".

While our tool works in real-time as you're pasting or typing your text, this is only necessary for the next two features.

Real-Time Text Analytics: Word, Character & Read Time Counters

As you type, paste, or convert text, our tool acts as a character counter for measuring text length. You don't need a special character counter application because our sidebar automatically calculates:

Character Count: For fitting within social media's character limits for posts or tweets, or for SEO meta description's 150-character limit, or for SMS marketing.
Word Count: For knowing when you've reached a certain word count as a student, as a writer hitting their daily word count goal, or for SEO since 1,500+ word articles tend to rank better in search engines.
Sentence & Line Count: Knowing how many sentences and lines of text you have helps to determine how much information you're conveying with your text. In particular, if you have a high word count but low sentence count, it might mean your paragraphs are too long and need to be broken up for readability.
Reading Time: This measures how long it would take for the average reader to read your text. It's calculated based on 200 words per minute, so it helps to determine how long your article or speech might take to read.

100% Secure, Private & Offline-Ready

When performing any text conversion, especially for client work, company data, or any other private information, it's essential that you keep your data safe and secure. Most text converters available online work by sending your pasted text to a remote server, where it can be viewed and potentially misused by malicious hackers.

With our Case Converter Pro, all text processing is done locally by your browser. We use only local client-side JavaScript, which means your text never leaves your machine, and therefore can't be accessed by any remote server. In fact, you can even use Case Converter Pro while offline, since the only thing needed for it to work is your local browser. When the page loaded, you could disconnect your computer from the internet and still be able to use the tool.

Simply copy your text from Excel or Word, then paste it into the text converter, click the lower case option, and our Auto-Copy feature will automatically copy the converted text to your clipboard so you can simply hit "Ctrl+V" to paste it back in Excel or Word.
